Après un mois de septembre relativement doux et un mois d'octobre particulièrement chaud, les températures ont accusé une baisse sensible à partir de mi-novembre. Moyennées sur la saison, les températures sont supérieures aux normales* de 0.7 °C. >> suite
Mitigation opportunities of black carbon emissions are presented and their effects are considered globally, in Europe and in Arctic area. The user can choose maps concerning black carbon and other short-lived climate forcers (SLCF); organic carbon and sulphur dioxide emissions, concentrations and effects nowadays and their development in years 2020 and 2030.
The biggest emission sources in Europe and Northern America are households that burn solid fuels for heating and diesel engines in the transport sector. In developing countries also solid fuel combustion in cooking stoves and traditional coke and brick making kilns are significant emission sources. >> More
On Nov.30, a meeting on promoting the Forecast System on Dynamical and Analogy Skills (FODAS) was held in Beijing. Representatives from 31 provincial climate centers attended the meeting.
FODAS system possesses the function of receiving real-time data, retrieving historical facts and model results, statistical-dynamic prediction for national and regional precipitation and temperature and others. Since its operation in 2009, it has provided accurate forecast on characteristics of China's main rain band during flood season for consecutive five years. It predicted successfully that China's precipitation was less than normal years generally in summer of 2009, and was more in eastern parts in 2010. And in 2011, it forecasted the precipitation was less in eastern China and was above-normal years in middle and lower reaches of the Yangtze River. In addition, FODAS also predicted successfully the rain bands moved towards the northward in 2012. The system forecasted successfully that there would be wetter in northern parts of China and South China, rainless in central parts in this year.
The system has been applied in thirteen provinces such as Beijing, Shanghai, Guangdong and Jiangsu. In recently, the system is approved by the State Copyright Bureau and will be promoted in the meteorological departments nationwide. >> More

The EEA estimates that the biggest risk to Europeans is caused by fine particles (PM2.5), especially in urban areas. Nearly one in three city dwellers in the EU live in areas where the fine particle content exceeds the limit set by the EU for protecting people's health. According to follow-up information from municipalities which was compiled by the Finnish Meteorological Institute, this limit was not exceeded anywhere in Finland in 2012. At all measuring sites, levels of fine particles fell below even the significantly more stringent recommendation set by the World Health Organisation. Only a tenth of Europe's urban population can enjoy such clean air. >> More
The El Niño-Southern Oscillation (ENSO) remains in a neutral state with all atmospheric and oceanic indicators within neutral bounds. International climate models surveyed by the Bureau indicate that the current ENSO-neutral state of the tropical Pacific will persist through to the end of the southern hemisphere summer.While ENSO is the dominant natural driver of Australia's climate, a neutral period does not guarantee a benign or normal season. A neutral ENSO period indicates that the tropical Pacific Ocean is not shifting the odds towards a significantly wetter or drier period for Australia. When ENSO is in a neutral phase, more localised weather extremes can and do occur due to the influence of secondary or local factors. For instance, near record warm sea surface temperatures around parts of the Australian coastline are currently likely to be influencing regional climate. >> More

Strictly speaking, the report of climate change impact is done by the IPCC Working Group II. In the future, the global temperature will rise. In China, the temperatures in the north will rise faster than in the south. That will affect China's climate system. In fact, China has a lot of extreme weather/climate events in recent years, such as heavy precipitation, extreme heat wave, as well as a small number of extremely cold weather events. In the future, we may see more hot weather. The arid regions may be drier and the humid regions may have more precipitation. Besides a few favorable effects, the warming will produce many adverse influences in a few aspects such as seal level rise, ice melting, food security, and health. >> More
Human role dominant in global warming
The human influence has been more and more evident due to two reasons. The first is better observation and the second is better understanding of the physical changes in the climate system, such as the uptake of heat in the ocean, the melting of Greenland and Antarctic, and the rising temperature in the atmosphere. Since 1850, the concentration greenhouse gases, most importantly carbon dioxide in the atmosphere, has increased due to emissions from the combustion of fossil fuels, land use, and cement production. Since 1950, this part of the driving factor of climate change has become dominant. >> More

On October 21, Volvo Environment Prize Foundation formally announced Chinese glaciologist and climate scientist Dr. Qin Dahe has been awarded the Volvo Environment Prize 2013. He is the first Chinese laureate. Throughout his very distinguished career, Dr. Qin Dahe has made outstanding contributions to the scientific understanding of the climate, both in China and at the global level. He has generated an exceptional body of research on the dynamics of glaciers and ice sheets, an important component of the climate system.
Dr. Qin’s scientific research record is remarkable. He has published 170 articles in English and another 230 in Chinese, comprising a major advance in our understanding of glacial processes. He has participated in or led many scientific expeditions to the Antarctic, Arctic, Qinghai-Tibetan plateau and Western China. His research on snow- to-glacier processes in Antarctica and in the Himalaya has been ground-breaking, and his innovative leadership in the use of ice cores in the Mount Qomolangma (Everest) region and in the mapping of Himalayan glacier resources has provided the basis for understanding the evolution of these resources and the baseline for assessing contemporary environmental change in the region. Beyond its scientific importance, Dr. Qin’s research on the Himalayan glaciers is critical for the future welfare of over a billion people, whose water supplies ultimately depend on a reliable source of water from these high altitude glaciers. Understanding how and why the dynamics of these glaciers are changing underpins the development of adaptive responses to ensure continuing water supplies.
Building on this impressive scientific base, Dr. Qin has played a leading role the pre- eminent assessment body for climate change, the Intergovernmental Panel on Climate Change (IPCC). He first became involved in the IPCC with its Third Assessment Report, published in 2001, and then assumed the prestigious leadership role of co- Chair of Working Group 1 (Science) of the Fourth Assessment Report, released in 2007. He has continued in this role in the Fifth Assessment Report, due to be released in October 2013. >> More

The Met Office will show its new leakage model along with its other Weather Intelligence. Models for demand, seasonal night use, pipe burst and turbidity data - at the UK Water Annual Leakage Conference, 24 October 2013.
Historically water leakage has been difficult for water companies to quantify or forecast accurately across water networks and resource zones, because of the large weather dependency. Understanding this weather dependency enables accurate modelling and reporting of the leakage.
Leakages account for up to 30% of the total annual distribution input across the water company's network. The Met Office's leakage prediction model assesses and predicts the influence of weather on leakage, which is known to particularly increase in periods of winter weather. The model allows for the close management of weather related leakage, on a week by week basis, enabling the water company to monitor and review its leakage strategy and expenditure on leakage reduction work can be set against levels of risk

The Bureau of Meteorology has issued its Tropical Cyclone Season Outlook for Australia today, reminding communities in northern regions to prepare now for the coming wet season.
The overall outlook is for near average tropical cyclone activity. The Tropical Cyclone Season Outlook uses sea surface temperature data and the Southern Oscillation Index to give an indication of what the coming season may bring. The current climate state is ‘neutral’, meaning there is neither a La Niña nor an El Niño acting to increase or decrease tropical cyclone activity around Australia.
More than a century of weather observations show that around 11 tropical cyclones form in the Australian region during a typical wet season. Around half of these have at least some impact on coastal regions, mainly affecting Western Australia, the Northern Territory and Queensland.
The 2013-14 Tropical Cyclone Season Outlook is available on the Bureau’s website at:http://www.bom.gov.au/climate/ahead/tc.shtml
14 October 2013 -Irish Met
A new decision support system is being provided by Met Éireann to provide guidance in emergencies related to the dispersion of hazardous materials in the atmosphere. The system provides a tailored service to users in the Environment Protection Agency (EPA), the Radiological Protection Institute of Ireland (RPII, currently merging with the EPA)
and the Department of Agriculture, Food & the Marine (DAFM). The system enables staff to track and forecast the movement of materials in the atmosphere, including their interaction with the environment.
For DAFM the system is primarily aimed at predicting the movement of Foot & Mouth virus particles in the event of an outbreak of the
disease. The system will be used by the EPA in the event of
emergencies related to chemical spillages, large fires or distant
volcanic eruptions that might compromise air quality over Ireland.
Likewise, the RPII will use the system for guidance on the dispersion
of radioactive materials released into the atmosphere
The year-to-date contiguous U.S. temperature was 55.9°F, 0.8°F above the 20th century average and the 28th warmest January-September on record. Above-average temperatures for the nine-month period were observed across parts of the West, where California had its ninth warmest January-September on record. The Northeast was also warmer than average. Below-average temperatures were observed across much of the southeastern quadrant of the Lower 48.
The year-to-date contiguous U.S. precipitation total of 24.76 inches was 2.09 inches above average and the 11th wettest January-September on record for the nation. This also marked the wettest January-September since 1998.
Much of the contiguous U.S. had near or above-average precipitation during the first nine months of 2013. Nine states in the Southeast, Midwest, and Northern Plains had January-September precipitation totals that ranked among the 10 wettest on record. Michigan had its wettest January-September on record with 29.69 inches of precipitation, 5.68 inches above average.
The south Peninsula consisting of five subdivisions (Tamil Nadu, Coastal Andhra
Pradesh, Rayalaseema, Kerala and south interior Karnataka) receives about 30% of its
annual rainfall during the NE monsoon season (October to December). Tamil Nadu in
particular receives about 48 % of its annual rainfall during this season. Due to this important
fact, IMD has been preparing experimental forecasts for NE monsoon season rainfall over
south Peninsula since 1998 using statistical models. IMD also continuously works to
improve the skill of the forecasting models. This year, for preparing the quantitative and
probabilistic forecasts for NE monsoon season rainfall over the south Peninsula, a 5-
parameter Principle Component Regression (PCR) has been used. Similarly a 4-
Parameter PCR model has been used for the forecasting season rainfall over Tamil Nadu.
Multi Model Ensemble Forecasts based on dynamical models from few important
international agencies were also examined for guidance.
El año hidrológico 2012-2013 ha sido muy húmedo en la mayor parte de España, con una precipitación media acumulada en el conjunto del mismo que ha alcanzado los 799 mm., lo que supone en torno a un 23% más que el valor normal. La anomalía positiva de precipitaciones del año ha resultado especialmente significativa en amplias zonas del tercio sur peninsular y en un área del alto Ebro.
Si se considera la distribución geográfica de las precipitaciones acumuladas en el conjunto del año hidrológico (ver mapa adjunto), se observa que éstas solo han quedado ligeramente por debajo de los valores normales en un área en torno al centro peninsular, así como en el extremo sureste peninsular, en la zona central de la comunidad de Valencia, en las islas orientales del archipiélago canario y en pequeñas zonas de Castilla y León y Cataluña. En el resto de España los totales acumulados superan a los correspondientes valores medios, llegando la diferencia sobre dicho valor medio a superar el 50% del mismo en dos extensas zonas, una que abarca el sur de Castilla-La Mancha y gran parte del centro y este de Andalucía y otra de tamaño algo menor que incluye Navarra, nordeste del País vasco, parte de La Rioja y extremo noroeste de Aragón.
A Met Office scientist has been recognised by the European Geophysical Union as its Outstanding Young Scientist for Climate Sciences. Dr Nick Dunstone has been given the award as part of the EGU's annual honours, which sees nominations made from across Europe.Nick has worked on monthly to decadal prediction since joining the Met Office five years ago and has carried out a series of high profile experiments to determine the causes of climate variability, particularly for the Atlantic. He was the lead author on a paper published in Nature Geoscience earlier this year which looked at the link between
aerosols, or dirty pollution, and the number of Atlantic hurricanes.

