Preliminary Info on 2012 U.S. Billion-Dollar Extreme Weather/Climate Events (NOAA, U.S.A. )
Today, NOAA released preliminary information on extreme weather and climate events in the U.S. for 2012 that are known to have reached the $1 billion threshold in losses. As of December 20, NOAA estimates that the nation experienced 11 such events, to include seven severe weather/tornado events, two tropical storm/hurricane events, and the yearlong drought and associated wildfires.
These eleven events combined are believed to have caused 349 deaths, with the most significant losses of life occurring during Sandy (131) and the summer-long heat wave and associated drought, which caused over 123 direct deaths (though an estimate of the excess mortality due to heat stress is still unknown). >> More
The properties and distribution of clouds around the globe are important to climate research. There is now a 28-year compilation of clouds and radiation – a cloud climatology – based on data from polar satellites.
The Earth’s climate is largely determined by incoming solar radiation. Clouds help to reflect some of the radiation away.
“Roughly 30 per cent of the sun’s radiation is reflected away from the Earth, and most of that radiation is reflected away by clouds. Less than 10 per cent of the total radiation is reflected by the Earth’s surface,” says Karl-Göran Karlsson, a remote analysis scientist at SMHI and one of the people taking part in the project. >> More
A changing climate places great pressure on society, and creates many new challenges. To make city planning easier, a planning tool has been developed to support climate adaptation of cities and regions in Europe.
The European research project SUDPLAN, co-ordinated by SMHI, has developed a planning tool for climate adaptation of European cities and regions for intensive precipitation, hydrological conditions and the air environment.
“Already today we are beginning to notice climate-related problems in cities, such as flooding. As the climate changes even more, these difficulties will increase. This is why a tool is needed to facilitate planning ahead of decisions regarding investments in infrastructure, for instance, and to ensure that projects are adapted to the altered conditions we will be facing in the future,” says Lars Gidhagen, researcher in air quality at SMHI and co-ordinator of SUDPLAN. >> More
The tropical Pacific Ocean remains neutral—neither El Niño nor La Niña. The central to eastern Pacific has cooled somewhat over the past month, with sea surface temperatures (SSTs) now close to their long-term average. Atmospheric indicators of ENSO, such as the Southern Oscillation Index (SOI), trade winds and cloudiness near the Date Line have shown some fluctuations recently, but have also continued at neutral levels. Further falls are expected in the SOI over the coming days, as a result of the tropical weather system which spawned Tropical Cyclone Evan. Large fluctuations in the SOI over summer due to tropical weather systems are not uncommon.
Climate models surveyed by the Bureau of Meteorology indicate that the tropical Pacific is likely to remain ENSO neutral through the southern hemisphere summer. This means that in contrast to the two prior summers, Australian rainfall and temperatures are unlikely to be strongly influenced by ENSO. Given current conditions and outlooks, this will be the first ENSO-neutral summer since 2005–06.
The influence of the Indian Ocean Dipole (IOD) on Australian rainfall is limited during summer and autumn, though near-record ocean temperatures off the northwest Australian coast may have at least a local influence. >> More
En la importante disminución del ozono estratosférico sobre la Antártida
durante la primavera austral (fenómeno conocido como “agujero de
ozono”), desde hace ya algunos años se registra una mejoría. Existen
evidencias de un retroceso gradual del daño en dicha capa de ozono. La
recuperación gradual de la capa de ozono significa una reducción en los
casos de cáncer de piel y cataratas en la población del hemisferio Sur.
La recuperación es posible debido a la reducción en la emisión de
sustancias químicas destructoras del ozono que son liberadas por la
humanidad (mandato del Protocolo de Montreal en 1987).
Este año, el "agujero de ozono" fue mucho menor, ya que las
fluctuaciones naturales en los patrones del clima produjeron una
estratosfera más cálida que en los últimos años. Este aumento de la
temperatura ha retrasado el desarrollo de las Nubes Estratosféricas Polares, que es donde se producen las reacciones químicas que están implicadas en la destrucción del ozono y que conduce al “agujero de ozono”.
Si bien el agotamiento de este año ha tenido una gran reducción, la variación en los patrones del clima son tales que en el futuro tendremos más destrucción que la que hubo durante este año. El retorno a que los niveles de ozono sean casi normales durante la primavera austral es lento, se espera que la recuperación se complete recién después de 2040. Los valiosos datos obtenidos en las estaciones de monitoreo de ozono con base en tierra Marambio y Ushuaia de Argentina, han sido utilizadas para verificar los datos de los satélites y los informes proporcionados por la agencia espacial de EE.UU. (NASA) y el Servicio Meteorológico de EE.UU. (NOAA). http://www.smn.gov.ar/
A deep surface trough interacted with a slow moving middle level low off the Western Australian west coast to produce widespread showers and thunderstorms across most of Western Australia from 10 to 13 December 2012. The middle level low was both slow moving, allowing moisture to build up over southwest Western Australia over a period of several days, and in phase with the surface trough, enhancing atmospheric instability. These factors combined to produce unusually heavy rainfall in southwest Western Australia over several days. >> More

Arctic sea ice reached record-breaking low extents during summer 2012, weeks before the end of the melt season. The previous record for the pan-Arctic sea ice minimum extent was set in September 2007 (4.2 million km2). That record was nearly broken in September 2011, when the sea ice extent shrank to 4.6 million km2. In mid-September 2012, the minimum extent reached 3.41 million km2, a new pan-Arctic sea ice minimum extent (based on the NSIDC 1979-2012 satellite record - source: NSIDC). >> More
Climate scientists from the National Meteorological Services within the Southern Africa Development Community (SADC) region, including Malawi, met from 13th to 22nd August 2012 in Harare, Zimbabwe. The aim of the meeting was to come up with a consensus forecast for the 2012/2013 rainfall season for the SADC region. This was presented to users at the Sixteenth Southern Africa Regional Climate Outlook Forum (SARCOF-16) which took place from 23rd to 24th August 2012 at the same venue.

