The Yak-42D plane laboratory "Roshydromet" presentation was held
Posted 20 December 2013

A plane-laboratory was created in Russia for the first time during the last quarter of the century. Many important persons took part in the opening ceremony: Adviser of the Russian President on climate problems Alexander Bedritsky, Adviser of Russian President academician of the Russian Academy of Sciences Mikhail Zalikhanov, Minister of Natural Resources and Environmental Protection Sergey Donskoy, head of Roshydromet Alexander Frolov, executive vice-president of United Aircraft Corporation Alexander Tulyakov, deputy head of Federal Space Agency Anatoly Shilov, and also representatives of the Military-industrial commission, Ministry of Defence of Russia, Emercom of Russia, etc.

"It’s impossible to solve any ecological problem without high-quality monitoring, it was much spoken about this at the Congress on environmental protection which finished its work a few days ago. And this week we received a flying laboratory of very high quality, which enables, to measure so many parameters that there is no spacecraft able to register them all — such an appraisal gave the Minister of Natural Resources and Environmental Protection of the Russian Federation Sergey Donskoy explaining the value of the technical novelty. >> More

 

Canada's Top Ten Weather Stories for 2013 (Environment Canada)
Posted 20 December 2013

Floods were the big newsmakers in Canada in 2013. In some cases it was fast and furious rains that were to blame; in others it was a mix of rainfall and snowmelt. Add an urban landscape with little capacity to absorb the aftermath and you have all the key ingredients for an ominous overflow. The biggest flood hit in June when torrential downpours overwhelmed Calgary and vast areas of southern Alberta forcing 100,000 Albertans from their homes and causing billions of dollars in damages. Three weeks later, large parts of Toronto’s core were flooded by one of the heaviest one-day rainfalls in the city’s history. Canadians were wowed by images of the immediate and powerful forces of nature on our streets and in our backyards. According to the Insurance Bureau of Canada, those two events constitute the first and third largest natural insured catastrophes in Canadian history.  Worth noting is nature’s apparent interest in Calgary. This year’s flooding made it the fourth year in a row that violent weather struck the city hard. Last year, as it was in 2010, a monstrous hailer inflicted multi-million dollar property losses. In 2011, powerful Chinook winds ripped through the downtown at hurricane-force speeds, causing millions more in damages. >> More

 

River flooding could increase under climate change (UK MetOffice)
Posted 20 December 2013

River floods are likely to occur more frequently in many parts of the world as climate change intensifies heavy rainfall, according to a new study. Published today,  the study is the first to use both climate models and river flow simulations from multiple hydrological models to look at global-scale changes in flood hazard under climate change. Using a high-end greenhouse gas emissions scenario out to the end of this century, researchers looked at potential changes in 1 in 30 year peak river flows. Results suggest that while decreases in extreme river flows are likely at about a third of the global land mass, increases are expected at more than half of the areas looked at. At between 5% and 30% of places, 1 in 30 year events became as frequent as 1 in 5 years. >> More

Benefits of weather services much greater than costs (Finnish Meteorological Institute)
Posted 20 December 2013

Kuva: Eija Vallinheimo Kuva: Eija Vallinheimo

The ratio between the costs and benefits of weather services are currently being studied in several countries. In all countries, the results are positive in terms of the social productivity of weather services.


The lowest reported ratio is 2 in the United States, which in this case means that the benefits of the services are double the cost of producing them. On the other hand, typical results were obtained in Switzerland and Finland, where the cost-benefit ratio for weather services intended for road traffic is approximately 10. In order to avoid an overly optimistic result, the Finnish study also took into account costs other than those for weather services, such as the production and operating costs for various media.