The Bureau of Meteorology has issued a Special Climate Statement on the record high temperatures for late winter and early spring affecting large parts of Australia. These recent record high temperatures follow Australia's hottest 12-month period on record with above average mean temperatures affecting the entire nation. The last week of August 2013 and the first half of September have seen record high temperatures for this time of year, affecting large parts of Australia (Figure 1 and 2). On the last day of winter, Australia recorded an average maximum temperature of 29.92 ̊C. A new daily record was also set for winter exceeding the previous record high by 0.19 ̊C (29.73 ̊C set on 23 August 1995). This was followed by an early arrival of very warm conditions with 31.45 oC recorded on 1 September for Australia-averaged maxima, setting a new record for the earliest 31 oC day by 15 days (previously 31.68 oC recorded on 16 September 1981). >> More
Between June and early October the Southeast Asian region experiences the Southwest Monsoon season, with the low level prevailing winds generally blowing from the southeast or southwest. This is also the traditional dry season in Brunei, Indonesia, Malaysia, Singapore and southern Thailand. During the Southwest Monsoon season, smoke haze that originates from widespread land and forest fires is a perennial problem that affects many areas of southern Southeast Asia. Most of these fires are due to land-clearing activities in some parts of the region. The resulting smoke is blown by the prevailing winds towards other parts of the region including Singapore, and is visible as moderate to dense haze. The smoke haze episodes affecting the region were particularly severe during the El Niño years in 1994, 1997 and 2006. >> More

Several regions of the NOAA-led U.S. Integrated Ocean Observing System (IOOS®) are partnering to deploy 12 to 16 autonomous underwater robotic vehicles, also known as gliders, from Nova Scotia to Georgia.
The gliders will be available through the peak fall Atlantic storm season to collect data on ocean conditions, which will help improve scientists’ understanding of hurricanes and pave the way for future improvements in hurricane intensity forecasts. >> More
More complex climate models make great demands on a well-functioning computer environment. In a newly established EU project, SMHI is developing and simplifying collaboration between researchers by building up the infrastructure and support services for climate research.
The climate models used to make calculations of the future climate are becoming increasingly advanced. They have higher resolution and contain more and more details and processes. This means that they require access to ever-larger supercomputers and better infrastructure to work.
"Advanced models make it difficult for researchers to process all the data unless there is an infrastructure to facilitate this. In this project we deal with many daily problems for climate researchers," says Uwe Fladrich, scientific coordinator for SMHI participation in the project. >> More