Shanghai Xujiahui Observatory, a multi-functional observatory was established in 1872. It has been called “the No.1 meteorological observatory in the Far East” at that time and has played a significant role in the international meteorological history. Xujiahui Observatory also has been highly praised by the international community.
Shanghai Xujiahui Observatory witnessed the Chinese modern meteorological history. It gives us lots of precious data such as the meteorological building with history of over 100 years and the unique style. Its scientific and cultural values are of great importance. Xujiahui Observatory started to observe weather from December, 1872. In 1879, it issued typhoon forecast for the 1st time. In 1882, it released weather forecast in both Chinese and English newspaper which included not only Chinese meteorological report, but also report for northern and southwestern Asia. In 1884, the signal tower in the bund in Shanghai was built. In 1895, China's 1st surface weather map for East Asia was produced there. In the end of the 19th century, its contact network reached Siberia in the north, Manila in the south, Japan in the east and India Peninsular in the west. Meanwhile, Xujiahui Observatory also released weather information for the meteorological observatories in Chinese coastal areas and sailing ships and gained gratefulness of navigators for the meteorological report. From March 1 of 1920, after releasing daily weather report by radio, Xujiahui Observatory started to release upper air conditions at 11:00 and 17:00 every day. >> More
November 30 marks the end of the 2012 Atlantic Hurricane season, one that produced 19 named storms, of which 10 became hurricanes and one became a major hurricane. The number of named storms is well above the average of 12. The number of hurricanes is also above the average of six, but the number of major hurricanes is below the average of three.
Based on the combined number, intensity, and duration of all tropical storms and hurricanes, NOAA classifies the season as above-normal. 2012 was an active year, but not exceptionally so as there were 10 busier years in the last three decades. >> More

One of the most significant spring heatwaves on record affected large parts of eastern
Australia in the last week of November 2012. Temperatures reached levels not
previously observed at this time of year in many areas, particularly in northern Victoria
and southern inland New South Wales, and a record was set for the highest spring
temperature on record in Victoria.
The event started with a build-up of extreme heat in central Australia over the weekend of 24-25 November. This was the latest of a sequence of extreme heat events in the region over the course of spring 2012 which was the hottest on record for average maximum temperatures over much of outback South Australia. The first day over 45 °C for the event occurred on 25 November, when Oodnadatta reached 45.6 °C, and temperatures remained in the low to mid-40s in northern South Australia, and adjacent parts of Queensland and New South Wales, for the next three days. Marree Airport in South Australia reached 45.5 °C on the 26th and 44.1 °C on the 28th. >> More
Upper Thailand December and January, high pressure area from China will extend its ridge to cover the
upper Thailand, mainly stronger more continuously. Consequently, the temperature will become cool or cold

Before there were satellites, weather data transmitters, or computer databases, there were the ship’s logs of Arctic sea voyages, where sailors dutifully recording weather observations. Now, a new crowdsourcing effort could soon make of the weather data from these ship logs, some more than 150 years old, available to climate scientists worldwide.
NOAA, National Archives and Records Administration, Zooniverse—a citizen science web portal—and other partners are seeking volunteers to transcribe a newly digitized set of ship logs dating to 1850. The ship logs, preserved by NARA, are from U.S. Navy, Coast Guard and Revenue Cutter voyages in the Arctic between 1850 and the World War II era. >> More

The western half of the continental U.S. and central and northern Alaska could be in for a warmer-than-average winter, while most of Florida might be colder-than-normal December through February, according to NOAA’s annual Winter Outlook announced today from the agency’s new Center for Weather and Climate Prediction in College Park, Md.
Forecasters with NOAA’s Climate Prediction Center say a wavering El Niño, expected to have developed by now, makes this year’s winter outlook less certain than previous years.
The month of September 2012 has brought with it exceptionally low rainfall amounts this year which has shattered records for the two manned meteorological stations on the island. The Canefield Airport on the south-west coast and the Melville Hall Airport on the north-east coast has been recording data for the past 30 years and 41 years, respectively.
September, notably the wettest month at the Canefield station, has been the driest month for 2012 thus far with a rainfall accumulation of 31.9 mm - a mere Thirteen (13) percent of the monthly average total of 253.7 mm. The Canefield station was greeted with a ten- day dry spell which began on the first (01st) and ended on the tenth (10th). The maximum daily total was 18.5mm, which occurred on the 26th during a period when the area was affected by a low level trough. In total, twenty-four (24) dry days were experienced, that is, eleven (11) more days than the mean number of dry days. The month was generally warmer, recording 0.7° Celsius greater than the monthly average which is 29.4°Celsius.