The weather in Germany in autumn 2013 - Overall a warm but wet autumn with little sunshine (DWD)
Posted 19 December 2013

After a warm, dry summer with plenty of sunshine, it was unfortunate that high pressure systems only determined the weather for periods of a few days in autumn 2013. A conventional “Indian summer” largely failed to materialise. Instead, mostly low pressure systems brought changeable weather to Germany. Significant weather events were the relatively early and severe first wintry spell in the Alps and the foothills of the Alps on 11 October and, naturally, the windstorm “Christian”, which raged on 28 October with wind speeds as high as 170 km/h, primarily along the North Sea coast. This is what the initial analysis by the Deutscher Wetterdienst (DWD) of data from its around 2,000 weather stations shows. >> More

The weather in Germany in November (DWD)
Posted 19 December 2013

November 2013 initially saw powerful air flows from the west over central Europe, with numerous low pressure areas moving over Germany. Consequently, the air masses were generally mild and caused frequent periods of rain. In the second third of the month, the low pressure areas took a more northerly route and Germany came under the influence of high pressure areas. As is usual for the time of the year, this often caused fog and low stratus cloud. In the last third of the month, the weather alternated between mild and colder weather and wet and dry days. Overall, it was a mild and relatively wet November with little sunshine, as the initial analysis by the Deutscher Wetterdienst (DWD) of data from its around 2,000 weather stations shows. >> More

Torrential rainfall a common climate feature in the future (SMHI)
Posted 19 December 2013

Changes in the climate are expected to result in heavier rainfall. Calculations with climate models show that a heavy downpour will give 20-30 per cent more rain at the turn of the next century.

Thunder showers and torrential rainfall in the summer are part of what, in technical jargon, is called extreme or intensive short-term precipitation.

“Intensive short-term precipitation is the type of rain that causes most problems in towns and cities in connection with runoff and flooding, since it produces large quantities of rain in a short period of time,” says Jonas Olsson, who is a researcher in hydrology at the Swedish Meteorological and Hydrological Institute, SMHI. >> More

FODAS system to be extended to use in the whole country(China Meteorological Admninistration)
Posted 5 December 2013

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

 

Tropical Pacific expected to remain ENSO-neutral this summer (Bureau of Meteorology, Australian Government)
Posted 22 November 2013

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

Climate change produces multiple effects to China (Chinese Meteorological Administration)
Posted 18 November 2013

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

 

Interview with Co-chair of WGI Qin Dahe and Thomas Stocker (Chinese Meteorological Administration)
Posted 18 November 2013

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

CMA: Dr. Qin Dahe awarded the Volvo Environment Prize 2013
Posted 24 October 2013

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

Met Office shows new water leakage model
Posted 24 October 2013

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. >> More

Bureau of Meteorology Australia: Tropical Cyclone Outlook released
Posted 24 October 2013

The tropical cyclone Australian regionsThe 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

Forecast Outlook for 2013 NE Monsoon Season (October–December)
Rainfall over South Peninsula
Posted 24 October 2013

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.

Singapore Affected by Severe Transboundary Smoke Haze in June 2013
Posted 20 September 2013

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

Better infrastructure for continued development of climate models(SMHI)
Posted 13 September 2013

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

Tropical Pacific and Indian oceans both neutral (Australian Bureau of Meteorology)
Posted 13 September 2013

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

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.sunshine over fields

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. >> More

La influencia del anticiclón del Atlántico disminuye considerablemente con respecto a julio y agosto, lo que, unido al paso frecuente de las ondas y las bajas tropicales, propicia el incremento de las precipitaciones. Septiembre es también el mes de mayor frecuencia de formación de ciclones tropicales en nuestra región, por lo que se incrementa la actividad ciclónica sobre Cuba de forma notable con respecto a agosto, aunque la frecuencia de los huracanes que la afectan en dicho mes es algo inferior a octubre. Asociados a la influencia directa o indirecta de los ciclones tropicales, en septiembre suelen ocurrir eventos de grandes precipitaciones.

En el presente septiembre se espera que ocurran totales de precipitación cercanos o por encima del intervalo considerado como normal en todas las regiones del país, (tabla 1). 

De forma habitual, en septiembre se mantienen las condiciones de intenso calor propias del verano en Cuba; aunque la temperatura desciende ligeramente con respecto a agosto. Los altos valores de humedad relativa reinantes y el predominio de vientos débiles en la mayor parte del territorio nacional conllevan a la persistencia de sensaciones calurosas y muy calurosas en el ser humano. Desde 1981 septiembre ha sido más caluroso que lo normal en la mayor parte de los años. En esta ocasión se prevé un mes muy cálido, con temperaturas máximas y mínimas cercanas o por encima de lo normal en todas las regiones del país, (tabla 2). >> More

 

NOAA: July global temperatures sixth highest on record
Posted 20 August 2013

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. >>More

 

NOAA: Atlantic hurricane season on track to be above-normal
Posted 20 August 2013

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. >>More

Review of the Australia Bureau of Meteorology's extreme weather and seasonal forecasting capacity
Posted 20 August 2013Abstract graphic with title

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.