Summer temps were a bit higher than average throughout Finland, with Lapland being exceptionally warm. June and August were warmer than normal, while mean temperatures were reported for July.
According to the Finnish Meteorological Institute (FMI), the mean temperature for August was higher than normal throughout the country. Temperatures ranged from just over 17°C in the south and west coastal regions of Finland, to just under 13°C in the Käsivarsi region of Lapland. The biggest deviation from the long-term average was reported in the northernmost areas of Lapland, where temperatures were well over 3°C above normal levels. Smaller deviations, approximately 1°C, were reported in the western parts of Finland. >> More
The El Niño-Southern Oscillation (ENSO) remains neutral, with virtually all indicators at near-normal levels. Only cloudiness near the Date Line shows a weak La Niña-like signal. International climate models surveyed by the Bureau of Meteorology indicate that the tropical Pacific will remain ENSO-neutral for the remainder of 2013. Only one of the seven models surveyed suggests a brief period of La Niña-like cooling of the tropical Pacific.
The negative Indian Ocean Dipole (IOD) event has weakened considerably over the past month and a half, with IOD-neutral values prevailing since early August. The consensus of climate models is for the IOD to remain neutral for the remainder of the year, suggesting that the 2013 negative IOD is most likely at an end. >> More
The Japan Meteorological Agency (JMA) launched the Emergency Warning System on 30 August 2013. Emergency Warnings are issued to alert people to the significant likelihood of catastrophes in association with natural phenomena of extraordinary magnitude.
Residents should take all measures possible to protect themselves in the event that an Emergency Warning is issued.
On September 1, China Meteorological Administration (CMA) started to issue meteorological condition forecast of air pollution formally, and provide decision-making supports for governments and environmental protection departments. The new standard of forecast level is divided into six levels according to whether the meteorological condition is good for air pollutant dilution, diffusion and removal.
The meteorological condition forecast of air pollution is issued twice a day (at 8:00 and 20:00) to all-levels meteorological department, website, decision-making sectors, media, which is accessible for departments and the public.
Provisional Met Office statistics for this summer (June, July and August) show that this year has seen the warmest, driest and sunniest summer since 2006.
However, it's not a record breaker on any front - despite the prolonged heat wave experienced across the UK from the 3rd to 22nd July.
The early figures take observations from 1 June to 28 August, then assume average conditions for the final three days of the season - so the full-season figures could see some changes once all the information for August is available.
Using the estimates, the UK mean temperature for the summer is 15.2 °C, which is 0.8 °C above the average (all averages refer to 1981-2010 long-term average). It's likely this summer will finish around 8th to 10th warmest in the national record dating back to 1910.
Agosto ha sido en conjunto cálido a muy cálido, con una temperatura media de 24,4 ºC, valor que supera en 1,0 ºC al normal para este mes. Las precipitaciones han tenido una distribución muy desigual, aunque la media se sitúa en torno a la normal.TemperaturasAgosto ha sido en conjunto cálido a muy cálido, con una temperatura media mensual sobre España de 24,4º C, valor que supera en 1,0º C al normal para este mes (Periodo de Referencia: 1971-2000). Se ha tratado no obstante del mes de agosto menos cálido desde el año 2008 y el séptimo en orden descendente de temperatura media desde el inicio del presente siglo.
El mes ha tenido carácter muy cálido, con anomalías térmicas positivas superiores a 1º C en Galicia, Navarra, Madrid, Extremadura, Andalucía, Castilla la Mancha y Canarias, así como en el este de Cataluña, mientras que en el resto de España ha sido en general normal o ligeramente más cálido de lo normal. Las anomalías térmicas han alcanzado valores superiores a 2º C en algunos puntos de Canarias, Madrid y sur de Galicia.
Après un début d’année maussade et malgré un mois de juin frais et agité, la France a connu un été agréable, chaud et ensoleillé avec toutefois une forte activité orageuse en juillet.
Après un mois de juin très frais, les températures ont été estivales en juillet et en août, avec une vague de chaleur dans la seconde quinzaine de juillet. Moyennées sur la saison et sur la France, les températures sont supérieures aux normales* de 0.4 °C.
Sur l’ensemble de la saison, les pluies ont été peu fréquentes mais parfois intenses et accompagnées de chutes de grêle remarquables sous les orages. En juin, les pluies ont concerné essentiellement la moitié ouest du pays, puis en juillet le quart sud-est, la Corse et les Pyrénées. Le mois d’août, en revanche, a été peu arrosé. Sur l’ensemble de la saison, le nombre de jours de pluie est sensiblement inférieur à la normale sur la quasi-totalité du pays. Les quantités recueillies sont, quant à elles, légèrement inférieures aux valeurs saisonnières.
Après un mois de juin peu ensoleillé, le soleil a largement dominé durant les deux mois suivants, notamment en juillet. Les durées d’ensoleillement mesurées sur l’ensemble de l’été sont supérieures à la normale** sur toute la France.
The Climate Outlook for the 2013 “Short Rains” (OctoberNovember-December (OND)) seasonindicates that much of the
country is likely to experience depressed rainfall. This will
mainly be driven by the cooling of the Sea Surface Temperatures (SSTs) in the western Equatorial Indian Ocean adjacent to the East African coastline coupled with warmer
than average SSTs in the eastern Equatorial Indian Ocean adjacent to Australia (the so called negative Indian Ocean Dipole – IOD). The distribution of the rainfall in time and
space is expected to be generally poor over most places in the country.
In June 2013, many areas of the world experienced higher-than-average monthly temperatures. According to the latest statistics from NOAA’s National Climatic Data Center, the globally averaged temperature for the month tied with 2006 as the fifth warmest June since record keeping began in 1880. It also marked the 37th consecutive June and 340th consecutive month—that’s a total of more than 28 years—with a global temperature above the 20th-century average. The last below-average June temperature was June 1976 and the last below-average temperature for any month was February 1985.
Many areas of the world experienced much warmer-than-average monthly temperatures, including northern South America, the western and northeastern United States, much of Africa, western and central Europe, parts of southern Asia, and most of Australia. Parts of the central and southeastern United States, small regions across northern Canada, eastern Greenland, and parts of Mongolia and eastern Siberia were cooler than average. Far northwestern Canada and part of the eastern United States were much cooler than their long-term averages.
NOAA issued its updated Atlantic hurricane season outlook today saying the season is shaping up to be above normal with the possibility that it could be very active. The season has already produced four named storms, with the peak of the season – mid-August through October – yet to come.
“Our confidence for an above-normal season is still high because the predicted atmospheric and oceanic conditions that are favorable for storm development have materialized,” said Gerry Bell, Ph.D., lead seasonal hurricane forecaster at NOAA’s Climate Prediction Center, a division of the National Weather Service. “Also, two of the four named storms to-date formed in the deep tropical Atlantic, which historically is an indicator of an active season
Se ubicaría muy por arriba del promedio histórico de 13.2 ciclones anuales; hasta el momento se han presentado seis huracanes y dos tormentas tropicales
Para el Atlántico se mantiene el pronóstico de 18 ciclones con nombre, aunque se esperan menos huracanes que en el pronóstico previo
Durante la temporada de ciclones 2013 podrían registrarse en el Océano Pacífico Oriental 19 ciclones tropicales con nombre, de los cuales seis serían tormentas tropicales, ocho huracanes moderados (categoría 1 o 2 en la escala Saffir-Simpson) y cinco intensos (categorías 3,4 o 5), informó el Servicio Meteorológico Nacional (SMN), dependiente de la Comisión Nacional del Agua (Conagua).
La cifra representa un aumento considerable respecto de la estimación emitida por el SMN en abril, cuando se pronosticaron solamente 14 ciclones tropicales con la suficiente fuerza para ser nombrados, de los cuales seis serían tormentas tropicales, cuatro huracanes intensos y cuatro moderados.
Supporting the Bureau of Meteorology's capacity to respond to future extreme weather and natural disaster events and to provide seasonal forecasting services.
The Australian Government has announced measures to improve the Bureau's capacity to respond to future extreme weather and natural disaster events such as floods, fires, storms and tropical cyclones, particularly when these events occur simultaneously and in multiple locations.
In July 2011 the Government commissioned an independent review of the capacity of the Bureau of Meteorology to respond to future extreme weather and natural disaster events and to provide accurate and timely seasonal forecasting services. Undertaken by Ms Chloe Munro, the Review of the Bureau of Meteorology's capacity to respond to future extreme weather and natural disaster events and to provide seasonal forecasting services (the Review) proposed a suite of priority actions to address risks requiring attention, and additional options for further consideration by the Bureau and by the Government. The Australian Government's response establishes a new National Centre for Extreme Weather, increases frontline forecasters, builds new forecasting systems and delivers infrastructure upgrades in response to the highest priority actions from the Review.
El Niño Southern Oscillation (ENSO)-neutral conditions continued during June 2013, as reflected by near-average sea surface temperature (SST) across the central and east-central equatorial Pacific.Most model forecasts continue to indicate ENSO-neutral conditions through the remainder of 2013.
July to September: The period is the peak of the Southwest (SW) monsoon season, locally known as “Habagat” and tropical cyclone activity is likewise at its maximum. Much of the seasonal rainfall from various rain-causing weather systems can be observed over this period. Increased frequency of rainy days is one of the most notable characteristics of this season. Eight (8) to eleven (11) tropical cyclones (TCs) are likely to develop/enter the Philippine Area of Responsibility (PAR). During these months, storms move north of the Philippines, with a generally west northwest to northwest direction. Monsoon breaks are likely to be expected during the period. For July-August-September season, rainfall conditions will likely to be near normal in most parts of the country. During July, patches of below normal rainfall are likely over Palawan, SOCCSKSARGEN and Maguindanao. On the other hand, provinces of Quezon, Camarines Norte, Catanduanes, some provinces of Eastern Visayas, Davao Region, CARAGA and Autonomous Region for Muslim Mindanao (ARMM) will likely receive above normal rainfall conditions during August. Gradual recession of rains associated with the SW monsoon is expected during the later part of September up to early part of October.
Yesterday, Zheng Guoguang, Administrator of CMA conveyed the requirements of Chinese Premier Li Keqiang on flood prevention in Northeast China and typhoon defense in Guangdong. Dr. Zheng put forward five points to enhance monitoring and forecasting, and provide better meteorological service for flood and typhoon prevention. He urged meteorological departments to define job responsibilities, strengthen cooperation with each other and make resource integration to develop better monitoring & forecast. Meanwhile, the meteorological departments had better build special monitoring and forecasting groups, broadcast the weather condition & forecast for 24 hours and enhance refined forecast on the basis of the actual needs of floods prevention.
Moreover, it’s necessary to highlight monitoring & forecasting and consider every influence factors. For the Northeast China floods, it’s not only make the monitoring and forecasting for precipitation under the territory, but also take into account the upstream rainfall and water condition. For Guangdong’s condition, the results of previous severe precipitation and the present influence by severe storm Trami are equally important.
On August 16, the rainstorm and waterlogging risk warning service workshop was held in Nanjing, Jiangsu Province. The pilot work of national rainstorm and flood disaster regions division was initiated. Over 40 meteorological experts, technicians and managers from the meteorological bureaus of pilot provinces of meteorological disaster risk regions division including Hebei, Liaoning, Anhui, Fujian, Hubei, Jiangxi, Guangdong and Gansu and waterlogging risk evaluation provinces and cities including Beijing, Tianjin, Shanghai and Guangdong participated in the meeting. The implementation plan will be finished in the end of August.
In the meeting, chief researcher of National Climate Center Jiang Tong introduced the general implementation plan. The experts of the pilot provinces reported their implementation plans. Relevant experts from National Climate Center reviewed the plans and techniques as well as discussed how to better carry out the pilot work.
In summer 2013, temperatures continue to remain above normal in many parts of Japan, especially in western Japan. Ten-day mean temperatures averaged over western Japan were the third highest on record for three consecutive ten-day periods from the middle of July (11 – 20 July, 21 – 31 July and 1 – 10 August) in the JMA records since 1961. Since around 8 August, temperatures have been well above normal almost all over Japan and more than 3˚C above normal at a large number of observation stations mainly on the Pacific side in eastern and western Japan. On 11 August, the daily minimum temperature at Tokyo was as high as 30.4˚C. It was the first time for the temperature in Tokyo to remain over 30˚C for all day long since the daily observation started in 1875.
Since July, precipitation amounts continue to be below normal on the Pacific side in eastern and western Japan and in Okinawa/Amami. The precipitation amount from 1 July through 12 August was as little as 0.0 mm in Naze (Kagoshima Prefecture). In summer 2013, many parts in Japan, especially in western Japan, experience very high temperatures, while precipitation amounts are below normal on the Pacific side in eastern and western Japan as well as in Okinawa/Amami. Four stations recorded temperatures reaching or exceeding 40˚C, among which Ekawasaki (Kochi Prefecture) hit 41.0˚C, a new country record high temperature, on 12 August.

The Finnish Meteorological Institute (FMI) is continuing its co-operation, which got off to an excellent start, with the Department of Hydrology and Meteorology of Nepal (DHM) in a new FNEP2 project. The goal of the project is to improve Nepalese meteorological expertise and preparedness for natural disasters, which climate change is expected to increase in the future. The three-year project is an ICI (Institutional Cooperation Instrument) funded by the Finnish Ministry for Foreign Affairs. The project agreements were signed in the spring and summer, with the project launch slated for autumn of 2013.
Eurotunnel has chosen the Met Office to provide rail weather services for three years starting this starting this November.
The Met Office will help Eurotunnel reduce weather related disruption on the network through wind alerts, overtopping forecasts and a winter weather warning service.
The overtopping forecast will be used to safeguard the public who visit the award-winning Samphire Hoe nature reserve in Kent, a new piece of land created by Eurotunnel during the construction of the Channel Tunnel. The forecast provides details of prevailing sea conditions (including wind, water level, swell direction, wave height and wave period) both near shore and inshore at sea defences, providing a warning of the risk of waves breaching those defences.

Sunny, warm and dry – a picture book summer month
The start of the month saw a complete change in the weather: whereas low-pressure systems had determined the weather up to this point, high atmospheric pressure was now dominant. This high pressure brought exceptionally sunny weather and pleasant temperatures during the first two thirds of the month but later, as the weather became hotter and more sultry, it became very dry. There were severe localised thunderstorms with hail and large amounts of precipitation, as the initial analysis by the Deutscher Wetterdienst (DWD) of data from its around 2,000 weather stations shows.
Moyennées sur le mois et sur la France, les températures sont supérieures aux normales* de près de 2°C plaçant ce mois de juillet au 3e rang des mois de juillet les plus chauds depuis 1900, après 2006 et 1983. L’excédent atteint même 3°C dans le Sud-Ouest. Une période de très forte chaleur a concerné l’ensemble du pays du 15 au 27 juillet.