A cette fin, ce « South West Indian Ocean Climate Outlook Forum » (SWIOCOF) va réunir des météorologues des pays membres de la Commission de l’océan Indien (Comores, Madagascar, Maurice, La Réunion/France, Seychelles), des responsables de secteurs sensibles aux aléas climatiques (environnement, pêche, santé, prévention des risques naturels), et des observateurs de pays limitrophes (Tanzanie, SADC, Sri Lanka, Inde). Il est précédé d'un pré-forum, à destination des climatologues, du 24 au 28 septembre. >> suite
Japan Meteorological Agency launches new English-language contents: State of the Ocean Climate with details on sea surface temperature (global), sea surface temperature (around Japan), global ocean heat content, sea level (around Japan), sea ice in Arctic and Antarctic areas, sea ice in the Sea of Okhotsk ; and Ocean Carbon Cycle with details on annual changes in oceanic and atmospheric carbon dioxide concentrations in the western north Pacific, carbon dioxide exchange in the Pacific Ocean, and column inventory of oceanic carbon dioxide in the western North Pacific
Le programme international de recherche HyMeX vise à mieux comprendre le cycle de l’eau en Méditerranée afin d’améliorer la prévision des risques hydrométéorologiques et la simulation de leur évolution dans les prochaines décennies. Pluies intenses et crues rapides, vents violents et sécheresses affectent en effet sévèrement tout le pourtour méditerranéen.
Coordonné par Météo-France et le CNRS, HyMeX rassemble près de 400 scientifiques d’une vingtaine de pays. La première campagne de mesures intensives se déroulera du 5 septembre au 6 novembre 2012. L’objectif : collecter le maximum de données sur toute la Méditerranée nord-occidentale, en France, en Italie et en Espagne.
On September 14-17, delegates from Environment Canada paid visits to Jiangsu and Shanghai meteorological departments, accompanied by CMA Deputy Administrator Shen Xiaonong. The delegation was led by Mr. David Grimes, the President of WMO, Assistant Deputy Minister and Head of Environment Canada's Meteorological Service.
In Jiangsu the visiting delegation investigated the construction of meteorological modernization, addressing climate change, decision-making & public meteorological services.
Temperature anomalies and percentiles are shown on the gridded maps below. The anomaly map on the left is a product of a merged land surface temperature (Global Historical Climatology Network, GHCN) and sea surface temperature (ERSST.v3b) anomaly analysis developed by Smith et al. (2008). Temperature anomalies for land and ocean are analyzed separately and then merged to form the global analysis. For more information, please visit NCDC's Global Surface Temperature Anomalies page. The August 2012 Global State of the Climate report introduces percentile maps that complement the information provided by the anomaly maps. These new maps on the right provide additional information by placing the temperature anomaly observed for a specific place and time period into historical perspective, showing how the most current month, season or year compares with the past.
Renowned water scientist Dr Rob Vertessy has been appointed director of Australia’s Bureau of Meteorology, Senator Don Farrell, Parliamentary Secretary for Sustainability and Urban Water, announced today.
Dr Vertessy, who was appointed Deputy Director of the Bureau (Climate and Water) in 2007, has been acting as Director since December last year.
Highlights of the last week:
Monsoon trough remained active and south of its normal position during most days of the week resulting active to vigorous monsoon conditions over the parts of central India, south Peninsula and northwest India during many days of the week.
The country as a whole received above normal rainfall on most days of the week.
Seasonal rainfall country as a whole further improved by 2% as compared to previous week.
According to NOAA scientists, the average temperature for the contiguous U.S. during August was 74.4°F, 1.6°F above the long-term average, marking the 16th warmest August on record. The warmer-than-average August, in combination with the hottest July and a warmer-than-average June, contributed to the third hottest summer on record since recordkeeping began in 1895.
The summer season's (June-August) nationally-averaged temperature was 74.4°F, 2.3°F above the 20th century average. Only the summers of 2011 (74.5°F) and 1936 (74.6°F) had higher temperatures for the Lower 48.
The August nationally-averaged precipitation total of 2.59 inches was near the long-term average. The Southwest and Southeast were wetter than average and the Northwest and the Northern Plains were drier than average. As of August 28th, according to the U.S. Drought Monitor, nearly 63 percent of the contiguous U.S. continued to experience drought conditions.
To further enhance personalized weather services, the Observatory launched on a trial basis the "Location-based Rain Forecast" on the mobile app "MyObservatory". Users can now easily get hold of the rainfall forecast in the coming two hours specific to their actual or selected location. The service is made available on the "MyObservatory" on both the iPhone/iPad platform (version 4.0) and the Android platform (version 3.0).
The trial "Location-based Rain Forecast" is generated automatically by computer without any manual adjustment. The main purpose is to enable users to receive as soon as possible the latest rainfall prediction for their reference, so as to help them better arrange their daily activities or plan outdoor activities.
The personalized weather service "MyObservatory" has been well-received since its launch in March 2010. The total number of page views has exceeded 6.4 billion by August 2012.
The climate outlook for the 2012 "Short Rains" (October, November, December) indicates that much of the country is likely to experience enhanced rainfall. This will be driven mainly by the warming of the Sea Surface Temperures (SSTs) in the Western Equatorial Indian Ocean adjacent to the East African coastline, coupled with cooler than avearge SSTs in the Eastern Equatorial Indian Ocean adjacent to Australia (the so-called positive Indian Ocean Dipole. The distribution of rainfall in time and space is expected to be generally good.
Las lluvias a nivel nacional se mantendrán muy cerca de su promedio histórico a lo
largo de septiembre y octubre, pero durante noviembre se prevé una considerable
reducción en comparación con el promedio histórico, sobre todo en el occidente y
el litoral del Océano Pacífico, de acuerdo con el análisis del Servicio Meteorológico
Durante agosto el promedio de precipitación nacional rebasó en 19 por ciento la
cifra que históricamente se observa en ese mes, de 138.9 milímetros (mm), al
ubicarse en 164.8 mm. Esto se debió principalmente a la presencia de varios
ciclones y ondas tropicales tanto en el Pacífico como en el Atlántico, algunos de
los cuales generaron cantidades importantes de precipitaciones en el país.
05/09/2012 Agosto ha sido extremadamente cálido, con una media de 25,4 ºC que supera en 2,0 ºC el valor normal y se convierte en el segundo mes de agosto más cálido de la serie histórica. En cuanto a precipitaciones, este mes ha resultado muy seco, con una media de 9 mm que supone poco más de la tercera parte del valor medio, siendo el tercer mes de agosto más seco desde 1961
A lo largo del mes de agosto predominó la circulación zonal alta, de verano, en el Atlántico norte, con una dorsal suave sobre el oeste de Europa y embolsamiento de aire cálido sobre la Península y el Mediterráneo occidental. En superficie, los sistemas de bajas presiones que se formaron en latitudes altas apenas llegaron a afectar a algo más que la costa Cantábrica, mientras que el resto de la Península y las Baleares se mantuvieron con un aire estable y en calma.
The mean temperature of August was higher than the normal years. Some places suffered heat wave. As for the precipitation, it was less than the normal years while different places had different conditions. The coastal area of eastern China suffered regional extreme rainfall.
In August, the mean temperature of China was 21.4℃, 0.5℃ higher than the normal 20.9℃. In August, east part of Southwest China and the coastal area of southeast China suffered 18 extreme high temperature events. As for precipitation, the mean precipitation of China was 87.7mm, which was less than the normal years (102.5mm) by 14.4%. Influenced by typhoons, 47 stations of China got extreme continuous rainfall events in Liaoning, Hebei, Shandong and etc.
Experts suggest that September is a transitional month of summer and autumn. Northwest, Northeast and North China are in autumn while south of the Yangtze and South China are still in the flood season. The coastal area of Southeast China should concern the activities of typhoon and strengthen typhoon prevention work. Meanwhile, cold air will intensify in September. So the public people should pay attention to weather change. (Sep 3)
On September 3, Administrator of CMA Zheng Guoguang and other members of the delegation, who was to participate in the 8th session of Sino-Russian meteorological scientific and technological cooperation in Obninsk, visited Russian “typhoon” research and production association and listened to the comprehensive introduction of the working conditions.
Currently, the 8th session of Sino-Russian meteorological scientific and technological cooperation is held in Obninsk, Russia. On behalf of CMA and Russian Federal Service for Hydrometeorology and Environmental Monitoring, Dr. Zheng Guoguang and Dr. Frolov led the delegations to participate in the meeting. The 2 delegations aim to exchange views on the latest developments of Chinese and Russian meteorological departments, review the progresses of the bilateral cooperation projects in the past 2 years and discuss the future cooperative projects and fields in the coming 2 years.
David Molden, Director General, and Eklabaya Sharma, Director, Programme Operations, of the International Centre for Integrated Mountain Development (ICIMOD) visited the Finnish Meteorological Institute on 29 August. The visit was prompted by more extensive cooperation between the Meteorological Institute and ICIMOD.
On 29 August 2012, the Finnish Meteorological Institute and ICIMOD signed a Memorandum of Understanding that will intensify cooperation aimed at enhancing hydrometeorological knowledge and preparation for natural disasters in the Himalayan region. The Memorandum of Understanding creates a formal framework for cooperation between the two organisations
La France a connu cette année un début d'été maussade sur de nombreuses régions, très humide sur la moitié nord en juin et frais sur l'ensemble du pays en juillet. Les conditions se sont ensuite sensiblement améliorées avec un mois d'août sec, chaud et ensoleillé.
Après un mois de juin contrasté, plutôt frais sur le nord-ouest du pays mais relativement chaud au sud, le mois de juillet a été frais et le mois d’août chaud sur la plupart des régions. Moyennée sur l’ensemble de l’été, la température a été sensiblement supérieure à la normale sur le Sud-Est, mais proche voire même inférieure à celle-ci sur le Nord-Ouest. Sur l’ensemble du pays, la température moyenne a été supérieure de 0,3 °C à la normale*.
Les précipitations ont été assez contrastées. Suite aux pluies abondantes de juin et juillet, on enregistre des précipitations excédentaires dans le nord-ouest et du nord de la région Rhône-Alpes au sud de l’Alsace. Inversement, elles ont été généralement déficitaires du Sud-Ouest à la Lorraine. Le déficit atteint environ 50% sur le Roussillon et la région Provence-Alpes-Côte-d’Azur, et est encore plus marqué sur la Corse où il dépasse parfois 75 %. Sur l’ensemble de la France, la quantité d’eau recueillie est conforme à la normale*.
L'ensoleillement a été légèrement déficitaire sur le nord du pays, mais plutôt excédentaire sur la moitié sud.
Figures up to the 29 August show that 366.8 mm of rain fell across the UK. It is not expected that rainfall this summer will exceed the 384.4 mm of rain seen in the summer of 1912, which is the wettest.
These latest figures follow a record wet April, and an April to June period that was also the wettest recorded in the UK.
Summer 2012 is also likely to be one of the dullest summers on record with just 399 hours of sunshine up to 28 August. This makes it the dullest summer since 1980 when the UK saw only 396 hours of sunshine.
To complete the disappointing picture, it has also been a relatively cool summer with a mean temperature of 14.0 °C, some 0.4 °C below the long term average. Despite this it was a little warmer than the summer of 2011 which saw a mean temperature of only 13.7 °C.
Du 30 Août au 01 septembre 2012, une perturbation a donné 40 à 80 mm de précipitations dans les Alpes et les Préalpes, localement les 90 à 100mm ont été atteint par barrage sur le versant nord des Alpes.
La perturbation Atlantique, qui dans un premier temps a traversé d'ouest en est nos régions, et ensuite revenues par l'est dans un courant de bise (situation de retour d'est, appelée aussi "bise noire").
Le passage de cette perturbation s'est accompagné d'un courant du nord à nord-est, d'une baisse des températures et de la limite des chutes de neige, généralement vers 2000m , parfois en-dessous de 1700m dans l'est dans les zones de barrage.
Due to presence of low pressure area and other embedded vortices, the
monsoon trough remained active on most days of the last week, which caused
active to vigorous monsoon conditions over parts of northwest India and south
This week received the highest all India rainfall of this monsoon season so far
that is 6% above long period average (LPA). As a result, seasonal rainfall country
as a whole further improved by 2% as compared to previous week. For the country as a whole, seasonal rainfall upto 29 August 2012 was 12% below the LPA as against 14% by the end of last week ending 22nd August.
Pakistan Meteorological Department (PMD) and Agency for Technical Cooperation & Development (ACTED) signed a Framework for cooperation to develop & implement GIS-enabled Meteorological Information System. This would help end users for effective response and timely mitigation measures in case any natural hazard is likely to affect vulnerable communities.The GIS enabled web tools will ingest near real-time meteorological data and products and would help in vulnerability assessment of locations along with population density which is the critical information for effective response system.
El próximo 25 de septiembre se abrirá la exposición conmemorativa del 125 Aniversario de la creación del Servicio Meteorológico Español en el Centro Cultural del Ayuntamiento de Boadilla del Monte (Madrid), situado en la calle Isabel de Farnesio, 16. Permanecerá abierta hasta el 31 de diciembre.
Durante la muestra se celebrarán dos reuniones: La “X Cimhet”, de directores de los Servicios Meteorológicos e Hidrológicos Iberoamericanos; y la “V Afrimet”, de directores de los Servicios Meteorológicos e Hidrológicos Nacionales del África del Oeste".
Atmospheric circulation in the tropical Pacific continued to be near-normal in July 2012, although a persistent warming in the tropical Pacific Ocean trending towards an El Nino condition have been observed since June. Warmer sea surface temperature strengthened in the central and eastern equatorial Pacific ocean, a typical development stage of an El Niño. Likewise, observed warmer temperatures below the surface of the entire equatorial Pacific Ocean is a good indicator to sustain the evolving El Nino condition. Dynamical and statistical model forecasts suggest the El Niño will likely develop in August or September.
El Niño periods are usually characterized by below normal rainfall condition across most areas of the country during the last quarter of the year (OND) and early months or first quarter (Jan-Mar) of the following year. Climate pattern in the country during the months of July and August was generally influenced by the moderate to strong westerlies, which reflect an active Southwest (SW) monsoon activity, generating enhanced rainfall over most areas of the country. This characterized the seasonal variability of El Nino impact, where the reverse happened during the early stages of warm episode, an enhanced rainfall in any time within the months of July, August, September instead of below normal rainfall condition.
Tropical Pacific Ocean indicators have remained close to El Niño thresholds over the past fortnight. While tropical Pacific sea surface temperatures and the Southern Oscillation Index (SOI), approached or exceeded El Niño values during the past fortnight, other indicators such as the trade winds and tropical cloud patterns have yet to show typical El Niño signatures.
Regardless of the ENSO state, the tropical Pacific remains warmer than average. This, combined with other influences on Australian climate such as cooler than normal waters to the north of the continent and the patterns of cloud and ocean temperatures in the Indian Ocean, tends to favour below-average rainfall over eastern Australia.
The number of typhoons landing in China in August has exceeded historical extremes so far. Qian Chuanhai, Director of the typhoon and ocean forecast center of CMA, said since the flood season this year, the number of typhoons landing in China is more than normal years. The landing phase is more concentrated and has affected a wider range of areas. Compared to the same period in history, it breaks a number of records.
Firstly, typhoons occurred in higher latitude with a larger number compared with normal years. Currently, the northwest Pacific and the South China Sea have seen 15 typhoons (including tropical storms and higher intensity) and this number is larger than average level (12.8). Typhoons landing on China's northern coast are obviously more than the normal.
La prévision des modèles de MétéoSuisse pour la température automnale 2012 (septembre à novembre).
En Suisse romande, aucune tendance bien claire ne se dessine pour l'automne 2012. Quoiqu'il en soit, un automne normal ou doux semble un peu plus vraisemblable qu'un automne froid.
Pour l'ouest de la Suisse, nous parlons d'un automne plus frais, lorsque la température moyenne automnale se situe en-dessous de 10.4°C. Pour un automne normal, la température moyenne se situera entre 10.4°C et 10.9°C. Et un automne chaud affichera des températures moyennes au-dessus de 10.9°C.
Les deux valeurs limites de températures (10.4°C et 10.9°C) ont été définies sur la base d'une longue série de mesures (depuis 1981) dans laquelle les automnes frais, normaux ou chauds avaient la même occurrence statistique.
Out of 36 meteorological sub-divisions, rainfall was excess/normal in 20, deficient in 11 and scanty in 05 sub-divisions during the week. In area-wise distribution, 62% area of the country received excess/normal rainfall. Remaining 38% area received deficient/scanty rainfall. Meteorological sub-divisionwise rainfall for the week is given in Annexure I and II.
Out of 36 meteorological subdivisions, the rainfall has been excess/normal in 20, deficient in 14 and scanty in 02 sub-divisions (Punjab and Saurashtra & Kutch). In area-wise distribution, 55% area of the country received excess/normal rainfall. Remaining 45% area received deficient/scanty rainfall.