PAGASA (Philippines) Seasonal Climate Outlook July-Dec 2013
Posted 20 August 2013

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. >>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

 

Tropical cyclone damages in China under global warming (China Meteorological Administration)
Posted 29 July 2013

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

Better infrastructure for continued development of climate models (SMHI)
Posted 29 July 2013

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

A new research programme to achieve an improved understanding of the Earth system for the Baltic Sea region (Swedish Meteorological and Hydrological Institute)
Posted 13 June 2013

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

Predicción climática mensual de totales de precipitación y temperaturas medias extremas del territorio de Cuba para junio del 2013 (INSMET, Republica de Cuba)
Posted 11 June 2013

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. Para el actual junio se prevén temperaturas altas, con máximas cercanas a lo habitual en esta época del año y mínimas cercanas o superiores a lo normal. >> Mas

 

Mayo, el más frío desde 1985 y algo más seco (AEMet)

Ocean acidification in the western North Pacific (Japan Meteorological Agency)
Posted 11 June 2013

pH at 10,20,30N at 137E

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

 

Coldest spring for more than 50 years (MetOffice)
Posted 11 June 2013

Spring sunshine

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.

That would make this the 5th coldest spring in national records dating back to 1910 and the coldest spring since 1962. >> More

Radarsatellitbild från TerraSAR-X den 6 maj 2013, islossning

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

Satellite measurements show hidden water content of snow
Posted 13 May 2013

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

Un nouveau rapport révèle les conséquences du changement climatique en Suisse(MétéoSuisse)
Posted 12 April 2013

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

Satellite data provide insight into melting Arctic ice (SMHI, Sweden)
Posted 10 April 2013

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.

Meteorological conditions

Three changes in the meteorological conditions were likely important factors in the low ice spread: 

  • Ice did not build up as much as normal during the winter and early spring of 2012, as the ice zones in the Euro-Asiatic and North Atlantic areas were warmer than normal.
  • Ocean circulation patterns meant that more ice than normal was carried from the Arctic to the Atlantic Ocean during the spring and early summer of 2012.
  • Warming over the Canadian archipelago and the south-east Beaufort Sea north of Alaska from May and over summer 2012 was probably also a factor. >> More

© Météo-France © Météo-France

Après un hiver maussade, tout particulièrement sur la moitié Nord du pays, le mois de mars s’est révélé agité, plus froid et moins ensoleillé que la normale. Seul le Sud-Ouest, un peu moins soumis aux différentes intempéries, a bénéficié d’un ensoleillement et de températures proches des valeurs attendues pour un mois de mars. 

De nombreux passages perturbés se sont succédé au cours du mois et n’ont guère laissé le soleil percer durablement. L’ensoleillement a été faible sur la majeure partie du territoire, notamment sur le Nord-Ouest où il est déficitaire de plus de 30% ainsi que sur le Nord-Est du pays et sur la Corse. 

Sur l’ensemble du mois, les températures ont été particulièrement froides pour la saison de la Bretagne aux frontières du Nord et du Nord-Est où elles sont inférieures de 1 à 3 °C aux normales.  Un épisode hivernal tardif est survenu en milieu de mois et a concerné la quasi-totalité du pays. >> suite

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

NOAA: February Global Temperatures Ninth Highest on Record
Posted 14 March 2013

According to NOAA scientists, the globally-averaged temperature for February 2013 tied with 2003 as the ninth warmest February since record keeping began in 1880. It also marked the 28th consecutive February and 336th consecutive month with a global temperature above the 20th century average. The last below-average February temperature and the last below-average temperature for any month was February 1985.

Many areas of the world experienced higher-than-average monthly temperatures, including eastern Europe, western Russia, the Middle East, much of Canada, and southern Greenland. Meanwhile, northern and western Alaska, far northwestern Canada, a large swath of the contiguous United States, western Europe, northwestern Africa, Siberia, Mongolia, and most of the eastern Pacific Ocean were notably below average.

February was markedly milder than normally. The statistics compiled by the Finnish Meteorological Institute show that the most significant feature for the whole winter was the cloudy weather type. The number of sunshine hours measured was the lowest for the past 50 years.