India Meteorological Department (IMD) issues operational long range forecasts for the southwest monsoon Season (June to September) rainfall over the country as a whole in two stages; in April and in June. Along with update forecast for the season rainfall over the country as a whole issued in June, forecast for monthly rainfall (for July and August) over the country as a whole and season (June to September) rainfall over the four geographical regions (Northwest India, Central India, Northeast India and South Peninsula) are also issued. From 2009, IMD started to issue forecast outlook for the rainfall during second half (August-September) of the monsoon season. This forecast is issued in the end of July. IMD has now prepared a forecast outlook for the second half of the 2013 monsoon.
(a) Rainfall over the country as a whole for the second half (August to September) of the 2013 southwest monsoon season is likely to be normal (94-106% of long period average (LPA)). However, the probability of rainfall to be below normal is also higher than the climatological probability.
(b) Quantitatively, rainfall for the country as a whole during the period August to September, 2013 is likely to be 96% of LPA with a model error of ±8%.
(c) The rainfall during August is likely to be normal (96 ± 9% of LPA) as was forecasted in June>> More

High-latitude marine expedition "Arktika 2013" organized by the Arctic and Antarctic Research Institute (AARI) started on June 1 aboard the nuclear-powered icebreaker "Yamal". It was organized for the emergency evacuation of a drifting research station "Severny Polyus-40", which was located on the northern periphery of the Canadian syncline of the Arctic basin in the coordinates 81,9 º NL 131,7 º WL. In May 2013 it moved in the zone of abnormal processes which led to the breaking of the station ice-field and threatened its activity. The expedition was led by the head of the High-Arctic expedition of the Arctic and Antarctic Research Institute Vladimir Sokolov. In order to reach the region of the drifting station as fast as possible the satellite data and aerial reconnaissance of the ice were used. >> More
Some of Australia’s most remote Australian islands and stations in Antarctica have been added to a network of environmental monitoring stations, which allows scientists to better understand long-term trends and changes in our climate.
Bureau of Meteorology Climate Monitoring Manager, Dr Karl Braganza, said that this network draws upon data collected at 112 locations across Australia, and now includes the addition of eight remote stations on Cocos Island, Lord Howe Island, Norfolk Island, Willis Island (Coral Sea), Macquarie Island and Mawson, Davis and Casey in the Antarctic.
"The Bureau’s climate monitoring network, known as the Australian Climate Observations Reference Network – Surface Air Temperature, is a high-quality, ground-based temperature record," Dr Braganza said. >> More
Recently, experts of National Climate Center analyzed the weather characteristics of this flood season. From June 1 to July 15, China saw many rainstorms with high intensity, and the precipitation reached the highest level in recent five years. Due to the extreme precipitation, floods and geological disasters were more serious. In addition, the number of typhoon was more than the long term average, and the landing time was earlier.
Since the flood season, the precipitation in most areas of North China, eastern and central-western Northwest China, central-northern Northeast China, western Sichuan Basin, western and northeastern Inner Mongolia was 20%-100%, 1-2 times more than the same period of normal years. Meanwhile, the precipitation in most areas of South China was less than the normal years. >> More
Over the past 25 years, an annual average of 6 to 7 tropical cyclones (TCs) made landfall on China mainland and Hainan Island with an average intensity of 29.9 m/s at landfall and maintained at least tropical storm intensity for 15.6 hours over land, leading to 505 deaths and 37 billion yuan in direct economic loss, which accounted for 0.4% of the annual GDP of China. Although there was little change in the overall landfall frequency, intensity at landfall and overland duration, the annual total direct economic loss increased significantly due to the rapid economic development over the past 25 years. Under global warming, the intensity of TCs that made landfall on Hainan decreased but the overland duration and frequency of TCs that made landfall on Fujian and Zhejiang increased. At the national and provincial levels, the ratio of the direct economic loss to GDP and casualties caused by landfall tropical cyclones decreased, suggesting the effectiveness of disaster prevention and reduction in China. >> More

More complex climate models make great demands on a well-functioning computer environment. In a newly established EU project, SMHI is developing and simplifying collaboration between researchers by building up the infrastructure and support services for climate research.
The climate models used to make calculations of the future climate are becoming increasingly advanced. They have higher resolution and contain more and more details and processes. This means that they require access to ever-larger supercomputers and better infrastructure to work.
"Advanced models make it difficult for researchers to process all the data unless there is an infrastructure to facilitate this. In this project we deal with many daily problems for climate researchers," says Uwe Fladrich, scientific coordinator for SMHI participation in the project.
On June 27, the President's Climate Action Plan called upon federal agencies to help communities around the nation become more resilient to and prepared for weather and climate extremes, such as drought. To further this call to action, NOAA this week added a new product to its toolkit that will give more timely and accurate drought predictions across the United States.
The new forecast-NOAA's monthly drought outlook-adds to the seasonal predictions issued by NOAA's Climate Prediction Center, and complements the weekly drought condition updates via the U.S. Drought Monitor. >> More

According to the Finnish Meteorological Institute, the mean temperature for June was above the long-term average in the whole country, in some places even exceptionally high. The mean temperature ranged from about 13 °C in Northern Lapland to about 18 °C in Southeast Finland. The previous time that June was hotter than this year in most of the country was in 1999. The greatest difference from the long-term average was recorded in Northern Lapland, where the temperature was up to four degrees warmer than usual. >> More
The low pressure trough will lie across Northern and Northeastern periodically. In addition,
Southwest monsoon still prevailing over the South Andaman Sea and Thailand will still be rather strong. These cause abundant rainfall with heavy to very heavy falls; bringing about flash floods and flooding events, especially around Northern, Northeastern and Eastern Thailand. During September: The low pressure trough will lie across Central, lower Northeastern and Eastern parts periodically. And the Southwest monsoon covering the Andaman Sea and Thailand will still be rather strong, causing abundant rainfall with heavy to very heavy falls; bringing about flash floods and flooding events, especially around Central, lower Northeastern and Eastern Thailand. During October: High pressure air masses from

A new international and interdisciplinary research programme, Baltic Earth, is launched. The aim of Baltic Earth is to achieve an improved understanding of the Earth system for the Baltic Sea region, focusing on physical and biogeochemical processes which interact in the atmosphere, in the sea including sea ice, and on land. Human interactions with the environment are recognized as an important part of the regional Earth system.
What determines the salinity dynamics in the Baltic Sea? What are the biogeochemical fluxes and feedbacks between the land and the sea? How can we predict extreme events like floods in the Baltic Sea region? What are the sea level dynamics in the Baltic Sea? What are the human impacts on the environment and how do they change the regional Earth system?
These are some core research questions, so called Grand Challenges, already identified for Baltic Earth. In order to tackle these questions, the new programme will combine an analysis of observations, multi-model systems and various outreach activities. >> More
Rarely has May in Germany seen so much rain. At the same time, the country was divided in terms of weather: a colder western half with very little sunshine and a quite warm eastern half with more sunshine. Deutscher Wetterdienst (DWD) press officer Uwe Kirsche took stock of the last four weeks: “It was definitely not the Merry Month of May as re-gards the weather, neither in terms of measured temperatures nor people’s perception,” as shown by the initial analysis by the Deutscher Wetterdienst (DWD) of the data from around 2,000 weather stations." >> More
Durante el mes de abril de 2013, en buena parte del territorio nacional se registraron cantidades de lluvia entre normal y ligeramente por debajo de lo normal; algunos déficits moderados se observaron en San Andrés y Providencia, La Guajira y en sectores de los Santanderes. Sin embargo, es importante señalar, que en el mes también se registraron algunas cantidades de lluvia ligeramente por encima de los valores medios de la época, en sectores de Arauca, Cundinamarca, Norte de Chocó, Atlántico, Cauca y Amazonas.
En los gráficos 1a, 1b, 1c y 1d, se detalla el comportamiento de las lluvias para algunas ciudades del país en relación con lo que llueve normalmente durante el mes (línea roja correspondiente al 100%); como se observa, solamente ciudades como Bogotá, Barrancabermeja, Valledupar y Villavicencio superaron esa condición media, mientras que en las ciudades restantes, se registraron déficits significativos, inclusive menores o cercanas al 50%, es decir, que solo llovió la mitad de lo que “normalmente” llueve, en ciudades como Ibagué, Pasto, Bucaramanga, Cúcuta, Rionegro, Cartagena, Barranquilla, Santa Marta, Riohacha, San Andrés, Quibdó y Buenaventura. >> Mas
The spring of 2013 in Germany was cool and wet but, above all, brought very little sunshine. All in all, the first five months of the year were among the three dullest starts to the year since sunshine measurements first began in 1951. Apart from a few very mild days at the start of March, wintry conditions dominated the spring weather right into April. Then, from mid-April, the weather was often sunny and warm. This continued in May, even in the east, until the wet and cool weather with very little sunshine that was being experi-enced in the west prevailed there too, as the initial analysis by the Deutscher Wetterdienst (DWD) of data from its around 2,000 weather stations shows. >> More

The Following conditions were observed.
Junio es como promedio el mes más lluvioso del año en Cuba. Una parte considerable de los acumulados de precipitación se produce asociada a eventos lluviosos de varios días de duración, los que ocurren principalmente en las primeras dos decenas del mes. Las precipitaciones dependen de la influencia de los sistemas migratorios de la zona tropical, tales como las ondas y las bajas tropicales, y de su importante interacción con sistemas de latitudes medias. La afectación directa de los ciclones tropicales es poco frecuente, pero cuando ocurre suele producir grandes precipitaciones. También se produce en junio el comienzo del período de gran actividad de las tormentas eléctricas, el que no comienza simultáneamente en todas las regiones y se manifiesta por un gradual incremento de su ocurrencia, principalmente durante la tarde y primeras horas de la noche, en asociación con el calentamiento diurno.
En los años 1998, 2000, 2001, 2004 y 2008, junio se presentó con grandes déficit en los totales de lluvia, principalmente como consecuencia de una inusual influencia anticiclónica en dicho mes. En este junio se espera que ocurran precipitaciones cercanas a lo normal en todas las regiones del país.
Normalmente, en junio la temperatura media se incrementa con respecto a mayo, y es en ocasiones un mes muy caluroso. En los últimos diez años se ha comportado con mucha frecuencia más cálido que lo normal, como han sido los casos de 1994, 1998, 2001, 2008 y 2010.