El crecimiento poblacional anárquico dificulta la ejecución de políticas públicas que contribuyan a que los organismos operadores ofrezcan mejores servicios
El ordenamiento territorial ha sido y es el principal reto para mejorar las políticas públicas en materia de agua, pues de la planeación y del respeto a los bosques, las áreas de recarga de acuíferos, las zonas de natural inundación y las aledañas a los ríos, depende, en gran medida, el cumplimiento de metas fundamentales en los rubros de agua potable y drenaje, saneamiento de aguas negras y seguridad de la población frente a los fenómenos hidrometeorológicos, aseveró José Luis Luege Tamargo, Director General de la Comisión Nacional del Agua (Conagua).
Las aguas subterráneas en Colombia constituyen un recurso del subsuelo que día a día adquiere mayor importancia pues se reconoce como alternativa de aprovechamiento en cuencas con limitaciones en el acceso al agua proveniente de fuentes superficiales, y su influencia en obras civiles como túneles y carreteras, proyectos mineros, etc.
Estos depósitos subterráneos no son otra cosa que grandes embalses que generalmente presentan mayor grado de protección frente a fuentes potenciales de contaminación y a variaciones climáticas. Es de resaltar el hecho de que la contaminación de aguas subterráneas es mucho más peligrosa que la contaminación de aguas superficiales, pues generalmente es mucho más difícil de detectar y tratar y se reconoce cuando ya hay daños y victimas.
NCDC scientists and collaborators studied trends for severe convective storms, extreme precipitation, hurricanes and typhoons, and severe snowstorms and ice storms and evaluated the state of knowledge regarding our scientific understanding of the causes of the trends, or lack of trends, they found. The results of their efforts are being published in a paper entitled Monitoring and Understanding Trends in Extreme Storms: State of Knowledge in the Bulletin of the American Meteorological Society.
Highlights of the last week:
• The axis of monsoon trough was south of its normal position during the week.
• The low pressure area which was over northwest Bay of Bengal on 3rd August
moved west-northwestwards across Odisha, Chhattisgarh and Madhya Pradesh.
• All India rainfall during this week was 1% below long period average (LPA) which
has caused 2% improvement in the seasonal rainfall over the country as a whole.
The globally-averaged temperature for July 2012 marked the fourth warmest July since record keeping began in 1880. July 2012 also marks the 36th consecutive July and 329thconsecutive month with a global temperature above the 20th century average.
Most areas of the world experienced much higher-than-average monthly temperatures, including most of the United States and Canada. Meanwhile, Australia, northern and western Europe, eastern Russia, Alaska, and southern South America were notably cooler than average. In the Arctic, sea ice extent averaged 3.1 million square miles, resulting in the second lowest July sea ice extent on record.
The equatorial Pacific Ocean continued to reflect neutral El Niño-Southern Ocean (ENSO) conditions in July. However, according to NOAA's Climate Prediction Center, the El Niño warm ocean phase will likely develop between now and September. In addition to influencing seasonal climate outcomes in the United States, El Niño is often, but not always, associated with global temperatures that are above the average trend. >> More
Climate indicators in the tropical Pacific Ocean remain close to El Niño thresholds. Although El Niño development stalled during the second half of July, over the past fortnight indicators such as the Southern Oscillation Index and trade wind strength have shown renewed trends that are consistent with the early stages of an El Niño event. Likewise, the central Pacific Ocean has continued to warm.
Climate models surveyed by the Bureau of Meteorology continue to show further warming across the tropical Pacific Ocean, with temperatures exceeding El Niño thresholds before the end of September 2012. None of the models surveyed indicate a return to La Niña conditions. >> More