According to the Finnish Meteorological Institute, the mean temperature for February ranged from about -2° C on the west coast to about -10° C in some areas of Northern Lapland. Seen against the long-term average, February was milder than normally in the whole of Finland

The greatest difference, or about five degrees Celsius, was measured in the easternmost areas of Finland, and the smallest difference, 1–2 degrees, in Enontekiö and in the northernmost Lapland. The lowest temperature for the month was -34.0° C, recorded in Kevojärvi, Utsjoki on 7 February. The highest temperature was 8.0° C, measured in Jomala, in the Åland Islands, on 27 February. >> More

On 4 February, the Finnish Meteorological Institute started year-round aerosol and greenhouse gas measurements in Antarctica, at the Marambio research station maintained by Argentina. The measurements are used to study the progression of climate change, its causes and consequences.

Measurements of aerosols and greenhouse gases in Antarctica provide a comprehensive and highly interesting addition to research conducted in the cold polar regions. They contribute significantly to the monitoring of the extent and impacts of climate change. No equally comprehensive year-round measurements have been conducted on the Antarctic Peninsula before. Thus, they may also reveal new, unpredictable phenomena and processes. >> More

 

NOAA: Contiguous U.S. warmer and wetter than average for winter season
Posted 13 March 2013

According to NOAA scientists, the average temperature for the contiguous U.S. during the winter season (December 2012 - February 2013) was 34.3°F, 1.9°F above the 20th century average, marking the 20th warmest winter on record. The February temperature for the contiguous U.S. was 34.8°F, 0.8°F above average.

The total winter precipitation averaged across the contiguous United States was 7.10 inches and this was 0.63 inches above the 20th century average.  February contributed 2.00 inches to this total, which was near the long-term average.  During February, several winter storms impacted the nation, improving drought conditions across the Southeast and Midwest, but lighter precipitation totals across the Central Plains and Mountain West provided little drought relief. >> More

Neutral ENSO state persists in tropical Pacific (Bureau of Meteorology, Australia)
Posted 13 March 2013

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.

The Indian Ocean Dipole (IOD) has little influence upon Australia’s climate from December through to April. >> More

Higher temperatures affect intensive rain showers
Posted 27 February 2013

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

 

Human influence on East Africa drought
Posted 25 February 2013

Africa drought

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

 

NOAA: January global temperatures ninth highest on record
Posted 25 February 2013

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.

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

 

Zimbabwe prepared to Deal with the adverse effects of Climate Change - An introspection of Zimbabwe’s Adaptive Capacity (Meteorological Services Department of Zimbabwe)
Posted 21 February 2013

news

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

probability of exceeding median rainfall - click on the map for a larger version of the map

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.

The Russian meteorologists take part in international aviation exercise on
responding to volcanic eruptions

Posted 14 February 2013

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

 

Prévoir la rigueur de l'hiver en Europe sur la base de l'enneigement automnal en
Sibérie?
(MétéoFrance)
Posted 12 February 2013

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

Special Climate Statement 44 – extreme rainfall and flooding in coastal Queensland
and New South Wales (Australian Government - Bureau of Meteorology)
Posted 7 February 2013

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

CMA revises haze warning standard taking PM2.5 as quota
Posted 31 January 2013

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). >> More

NOAA deploys high-tech plane to improve winter storm forecasts
Posted 28 January 2013

 

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. >> More

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

The Year's Weather - 2012 - Hong Kong Observatory
Posted 17 January 2013

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[1] 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. >> More

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

 

Review of the year: The weather in Germany in 2012 (DWD)
Posted 15 January 2013

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

Record breaking heatwave to continue this week (Bureau of Meteorology, Australian Government)
Posted 15 January 2013

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

Sea ice coverage in Bohai reaches the maximum in the same period over 25 years (China Meteorological Administration )
Posted 15 January 2013

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

2012 Australian rainfall deciles map

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

 

Canada's Top Ten Weather Stories for 2012 (Environment Canada )
Posted 7 January 2013

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

 

Bilan de l’année 2012 (MeteoFrance)
Posted 7 January 2013

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. Cumulée sur l'ensemble du pays, la quantité d'eau recueillie est toutefois conforme à la valeur moyenne. >> Suite