Mayo ha sido un mes relativamente frío en gran parte de España con una temperatura media de 14,6 ºC, valor que queda 1,3º C por debajo de la media de este mes. En cuanto a precipitaciones, ha sido algo más seco de lo normal, con una media en torno a 47 mm, cerca de un 25% menos que el valor medio.
Mayo ha sido un mes relativamente frío en gran parte de España. La temperatura media mensual sobre España ha sido de 14,6º C, valor que queda 1,3º C por debajo de la media de este mes (Periodo de Referencia: 1971-2000). Se ha tratado del mes de mayo más frío en conjunto desde 1985.
En la mitad norte mayo ha tenido en general carácter muy frío, con anomalías térmicas negativas que en amplias zonas superaron los 2º C, dando lugar a que en algunos observatorios del norte peninsular, como es el caso del de Santander haya sido el mes de mayo de temperatura media más baja ( con datos desde 1951). En la mitad sur ha tenido carácter frío con anomalías negativas iguales o menores de 1º C, con excepción de la mayor parte de las comunidades de Andalucía y Murcia, donde las temperaturas medias se mantuvieron próximas a los valores normales. En Baleares mayo ha resultado también frío a muy frío, mientras que por el contrario en Canarias ha sido más cálido de lo normal, especialmente en las islas más orientales. >> Mas
It is reported from CMA Department of Integrated Observations that from June 1, 16 new weather radars have been in operation in Yichuan of Heilongjiang, Taizhou of Zhejiang and Sanya of Hainan. Relevant services such as radar operation observation, data transmission and some others have also been carried out. These new radars will be used in nowcasting services for monitoring typhoon, severe convective weather and other emergency events.
It is introduced that to the end of 2015, 216 new weather radars will be constructed and put into use in China. Until the end of last year, 178 radars have been constructed among which over 160 are in operation already. The weather radar net covering key places of China have been fundamentally formed which can provide 24-hour real-time forecasting radar observational data for forecasting services in the flood season. >> More

Oceans are the earth’s largest sinks for carbon dioxide (CO2) emitted as a result of human activity, and the chemical properties of surface seawater change due to anthropogenic CO2 uptake. Ocean acidification, which stems from reduced seawater pH (hydrogen ion exponent), is a particular issue of concern because it accelerates global warming by reducing the capacity of oceans to take in CO2 from the atmosphere and affects marine ecosystems by disturbing plankton growth.
According to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC, 2007), it is estimated that average global surface seawater pH has decreased by 0.1 due to oceanic uptake of atmospheric CO2 emitted as a result of human activity since pre-industrial times (1750). Moreover, the outcomes of numerical model experiments based on future CO2 emission estimates indicate that surface seawater pH will further decease by 0.14 - 0.35 in the 21st century. >> More
Lower than average temperatures over the past fortnight have helped put this spring on track to be the coldest in more than 50 years, according to early provisional statistics from the Met Office.
The UK's mean temperature for the season (March-April-May) is currently 6.0 °C, based on figures from 1 March to 28 May, and assuming average conditions for the final 3 days of the month. The figures are unlikely to change much with such a short time left.

SMHI has used high-resolution satellite images for the first time to monitor ice break-up in Torne River, one of Sweden’s largest unregulated rivers.
The CryoLand research project has developed a method of identifying ice jams in the Torne River and flooded areas around the river using high-resolution satellite images.
“Radar satellite images with a resolution of 1-3 metres can be used to distinguish between water and ice. They provide a good picture of where Torne River has open water and where it is covered in ice. If ice jams are formed during the ice break-up they can be seen, along with their size and how large an area is affected,” says David Gustafsson, a hydrology scientist at SMHI. >> More

As spring arrives, many people are generally interested in the snow vanishing. Others are more interested in the water that is stored in the snow layer. Satellite measurements can show the extent and water content of the snow coverage, and where it will melt.
Scientists from SMHI are part of a European research project aiming to develop new, simpler ways of using satellite data about snow and ice.
Data from optical satellites can show the spread of snow coverage on a detailed level. Changes in the spread show where the snow has melted. This is valuable information in situations with high flows in watercourses as the snow melts. >> More

Le changement climatique a des effets visibles sur l’environnement en Suisse: c’est ce que révèle « Changements climatiques en Suisse », le nouveau rapport établi par les offices fédéraux de l’environnement (OFEV) et de météorologie et de climatologie (MétéoSuisse). Il présente les principales tendances à l’œuvre aussi bien que les champs d’action et remplace le rapport de 2007.
Les changements climatiques ont des répercussions sur de multiples secteurs en Suisse. Ils se laissent observer et sont illustrés à l'aide de près de 50 indicateurs. Le nouveau rapport intitulé « Changements climatiques en Suisse. Indicateurs des causes, des effets et des mesures » de l'Office fédéral de l'environnement (OFEV) et de l'Office fédéral de météorologie et de climatologie (MétéoSuisse) permet de constater les points suivants: les changements climatiques se font clairement sentir sur le cycle hydrologique, les glaciers, le pergélisol et la couverture neigeuse, ainsi que lors d'événements climatiques pouvant causer de graves dégâts comme les températures extrêmes, la sécheresse, les fortes précipitations, les crues, les éboulements et les coulées de boue. Les écosystèmes subissent également des transformations. Tandis que certains secteurs à la merci des aléas météorologiques, comme le tourisme d'hiver, l'énergie ou la santé, pâtissent des changements climatiques, d'autres en profitent, comme l'agriculture qui voit sa période de végétation se prolonger, mais seulement dans la mesure où le réchauffement reste modéré et ne dépasse pas 2 à 3° C d'ici 2050. >> Suite

In September 2012, the smallest ice spread to date in the Arctic was recorded. With data from satellites, scientists at SMHI have analysed changes in the atmosphere, and then compared the conditions for the ice melt in 2012 with 2007, the previous record low for ice spread.
“Satellite-based monitoring of the atmosphere can be an important source of knowledge in predicting extreme ice melts in the Arctic region,” says Abhay Devasthale, a scientist in atmospheric remote sensing at SMHI.
Three changes in the meteorological conditions were likely important factors in the low ice spread:
Since the past March, rain and snow continuously hit Northeast China. Temperature has been low and soil thaw slowly. So preparations for ploughing and sowing and spring sowing have been challenged. It is reported from CMO that in the coming 10 days, some new cold air will influence northern China again. So the temperature will sustain to be low. Temperature of Northeast China will be lower than the long term average. Such weather will badly influence spring sowing. Therefore, CMA and the meteorological bureaus of Heilongjiang, Liaoning and Jilin strengthen monitoring and consulting service to provide meteorological service for spring ploughing and sowing.>> More

New study shows clouds will be important in region’s future
The ICECAPS Mobile Science Facility at Summit Station against a backdrop of Arctic clouds. ICECAPS is short for Integrated Characterization of Energy, Clouds, Atmospheric state and Precipitation.
Clouds over the central Greenland Ice Sheet last July were “just right” for driving surface temperatures there above the melting point, according to a new study by scientists at NOAA and the Universities of Wisconsin, Idaho and Colorado. The study, published today in Nature, found that thin, low-lying clouds allowed the sun’s energy to pass through and warm the surface of the ice, while at the same time trapping heat near the surface of the ice cap. This combination played a significant role in last summer's record-breaking melt.
“Thicker cloud conditions would not have led to the same amount of surface warming,” said Matthew Shupe, research meteorologist withNOAA’s Cooperative Institute for Research in Environmental Sciences at the University of Colorado and the NOAA Earth System Research Laboratory. “To understand the region’s future, you’ll need to understand its clouds. Our finding has implications for the fate of ice throughout the Arctic.” >> More
According to a newly-published NOAA-led study in Geophysical Research Letters, as the globe warms from rising atmospheric concentrations of greenhouse gases, more moisture in a warmer atmosphere will make the most extreme precipitation events more intense.
The study, conducted by a team of researchers from the North Carolina State University’s Cooperative Institute for Climate and Satellites-North Carolina (CICS-NC), NOAA’s National Climatic Data Center (NCDC), the Desert Research Institute, University of Wisconsin-Madison, and ERT, Inc., reports that the extra moisture due to a warmer atmosphere dominates all other factors and leads to notable increases in the most intense precipitation rates. >> More

Atmospheric and oceanic indicators of the El Niño-Southern Oscillation (ENSO) generally continue within the neutral range. The recent increase in the Southern Oscillation Index (SOI) has been due to persistent high pressure weather systems in the central Pacific Ocean, and is not considered indicative of the broadscale climate. The SOI is known to be volatile at this time of year.
Summer ocean surface temperatures around Australia were the highest on record. Some cooling of the ocean off Australia’s northern coast has taken place in the last fortnight, in association with tropical cyclones Sandra and Rusty, but southern waters remain warm. High ocean temperatures may promote increased local rainfall in favourable weather conditions.
Climate models indicate the tropical Pacific is likely to remain ENSO-neutral through the first part of the southern hemisphere autumn. While it is known that predictions from dynamical models during the April through June period have lower skill, all models agree that an ENSO-neutral state is the most likely scenario for the next season.