On behalf of the 2 sides, Zheng Guoguang, Administrator of CMA and Baimachilin, Deputy Party Secretary of Tibet Autonomous Region signed the agreement. The 2 sides will strengthen cooperation in guaranteeing the development inputs to meteorological service, intensifying the construction of meteorological projects, improve the meteorological organizations in grass root level and strengthen the meteorological talents construction and the dual management functions. >> More
When typhoon Saola, Damrey and Haikui come one by one rarely in a short time, China Meteorological Administration has strengthened the monitor, early warning and service. Up to 490 million times of warning text messages have been released by the meteorological departments in Shanghai, Jiangsu, Zhejiang, Anhui, Fujian, Jiangxi, Shandong, and Liaoning, which played a very important role in disaster mitigation.
To deal with the typhoons, meteorological departments timely initiated emergency response. For the first time in five years, CMA initiated the level one response on August 7 and sent three task groups to Shandong, Shanghai and Zhejiang. >> More
Si bien los indicadores oceánicos y atmosféricos de julio han convergido en que el fenómeno ENOS se encuentra en la fase de transición de la condición neutra a un evento de El Niño, los impactos climáticos a nivel nacional y regional son más evidentes en indicar que la influencia de El Niño se viene sintiendo desde hace dos meses, pero con mayor intensidad durante julio. La última vez que se presentó este fenómeno en el océano Pacífico fue en abril del 2010. >> Más
Understanding historical hurricane landfalls is important in preparing for current storms
Seeing where hurricanes have hit and how often is one of the best ways to bring home a powerful hurricane preparedness message. A NOAA website, Historical Hurricane Tracks, lets users insert their zip code and see a map that contains more than 150 years of Atlantic hurricane tracking data. The site also contains global hurricane data from as far back as 1842.
“Knowing more about local hurricane history can help communities better understand their vulnerabilities so they can take steps to be more resilient if a future hurricane strikes.” says David Eslinger, Ph.D., an oceanographer with the NOAA Coastal Services Center and one of the site’s developers. >> More
The hugely successful London 2012 Olympics have come to an end but the Met Office is already looking ahead to the Paralympics to once again provide world class forecasts to help everyone make the most of the games.

Four years ago the UK's Met Office forecasters visited the Chinese Meteorological Administration to see how they successfully provided services for the Beijing Olympics. Now, as the Met Office delivers for organisers, athletes and spectators in London, representatives from Brazil's national met service are observing the teams at work to help plan for Rio 2016.
Marcia dos Santos Seabra from Brazil's Instituto Nacional de Meteorologia (INMET) has spent time observing the Met Office forecasting operation on location at Olympic sites and at Exeter Headquarters.
She said: "This has been a great opportunity to learn more about the work the Met Office has been doing ahead of and during the Games. Seeing their cutting edge science, on-site forecasters and clear communications, I have been very impressed with how they have delivered world class forecast services for this fantastic Olympics."John Hirst, Chief Executive of the Met Office, said: "Our job for London 2012 is to help organisers minimise the impact of the weather on the sporting action and make sure everyone, from athletes to the spectators, is prepared for what the weather has in store.
"By offering climate information for all the venues to help advance planning, to utilising the latest technology to deliver the most accurate daily forecasts available, we're helping everyone stay one step ahead of the weather."
WMO Secretary-General Michel Jarraud said: "Weather and climate know no national boundaries, and this is why we need strong international cooperation. Reliable information is critical for many socio-economic activities, including sport. The 2012 Olympics have showcased detailed and accurate weather forecasts for athletes, supporters and organizers. The World Meteorological Organization commends the Met Office for sharing its scientific and technological know-how with the Instituto Nacional de Meteorologia of Brazil for the good of future Olympic Games and indeed future generations."
According to the latest statistics from NOAA’s National Climatic Data Center, the average temperature for the contiguous United States during July was 77.6°F, which is 3.3°F above the 20th-century average. This marks the warmest July and–given that July is the typically the warmest month of the year—the warmest month on record for the nation.
The maps above show average monthly temperature (top) as well as temperature anomaly— where in the United States July 2012 temperatures were different from the 1981–2010 average. Shades of red indicate temperatures up to 8° Fahrenheit warmer than average, and shades of blue indicate temperatures up to 2° Fahrenheit cooler than average—the darker the color, the larger the temperature difference. >> More
Darmstadt/Paris, 7 August 2012 – Today, the Spinning Enhanced Visible and Infrared Imager (SEVIRI) instrument on MSG-3 captured its first image of the Earth. This demonstrates that Europe’s latest geostationary weather satellite, launched on 5 July, is performing well and is on its way to taking over operational service after six months of commissioning.
The European Space Agency (ESA) was responsible for the initial operations after launch (the so-called launch and early orbit phase) of MSG-3 and handed over the satellite to EUMETSAT on 16 July.
The first image is a joint achievement by ESA, EUMETSAT, and the European space industry. For its mandatory programmes, EUMETSAT relies on ESA for the development of new satellites and the procurement of recurrent satellites like MSG-3. This cooperation model has made Europe a world leader in satellite meteorology by making best use of the respective expertise of the two agencies. >> More
ASA's Mars Science Laboratory (MSL) landed successfully on Mars on 6 August at about 08:31 a.m. Finnish time. The laboratory is carrying instruments made by the Finnish Meteorological Institute for measuring pressure and humidity in the Martian atmosphere.
Also known as Curiosity rover, the mobile laboratory reached its destination on Mars on 6 August at about 08:31 a.m. Finnish time. The landing exceeded all expectations, and the first data from Mars indicate that Curiosity is intact and has started to check its technical systems. The rover is the size of a car and weighs about 900 kilograms. It arrived at Mars after a journey of nearly nine months. The rover landed in Gale crater near the equator of Mars. There it is expected to move and explore the area for at least one Mars year, or about 680 Earth days. At the same time, the rover will make observations, for instance, about the geology of the area, the structure of the surface layer, and environmental conditions. If the rover works without problems, its operating lifespan can be extended. >> More
Durante los próximos tres meses las lluvias se mantendrán muy cerca de su promedio histórico a nivel nacional, aunque, como siempre, se registrarán variaciones importantes de región en región, según las estimaciones más recientes de la subgerencia de Pronóstico a Mediano y Largo Plazo del Servicio Meteorológico Nacional (SMN).
En agosto las precipitaciones alcanzarán el 95 por ciento de la media para ese mes --129 milímetros comparados con los 136 mm que habitualmente se registran--, mientras que en septiembre y octubre se ubicarán en 97 y 98 por ciento, respectivamente. >> Más
Tropical situations including oceanic conditions in the recent months:
・ In June 2012, the NINO.3 SST deviation was +0.5°C. SSTs in the equatorial Pacific were above normal. Subsurface temperatures were above normal in almost all regions from the western equatorial Pacific to the eastern part.
・ In the atmosphere, the convective activities were near normal near the dateline in the equatorial Pacific and above normal in the western part.
・ These atmospheric features indicate that ENSO-neutral conditions persisted. >> More
The South African Weather Service is continuing to monitor the weather system that is expected to cause a range of extreme weather conditions over the majority of South Africa as from today, Monday, 6 August 2012 onwards.
The areas most likely to be affected are as follows: Western Cape, Eastern Cape, Northern Cape, KwaZulu-Natal, Free State, Mpumalanga and Gauteng as well as the southern parts of North West province. In other words, the only province not to be directly affected by these extreme winter conditions will be Limpopo province.
The cause of the above-mentioned extreme weather conditions will be the combination of a well-defined cut-off low pressure system (located in the upper regions of the atmosphere), interacting with a cold frontal system. An additional feature associated with this weather pattern, is the presence of a strong surface high (also known as an anticyclone) that will be ridging very strongly overland, immediately following the passage of the cold front. This process of surface ridging is expected to advect (i.e. move horizontally) very cold air from our sub-Antarctic southern ocean areas. Daytime temperatures for South Africa are thus likely to drop significantly over the majority of the interior between today and tomorrow, with many areas likely to experience daytime maximums of only 10˚C (or even less!) by tomorrow. >> More