Bogotá D.C., febrero 28 de 2013 (IDEAM): “Por primera vez, nuestro país cuenta con un documento completo que explica la historia y evolución de nuestras masas glaciares desde 1850 hasta nuestros días, lo que se constituirá en un insumo vital para la formulación de políticas públicas relacionadas con cambio climático y asociadas a estos ecosistemas de alta montaña”, aseguró Ricardo Lozano, Director General del IDEAM.
Este documento denominado “Glaciares de Colombia: más que montañas con hielo”, recientemente editado y publicado por el IDEAM, refleja que hace 160 años (desde 1850) en Colombia existían 17 masas glaciares y hoy sólo sobreviven seis, pasando de 374 Km2 a 45.3, en la actualidad, fenómeno que se aceleró durante los últimos 30 años. >> Más
Under normal condition, rain giving meteorological conditions starts to retreat gradually southwards starting from September which as a result, the northern half of the country are dominated by cool and dry air. In 2012/13, some parts of the country, particularly northern Ethiopia were dominated by dry and cold temperature. In association with this, the daily minimum temperature over the frost prone highlands of northeastern, southern, central and eastern attained freezing temperature as low as -3.5oC. During the month of October,100-207mm was observed over eastern Gambela, southern section of SNNPR, western and southern Oromiya and central Somali whereas, western Amhara, Benshangul-Gumuz, highlands of western and southern Oromiya ,western Gambela, eastern Tigray and most of Somali recorded 25-100mm. >> More

Know your risk. Take action. Be an example.
Be a Force of Nature this year with National Severe Weather Preparedness Week, March 3-9, 2013.
During this week, NOAA and FEMA are highlighting the importance of planning and practicing how and where to take shelter before severe weather strikes. Being prepared to act quickly can be a matter of life and death.
Being a force of nature goes beyond taking appropriate preparedness action. It’s about inspiring others to do the same. We’re asking people not only to be prepared, but also to encourage their social network to act by texting, tweeting, or posting a Facebook status update. >> More
The Hydrometeorological Prediction Center — one of the nine national centers of the National Weather Service — will now be known as the Weather Prediction Center. The change, which takes place on March 5, is meant to better reflect the diverse mission of the organization and provide a clearer and easier-to-understand name for the center, which is described in its strategic plan as “America’s go-to center for high-impact precipitation events and forecast guidance out to 14 days for a Weather-Ready Nation.”
“The new name captures the great breadth of products and services delivered each and every day and night of the year as the center works alongside the rest of the National Weather Service team to build a Weather-Ready Nation,” said Jim Hoke, director of the renamed center, located in the NOAA Center for Weather and Climate Prediction in College Park, Md. “Although our mission hasn’t changed at all, it is nice now to have a name everyone can understand, pronounce and spell.” >> More

Higher temperatures affect the conditions for cloud formation and rainfall. Heavy rain showers, such as summer thunderstorms, are influenced more by temperature than rain from larger widespread rain systems. Heavy rain has far-reaching consequences for society, and these could worsen at higher temperatures.
“Imagine a summer thunderstorm with sudden intensive rain showers over a short period. Compare that to rain from widespread cloud cover with lighter showers on and off over several hours. Both types can lead to extreme volumes of rain, but over completely different time periods,” says Peter Berg, a climate scientist at SMHI and one of the researchers behind a study into extreme rain showers published by Nature Geoscience.
The properties of rain showers
The volume of rain that falls in a heavy shower depends on the amount of water vapour in the atmosphere. At higher temperatures the atmosphere may contain more water vapour, thus increasing the chance of heavy showers. The properties of a rain shower are strongly dependent on the time scale being studied, from five minutes to several hours or days, for instance. The various types of precipitation are created in different processes in the atmosphere. This makes this a complex area from a research perspective. >> More
Millions of people in the region required emergency food aid after the failure of two rainy seasons - the 'short rains' (typically October to December) of 2010 and 'long rains' (March to June) of 2011.
Researchers used cutting edge 'climate change attribution' techniques to quantify how the probability of these two unusually dry rainy seasons may have changed as a result of human influence on climate.
Dr. Fraser Lott, an Attribution Scientist at the Met Office and lead author on the paper, said: "We found that the particularly dry short rains in 2010 were most likely caused by natural variability. However, the chances of long rains as dry, or drier, as those of 2011 were found to have increased due to human influence."
The study used state of the art modelling techniques to see how likely the weather patterns that led to the drought were. They looked at both a world with mankind's influence on climate, as well as 'the world that might have been' without manmade greenhouse gas emissions. >> More
According to NOAA scientists, the globally-averaged temperature for January 2013 tied with 1995 as the ninth warmest January since record keeping began in 1880. It also marked the 37th consecutive January and 335th consecutive month with a global temperature above the 20th century average. The last below-average January temperature was January 1976 and the last below-average temperature for any month was February 1985.
Many areas across the world experienced higher-than-average monthly temperatures, including Alaska, the eastern United States, southern Greenland, Uzbekistan, and Australia. Meanwhile, far northwestern and central Canada, the western United States, and a large swath of northern Eurasia were most notably below average.
This monthly summary from NOAA's National Climatic Data Center is part of the suite of climate services NOAA provides to government, business, academia, and the public to support informed decision-making. >> More
The annual anomaly of the global average surface tem-perature for 2012 was the eighth highest on record at +0.14°C above the 1981 – 2010 baseline.
Monitoring changes in temperature records on a decadal to centennial scale worldwide is of primary importance in ensuring scientifically sound diagnostics and understand-ing of the state of the climate. In its role as one of the world’s leading climate centers, the Japan Meteorological Agency (JMA) provides global mean surface temperature data (i.e., combined averages of near-surface air tempera-tures over land and sea surface temperatures) on a monthly, seasonal and annual basis, thereby helping to raise pub-lic awareness of global warming development. The annual global average surface temperature anomaly for 2012 was +0.14°C with the 1981 – 2010 average as a baseline. This ranks as the eighth highest figure since 1891 – the earliest year of JMA’s global temperature anomaly records. Warm temperature anomalies were noticeable especially around North America, from western Russia through to the Mediterranean, and over the Indian Ocean and the central part of the North Pacific Ocean. The average temperature over land areas alone was the sixth highest on record. >> More

O Instituto Nacional de Meteorologia (Inmet) ampliou sua capacidade computacional de 4 para 55.6 teraflops (Tflops), o que lhe permitirá realizar mais de 55 trilhões de cálculos por segundo. “Este foi o maior salto de desempenho em supercomputadores que o Instituto já deu até agora” afirma José Maurício Franco Guedes, consultor técnico e responsável pelo Centro de Computação Meteorológica de Alto Desempenho (CCMAD) do Inmet.
Gilberto Ricardo Bonatti, da Coordenação Geral de Modelagem Numérica, explica o que isto significa na prática. Hoje, o Inmet processa o Modelo COSMO (Consortium for Small-scale Modeling) com resolução horizontal de 7 km, cobrindo todo o Brasil, e com resolução de 2.8 km, para as regiões Nordeste, Sudeste e Sul, em etapas, o que leva cerca de cinco horas. A nova máquina vai processar o Modelo Cosmo 7 Km para o Brasil e 2.8 km para as três regiões ao mesmo tempo, com cerca de duas horas de processamento. Dessa forma, os meteorologistas terão mais tempo para elaborar suas previsões e, como será possível rodar o Cosmo a cada seis horas (00, 06, 12 e 18 UTC), eles poderão melhor acompanhar se os fenômenos severos estão enfraquecendo ou se tornando mais intensos. >> Más
Weather and Climate Change has become a newsworthy issue in most countries and Zimbabwe is no exception. The issue has become so topical such that almost everyone calls himself a ‘climate change expert’ hence the joke that ‘if you throw a stone in any street of Harare, they are chances that it will hit a ‘Climate Change Expert’’. But do we really understand Climate Change, its relation with weather and are we aware of what it can bring or what it means for us, let alone prepare ourselves to deal with its adverse effects as a nation?
Over the past few years we have seen many parts of Zimbabwe experiencing extreme events. Our winters have become so severe to the extent that many people’s horticultural produce which is a source of livelihoods for many has on many occasions been completely wiped out. We have had situations where the whole banana plantations, tomatoes and other vegetables are destroyed overnight by frost. So bad was the situation in certain areas that even chickens and in worse instances cattle also became victims. Whilst frost has been occurring over the past years, it is its severity, frequency and at times prolonged occurrence which is now worrisome. >> More
The chances of receiving above median rainfall during autumn are between 60 and 70% over much of SA, western NSW, southwest Queensland and the Pilbara and Gascoyne regions of WA (see map above). Such odds mean that for every ten years with similar ocean patterns to those currently observed, about six or seven years would be expected to be wetter than average over these areas, while about three or four would be drier.
In contrast, the chances of receiving above normal rainfall are between 30 and 40% in southern Victoria, Tasmania and southwest WA. In other words, the chances of below normal rainfall range from 60 to 70%. >> More
During the month of February, normally 5 Western Disturbance (WD) affect northwest India and adjoining areas. The frequency of WD in February 2013 till date is near normal as 3 WD affected the country. However, the WD in this month are active than normal as the induced systems associated with WD are seen either in the form of a depression or low pressure area instead of usual upper air cyclonic circulations. The quantity and spatial distribution of rainfall in the foothills as well as plains has so far been much higher than normal.
Some of the stations in northwest India have received cumulative rainfall from 1-18 February, 2013, which is much higher than the normal rainfall for the entire month. For example Lucknow has recorded 135.7 mm (1-18 February 2013), which is all time record for the month of February. At Dehradun, the precipitation is highest after 1961 and at Barmer also, the rainfall is highest after 1939. >> More