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 2012 monsoon season. For this, a new Principal Component Regression (PCR) Model based on 5 predictors is useda) The rainfall during August is likely to be normal (96 ± 9% of LPA) as was forecasted in June.
(b) Rainfall over the country as a whole for the second half (August to September) of the 2012 southwest monsoon season is likely to be below normal (<94% of long period average (LPA)).
(c) Quantitatively, rainfall for the country as a whole during the period August to September, 2012 is likely to be 91% of LPA with a model error of ±8%.
(d) Based on the rainfall distribution over the country till date and outlook for the second half of the season, the seasonal rainfall of the entire southwest monsoon season (June to September) is likely to be deficient (< 90% of LPA).
El mes de julio ha sido muy seco, con una precipitación media en torno a los 12 mm, lo que supone un 50% del valor medio normal del mes que es 23 mm. En cuanto a temperaturas, ha sido algo más cálido de lo normal, con una media de 23,9 ºC, que supera en 0,5 ºC a la normal del mes.
Resumen sinóptico del mes
Durante los tres primeros días del mes la circulación atmosférica en altura fue zonal sobre el Atlántico norte y meridiana sobre Europa, con una dorsal rodeando una masa de aire muy cálido sobre el centro del continente. En superficie las altas presiones sobre las Azores y Centroeuropa alcanzaron la Península, mientras las borrascas se desplazaron por latitudes altas y apenas afectaron a zonas distintas de la costa Cantábrica. En el resto de la primera decena la circulación se hizo más meridiana sobre el Atlántico norte, con una vaguada de eje situado ligeramente al oeste de la Península que dio lugar a un flujo del suroeste de cierta intensidad, y a que en superficie se formaran los sistemas de bajas presiones en latitudes más bajas (las correspondientes a Irlanda, Inglaterra y el Mar del Norte) que afectaron al tercio norte peninsular con la entrada de aire fresco y húmedo del Atlántico. >> Más
Flooding in Hanoi after heavy rain. Photo by Tin247
Hanoi aims to put an end to flooding in the city’s centre including the districts of Hoan Kiem, Ba Dinh, Dong Da, Hai Ba Trung and Hoang Mai by 2015.
According to the city's drainage planning to 2030, Hanoi will also complete drainage systems in other residential areas and satellite urban sites in a bid to tackle flooding.
One of the solutions being considered is collecting rainwater.
Currently, the average annual rainfall in Hanoi is 1,676mm, higher than in previous decades due to climate change. In the future, the impacts of climate change will be included in calculating rainfall and drainage system planning. >> More
Under the general prevalence of the subtropical ridge of high pressure, the weather of the first half of the July 2012 was drier and warmer than usual. However, the rainfall deficit was more than compensated by the heavy rain episodes in the latter part of the month respectively brought about by the southwest monsoon and Severe Typhoon Vicente. Overall, the monthly total rainfall was 467.8 millimetres, about 24 percent above the normal. The accumulated rainfall since 1 January was 1395.6 millimetres, about 5 percent below the normal figure of 1473.3 millimetres for the same period. The mean temperature and relative humidity of the whole month are both near-normal.
Under the influence of the subtropical ridge, the weather in Hong Kong was mainly fine and hot apart from a few showers for the first two days of the month. With winds turning light, it was sunny and very hot during the day on 3 and 4 July. The temperature at the Observatory rose to a maximum of 33.8 degrees on 4 July, the highest in the month.>> More

Tropical Pacific remains close to El Niño thresholds
The past fortnight has seen climate indicators ease slightly, with all showing values near the threshold for an El Niño event. While indicators such as the Southern Oscillation Index (SOI), sea surface temperatures and trade winds have eased over the past two weeks, such short-term fluctuations are common and to be expected, and indicators still clearly remain near El Niño thresholds.
Over the last few months, observations have been trending toward El Niño. This is consistent with most model forecasts indicating that the tropical Pacific may approach or exceed El Niño thresholds sometime during the late southern winter or spring 2012. Some models indicate only borderline El Niño conditions may occur, but none suggest a return of La Niña. >> More
Darmstadt/Paris, 16 July 2012 – Today at 14:00 local time, following the successful launch of the satellite on 5 July aboard an Ariane 5 from Europe’s Spaceport in French Guiana, and after 11 days of LEOP (Launch and Early Orbit Phase) by ESA’s Centre, ESOC, EUMETSAT took control of the MSG-3 operations.
During the last 11 days, the satellite was moved into geostationary orbit, the various components which make up the satellite’s platform were activated and their functionality checked. This included a number of critical manoeuvres like the firing of the apogee motors, the change of spacecraft orientation and the unlocking of the SEVIRI scan mirror. >> More

The Hong Kong Observatory has further enhanced its regional weather information service by adding real-time weather photos at Sai Kung to its website starting from today (July 11). Weather photos captured by the two cameras installed at the Sai Kung Marine East Station help to monitor the weather conditions over Sai Kung Hoi, Port Shelter and their surrounding areas.
In recent years, a number of ecological tourist spots have been developed in Sai Kung such as the Hong Kong Global Geopark of China, attracting nature enthusiasts to the region for sightseeing. Many visitors and tourists also go to Sai Kung for leisure and vacation during weekends and public holidays. In addition, the coast of Sai Kung Hoi and Port Shelter is a hotspot for water sports activities where numerous training centres and yacht clubs are located. The newly launched weather photos will provide more weather information for the local residents of Sai Kung as well as people engaged in outdoor activities there.