The aviation community, under the direction of the International Civil Aviation Organization (ICAO), came together across multiple time zones on 15 and 16 January 2013 for an international exercise called VOLKAM13 on volcanic eruption in the Far East of the Russian Federation.
The objective of the exercise was to test the flow of information about volcanic ash that is produced by the Kamchatka Volcanic Eruption Response Team in Petropavlovsk-Kamchatsky in the Russian Federation (KVERT), the Volcanic Ash Advisory Center (VAAC) in Tokyo, the Meteorological Watch Offices and the International NOTAM (Notice to Airmen) Offices.
During the exercise the explosive eruption of Karymsky volcano, located on Kamchatka peninsula, emitted volcanic ash to a height of about 12.5 km (FL410). The ash shifted to the southeast direction with a speed of 110 km per hour and caused pollution of the air space used for international airways (G583, B244, B932, G73). As part of the exercise, NOPAC (Northern Pacific) tracks were modeled. >> full text
Les chercheurs du Centre national de recherches météorologiques (CNRM-GAME, Météo-
France/CNRS) viennent de montrer que le lien entre enneigement automnal en Sibérie et rigueur de l’hiver en Europe, sur lequel s’appuient des méthodes statistiques de prévision saisonnière, n’était pas aussi robuste que de précédentes études auraient pu le laisser penser. Cette conclusion illustre la prudence qu’il convient de garder vis-à-vis des techniques empiriques de prévision saisonnière. Les résultats de ces travaux ont été publiés sur le site de Geophysical Research Letters1 le 16 janvier 2013.
Si elles donnent des résultats utiles sous les tropiques, les prévisions saisonnières restent peu fiables à
nos latitudes et sont l’objet d’intenses recherches dans la communauté climatique. La plupart des
centres météorologiques qui produisent ce type de prévisions utilisent des systèmes numériques
simulant de manière explicite la dynamique des océans et de l’atmosphère. Certains scientifiques
emploient cependant des méthodes purement statistiques, beaucoup plus simples et moins coûteuses
à mettre en œuvre, et parfois présentées comme aussi performantes. Il ne s’agit plus de simuler
l’évolution de l’atmosphère, mais d’utiliser des corrélations identifiées sur des séries de données aussi
longues que possible entre un phénomène climatique et les conditions moyennes en température ou en
précipitations quelques mois plus tard. D’aucuns avancent, par exemple, prévoir la rigueur de l’hiver en Europe sur la seule base de l’enneigement automnal en Sibérie. >> Suite

The UK Government has already made an investment in the development of a space weather prediction capability within the Met Office's existing scientific and forecasting capabilities. >> More
Summer season in this year is expected to start around second half of February and mainly maximum temperature will be not very hot. In first period, a high pressure area from China will still extend its ridge to cover the Northern Region and the Northeastern Region periodically. As a result, it will be still cool or cold weather in morning in the Northern Region and the Northeastern Region. While hot weather will take place almost everywhere in upper Thailand during the day. After that around mid March to May, thermally induced low pressure cells will emerge over upper Thailand in some period. In addition, usually have a confluence of southeasterly and southerly winds lie across the upper Thailand in some day. As a result, it will become hot and humid all over both regions, in the majority of such area and very hot in some locations on some certain days especially the Northern Region, the Northeastern Region and the Central Region.

Most of the east coast of Queensland, and the coast of New South Wales from the
Illawarra northwards, experienced very heavy rainfall during the period from 22 to 29
January 2013, as a result of the former tropical cyclone Oswald tracking southwards
along a track just inland from the Queensland coast. This rainfall resulted in severe
flooding in many areas within 200 kilometres of the east coast, most notably in the
Burnett catchment in Queensland and the Clarence catchment in northern New South
Wales, both of which reached record flood peaks.
Oswald formed in the Gulf of Carpentaria on 21 January, and made landfall that night
near Kowanyama, on the west coast of Cape York Peninsula, as a category 1 system.
It rapidly weakened after landfall and was downgraded to a tropical low on the morning
of 22 January. The low then moved near the east coast, being centred off Cooktown on
23 January and then tracked slowly to the south-southeast just inland from the coast. It
was centred near Townsville on the 24th, became slow-moving in the St. Lawrence-
Rockhampton area on the 25th and 26th, and then resumed a southwards track to be
centred near Dalby on the 28th. It then accelerated southwards and moved offshore
near Sydney on the 29th before moving out to sea. >> More

On January 28, China Meteorological Administration (CMA) revised warning signal of haze taking PM2.5 (a fine particulate matter) into consideration. At the same day, the Central Meteorological Office of CMA issued a yellow category haze warning in the first time as independent warning signal.
According to the new standards, haze warning falls into three categories: yellow, orange, and red separately indicating moderate, heavy, and extreme haze intensities. In the first time, PM2.5 is taken into consideration as same importance with atmospheric visibility, comparative humidity and other meteorological factors, reflecting air pollution conditions to the haze warning.
Since January this year, most parts of central and eastern China have seen large scale fog & haze weather, which produced adverse impacts to atmospheric environment, human health, and the on-going Spring Festival Travel. CMA urges all levels of departments to do a good job of observation and warning of haze and fog weather. (Jan. 30)
2012 went down in history of the Northern hemisphere as one of the warmest years. In accordance with the observations results since 1881 through 2003 its average annual air temperature calculated to within 0,1º, holds 5-7 place (together with 1998 and 2003) is among the warmest years since 1880. It’s warmer than 2011 having 9-10 rank, but is notably colder than 2010, the average annual temperature of which is an absolute maximum.

Data collected over the north Pacific Ocean the next two months by a highly specialized NOAA jet aircraft will improve North American winter storm forecasts.
Scientists aboard NOAA’s twin-engine Gulfstream IV-SP aircraft, typically used to study hurricanes, will measure wind speed and direction, pressure, temperature and humidity in areas of the Pacific where North American storms breed and where taking measurements is difficult and data is sparse. NOAA will fly out of Hickam Air Force Base in Honolulu, where the aircraft will be based through February. The aircraft will reposition to Anchorage, Alaska in March before returning to its home base in Tampa, Fla.
Data from the flights will be monitored by meteorologists aboard the aircraft and relayed as it is collected to NOAA National Weather Service forecasters on the ground, who will use the data in real time to improve forecasts of potentially extreme winter weather events across the entire country and extend those forecasts into the three- to seven-day ranges.
In the following 5 years, scientists will build a key technical business system platform for drought and flood prediction in different climate regions of southern China and evaluate risk levels of agriculture and water resources to drought and flood disasters in these regions. On January 25, a project named “Variation pattern, mechanism and relevant influences and responsive measures of drought and flood disasters in southern China in the backdrop of climate change” was started up. This project belongs to the National Basic Research Program of China (973 Program).
It is introduced by expert of National Climate Center Li Weijing that this project aims to research on variation pattern, forming mechanism, prediction theories and measures of drought and flood disasters in southern China in the backdrop of climate change. This research is linked with China’s disaster prevention and reduction and socio-economic sustainable development.
This project includes 6 sub-topics. Administrator of CMA Zheng Guoguang highly praised it. He expected the meteorological experts to work together and study these significant questions so as to develop the meteorological service. >> More
Au niveau national, la température moyenne de l'année 2012 s'est montrée 1.3 degré au-dessus de la norme 1961-1990. Les précipitations annuelles se sont avérées légèrement excédentaires avec un écart de 10% par rapport à la norme 1961-1990. L'année a démarré de manière très hivernale avec beaucoup de neige en montagne et une vague de froid en février. En revanche, le printemps a été extrêmement chaud, très ensoleillé et plutôt sec. Puis, l'été s'est péniblement installé et une période de fortes chaleurs ne s'est manifestée qu'au mois d'août. Après une première offensive hivernale au début de l'automne avec de la neige jusqu'en moyenne montagne, quelques magnifiques journées ensoleillées et très douces ont suivi en octobre, donnant un air d'été indien. Toutefois, à la fin du mois, il a neigé jusqu'en plaine. La neige est restée d'actualité en novembre avec une puissante offensive hivernale à la fin du mois au Sud des Alpes, en Valais et dans le Jura. D'autres chutes de neige ont touché l'ensemble de la Suisse au cours de la première quinzaine de décembre. >> Suite

Australia has started 2013 with a record-breaking heat wave that has lasted more than two weeks across many parts of the country. Temperatures have regularly gone above 48°C, with the highest recorded maximum of 49.6°C at Moomba in South Australia. The extreme conditions have been associated with a delayed onset of the Australian monsoon, and slow moving weather systems over the continent.
Australia has always experienced heat waves, and they are a normal part of most summers. However, the current event affecting much of inland Australia has definitely not been typical.
The most significant thing about the recent heat has been its coverage across the continent, and its persistence. >> More
Most areas of the world experienced higher-than-average annual temperatures, including most of North and South America, most of Europe and Africa, and western, southern, and far northeastern Asia. Meanwhile, most of Alaska, far western Canada, central Asia, parts of the eastern and equatorial Pacific, southern Atlantic, and parts of the Southern Ocean were notably cooler than average. Additionally, the Arctic experienced a record-breaking ice melt season while the Antarctic ice extent was above average.
The Finnish Meteorological Institute has provided weather services important to the safety and functioning of society for 175 years.
Finland’s climate is exceptionally challenging for the various functions of society, especially transport. The demand for new and increasingly sophisticated weather services keeps rising as society becomes more sensitive to the impacts of weather. “The Institute’s activities are centred on our customers’ needs,” said Director General Petteri Taalas. “We are an international forerunner in our sector. We are well prepared for this, thanks to our solid expertise, our highly advanced 24/7 production system, and the first-rate atmospheric and marine research conducted at the Institute.”
Merja Kyllönen, Minister of Transport and Communications, emphasised the Finnish Meteorological Institute’s role as a safety authority. “High trust is placed in the Institute and society uses the Institute’s services widely in planning daily activities, in providing for emergencies and in preparing for global climate change,” Minister Kyllönen pointed out.
David Grimes, President of the World Meteorological Organization (WMO) remarked that the research carried out by the Finnish Meteorological Institute has led to a much greater understanding of the complexities of the Earth system and its interactions with weather and climate. “The Finnish Meteorological Institute has proved itself to be a valued partner with WMO and a generous contributor to the global community,” Grimes commended. “The Institute is certainly one of the most advanced meteorological services in the world.”
Globally, despite the cooling influence of a weak-to-moderate La Nina at the beginning of the year, 2012 is still an unusually warm year in many parts of the world. In Hong Kong, 2012 started with significantly colder than normal weather in January and February which is mainly due to the stronger northeast monsoon over southern China usually in the presence of La Nina. However, with La Nina fading out in spring, the below-normal temperature was compensated by the exceptionally warm weather in April, May and August in 2012. Overall, the average temperature of 2012 was 23.4 degrees, 0.1 degrees above the 1981-2010 normal figure of 23.3 degrees (which is 0.4 degrees above the 1961-1990 normal figure of 23.0 degrees when we consider an earlier timeframe) and ranking the 12th highest since record began in 1885.
For extreme temperatures, there were 21 Very Hot Days, 23 Hot Nights and 21 Cold Days in 2012, about 11, 5 and 4 days more than the 1981-2010 normal figures respectively. The maximum temperature recorded at the Hong Kong Observatory in 2012 was 34.5 degrees on 28 August. During the passage of an intense cold surge of the winter monsoon, the minimum temperature of the year of 7.1 degrees was recorded on 31 December. This was also the third coldest New Year's Eve on record.
Wintry start to the month, then extremely mild at Christmas with lots of rain
In December2012 the weather in Germany was mostly dominated by low pressure systems – first bringing snow and then rain. Initially, these systems often brought cold air but predominantly mild air followed. The prevailing weather at Christmas was unusually mild and temperatures were even spring-like. Overall, this caused December to be a little too warm but much too wet, with slightly below average sunshine, as the initial analysis by the Deutscher Wetterdienst (DWD) of data from its around 2,000weather stations shows. >> More
Overall, 2012 was somewhat warmer than normal, with slightly less rainfall than usual and a positive total amount of sunshine. Individual months were, however, highly changeable and, in some cases, extreme weather situations occurred. New weather records were set in some places, as the initial analysis by the Deutscher Wetterdienst (DWD) of data from its around 2,000weather stations shows.
At the beginning of the year there were strong westward currents, bringing very mild weather. A pronounced high pressure system in the first half of February brought extremely cold air to central Europe, to the extent that numerous lakes and rivers froze over. This was followed by a further period of warm and relatively dry weather from mid-February onwards, with exceptionally sunny weather prevailing in March. Initially, April was relatively cool but an unusual advection of warm air masses at the end of the month set new seasonal records. Rapid temperature fluctuations also continued in May. The start of the summer saw widespread rainfall, followed by very hot and thundery weather with temperatures almost reaching 40degrees. Autumn brought some summer-like weather, setting records for warm temperatures in October but this was followed by a sharp early onset of winter. The weather during the first half of December was wintry throughout Germany but, after that, only the north-east was affected by the snow and cold. A thaw had set in everywhere at Christmas, with spring-like warmth even extending to the highest mountain regions. >> More
On January 14, 2012, China Meteorological Administration (CMA) issued the China Climate Bulletin in 2012. According to Bulletin, the general characteristic of China climate in 2012 was wet with near normal (the average of 1981-2010) temperature. However the regional and period meteorological hazards were serious and frequent.
In 2012, the annual precipitation was above normal and the mean temperature was near normal in China both with severely uneven distribution in time-space and intra-seasonal variability. The mean of annual total precipitation in China was 669.3 mm, 6.3% more than normal and 20.4% more than 2011. The total precipitation was less than normal in winter, but much more in spring, summer and autumn consecutively in China. The annual mean temperature was 9.4℃ , which was near and slightly below normal (with -0.2℃ anomaly) but 0.3℃ less than 2011. The mean temperature was lower than normal in winter and autumn, but higher than normal persistently in spring and summer in China. >> More
On January 14, 2012, China Meteorological Administration (CMA) released the No.1 issue of China Greenhouse Gas Bulletin, which is made by the Climate Change Centre of CMA.
Since 1980s, China Meteorological Administration (CMA) has put in place seven atmospheric background stations-Waliguan in Qinghai (WLG), Shangdianzi in Beijing (SDZ), Lin'an in Zhejiang (LAN), Longfengshan in Heilongjiang (LFS), Shangri-La in Yunnan (XGL), Jinsha in Hubei (JSA) and Akedala in Xinjiang (AKD), which represent a number of typical climatic, ecological and economic zones in China. Greenhouse gases and related tracers have been observed by network stations in a standard and consistent routine in response to the Kyoto Protocol and the Montreal Protocols. In particular, the Waliguan Global Atmosphere Watch Baseline Observatory has engaged in flask air sampling analysis since 1990 and in-situ observation since 1994. The 20-year history in observation rewards the longest time series in atmospheric CO2 records in China. The flask air sampling analysis and the in-situ observations were launched in other background stations beginning from 2006. >> More
Choked in dense smog for three consecutive days, Beijing started emergency response measures on Sunday to curb the air pollution at hazardous levels.

In case of the Central Region and the Eastern Region, it will be cool weather almost everywhere and foggy in the morning while cold weather will be observed in some places certain days. For mountainous areas, it will be cold or very cold weather throughout the period. Moreover, hoarfrosts are also expected at times. >> More
The Bureau of Meteorology confirms extreme temperatures to continue for the next week, and provides a round-up of national temperature records broken during the January heatwave.
Assistant Director of Weather Services, Alasdair Hainsworth, said the heatwave had proven to be every bit as severe as forecast, both in the huge area affected and in the temperatures recorded.
"The cool change across southeastern Australia last night has delivered some relief for southern Australia, but we are by no means through the woods yet, with very hot temperatures forecast for Western Australia today, and building again throughout central Australia," said Mr Hainsworth.
"The late onset of the monsoon, that would bring some relief in the way of cloud cover and rain, has not yet eventuated. As a result extremely hot air masses are developing in the north of the continent and being driven into southern Australia ahead of each cold front.
""The strong, gusty winds associated with these fronts, the high fuel loads which continue to dry out following a drier than average end to 2012, and extreme heat in January are causing extremely challenging fire conditions for our emergency services partners. >> More
The average annual air temperature in Croatia for 2012 was above the multi-annual average (1961-1990). Average annual air temperature anomalies were within the range from 1.1°C to 2.2°C.
According to percentile classification, thermal conditions in Croatia for 2012 have been described by dominant category extremely warm except an area in western part of Slavonia which belongs to the category very warm.
On January 9, the monitoring from FY-3 meteorological satellite shows that the Liaodong Bay, Bohai Bay and Laizhou Bay have been covered by sea ice. In Bohai, the area of sea ice covers about 24,700 square kilometers.
It is reported that since 1989, the largest area of sea ice in Bohai was about 21,800 square kilometers in 2010. In the past 25 years, the average area of Bohai sea ice is approximately 9,200 square kilometers. In the early January of this year, the sea ice area in Bohai reached the highest level, 2.5 times more than the average compared with the same period in the past 25 years. The amplification of the sea ice area is related with the frequent cold air activities. If the cold air continues to affect Bohai seas, the sea ice area may further increase. >> More

The first half of 2012 was cooler and wetter than average, and the second half was warmer and drier than average. The change from wet to dry conditions was consistent with changing sea surface temperatures in the tropical Pacific and Indian Oceans, which are a primary driver of rainfall variability across much of Australia.
The Australian mean rainfall total for 2012 was 476 mm (11 mm above the long-term average of 465 mm); with the year ranked near the median of historical observations. This contrasts with 2011's high annual total of 699 mm. >> More
Go big seemed to be the theme for Mother Nature in 2012 across North America. Super Storm Sandy was said to be the most powerful and biggest Atlantic hurricane in history. But while Sandy was catastrophic for the United States, she was merely a nasty fall storm in Canada; one with a $100 million price tag! The hurricane was a blockbuster in what was another active season. Oddly, it was the third consecutive year that 19 tropical storms developed in the Atlantic basin, which is nearly double the norm. Across Canada, big storms and floods dominated the landscape from January to December leading to mega-buck losses for businesses, governments and thousands of Canadians. Insurers were hit hard by the wicked weather in 2012, facing more than $1 billion in payouts in three of the past four years – an unprecedented and worrisome trend for the industry. >> More
Après une année 2011 chaude et sèche, l'année 2012 a été, globalement sur la France, proche de la normale qu'il s'agisse des températures, des précipitations ou de l'ensoleillement.
Légèrement inférieure à la normale* localement sur la façade ouest du pays et le piémont pyrénéen, la température moyenne est supérieure dans le Sud-Est, en Corse, ainsi qu'en Alsace et en Lorraine. Ce contraste géographique est encore plus marqué en ce qui concerne les températures maximales. Seuls les mois de février, d'avril et de juillet ont été plus froids que la normale. Néanmoins, la température moyenne annuelle en 2012 est proche de la normale*.
La pluviométrie en 2012 est marquée par de fortes disparités régionales. Globalement déficitaires dans le Sud-Ouest, le Languedoc-Roussillon et la basse vallée du Rhône, les cumuls de précipitations sont excédentaires du Nord - Pas-de-Calais au Cotentin, sur l’est des Pays de la Loire ainsi que des départements du Rhône et de la Saône-et-Loire au massif du Jura.