New NOAA-led report examines climate conditions experienced around the worldThe lead character of the 2011 climate story was a double dip La Niña, which chilled the Pacific at the start and end of the year. Many of the 2011 seasonal climate patterns around the world were consistent with common side effects of La Niña.
Worldwide, 2011 was the coolest year on record since 2008, yet temperatures remained above the 30 year average, according to the 2011 State of the Climate report released online today by NOAA. The peer-reviewed report, issued in coordination with the American Meteorological Society (AMS), was compiled by 378 scientists from 48 countries around the world. It provides a detailed update on global climate indicators, notable weather events and other data collected by environmental monitoring stations and instruments on land, sea, ice and sky. >> More

The average temperature for the contiguous U.S. during June was 71.2°F, 2.0°F above the 20th century average, ranking as the 14th warmest June on record. Scorching temperatures during the second half of the month broke or tied over 170 all-time temperature records in cities across America. June temperatures also contributed to a record-warm first half of the year and the warmest 12-month period the nation has experienced since recordkeeping began in 1895.
Warmer-than-average temperatures anchored across the Intermountain West and much of the Great Plains during June. Colorado had its warmest June on record, with a statewide temperature 6.4°F above average. Seven additional states in the region had a top ten warm June. However, cooler-than-average temperatures were present for the Pacific Northwest, where Washington had its seventh coolest June on record. Cool conditions were also present for the Southeast, despite record warm temperatures towards the end of the month. >> More
MSG-3 was successfully launched from Kourou, Europe’s Spaceport in French Guiana, on an Ariane-5 launcher to replace the ageing Meteosat-8 and secure continuity of the operational services from the geostationary orbit. Alain Ratier, EUMETSAT’s Director-General, said, “Together with Meteosat-9, MSG-3, the future Meteosat-10, will form the two-satellite Meteosat Second Generation system that supports weather forecasters in their time-critical nowcasting tasks. This involves detecting and monitoring rapidly developing high impact phenomena like thunderstorms or fog and issuing related warnings”. >> More
ENSO Alert System Status: El Niño Watch
During June 2012, ENSO-neutral continued as reflected in both the oceanic and atmospheric
anomalies. However, positive equatorial Pacific sea surface temperature (SST) anomalies have grown, exceeding +0.5°C across the eastern Pacific Ocean by the end of June (Fig. 1). SST anomalies increase moving from the westernmost Niño 4 region to the Niño 1+2 region adjacent to South America, which remained near +1.5°C during the month (Fig. 2). The oceanic heat content anomalies (average temperature in the upper 300m of the ocean) increased during June (Fig. 3), as above-average sub-surface temperatures became more entrenched in the equatorial Pacific (Fig. 4). This warming was consistent with a weakening of the low-level trade winds across the east-central equatorial Pacific, along with a weakening of the persistent pattern of enhanced convection near Papua New Guinea (Fig. 5). The observations are consistent with ENSO-neutral, but reflect a likely progression towards El Niño. >> More

Resumen sinóptico del mes
En la primera mitad del mes, en el Atlántico norte y Europa, la situación atmosférica en altura se caracterizó por un vórtice circumpolar que formó vaguadas en el Atlántico por encima del paralelo 50º N, mientras mantenía un flujo zonal en latitudes inferiores, en torno al paralelo 40º N. Al comienzo del mes, en superficie, se dieron en nuestra área geográfica situaciones de pantano barométrico, con la Península situada entre dos sistemas de altas, uno en las Azores y otro sobre el este de Europa, y dos sistemas de bajas: el correspondiente a las borrascas situadas en el Atlántico norte y noroeste de Europa (paralelo 60º N) y el de bajas térmicas en el norte de África. A partir de la mitad de la quincena se asentó el anticiclón de las Azores, y con él el régimen los alisios en las islas Canarias, y el paso de las borrascas por latitudes algo más bajas que las correspondientes a Islandia. Estos sistemas de bajas presiones llegaron a afectar al norte de la Península, tanto en la mitad como al final de la segunda quincena, con la entrada de aire procedente del Atlántico, fresco y húmedo. >> Más
June 2012 was drier than usual, especially in the first half of the month. This was mainly attributed to the predominance of the ridge of high pressure and lacking of active trough of low pressure over the south China coastal areas during the early part of the month. The total rainfall of the month was 261.5 millimetres, about 43 percent below the normal figure of 456.1 millimetres. The accumulated rainfall since 1 January was 927.8 millimetres, a deficit of 15 percent comparing to the normal figure of 1096.8 millimetres for the same period. The month was also slightly warmer than usual with the mean temperature of 28.1 degrees, 0.2 degrees above the normal figures of 27.9 degrees.
Under the influence of a ridge of high pressure, the weather in Hong Kong was generally fine apart from a few showers for the first four days in the month. It remained fine and hot with moderate easterly winds from 5 to 7 June. As winds turned southerly, it became very hot apart from a few showers on 8 June. >> More
En analysant des observations effectuées depuis le sol au-dessus de Niamey (Niger) et des données spatiales, des chercheurs du Centre national de recherches météorologiques
(CNRM - GAME, Météo-France / CNRS) et de l'Université de Reading ont élaboré une base de données inédite sur la nébulosité en Afrique de l’Ouest. Elle recense les types de nuages observés dans la région, leur fréquence d'occurence et leur altitude pendant toute une année. Ces données serviront notamment à évaluer la capacité des modèles climatiques à reproduire les propriétés nuageuses dans cette région, pour laquelle les modèles peinent à s'accorder sur des scénarios de température ou de précipitations pour les prochaines décennies. Publiés en mars 2012 dans la revue Journal of Applied Meteorology and Climatology, ces résultats sont présentés cette semaine dans le cadre de la 4ème conférence internationale du programme AMMA (Analyses Multidisciplinaires de la Mousson Africaine). >> suite

The mean temperature for June was below average in Finland. The anomaly was
over a degree Celsius in the western parts and less than one degree in the
eastern parts of the country. This was the coolest June in Finland since
The highest temperature of 27.0 °C was recorded at Kouvola on the 16th. The lowest temperature of -2.3 °C was recorded at Alajärvi on June 1st. The majority of the country faced above average precipitation and some locations received double the average amount. Joensuu was the wettest location with 142 mm of precipitation. Parts of Eastern Lapland received some snow in late June which is not exceptional, but also not an every-year-event.
There were only a few active thunderstorm days. The recorded lightning strikes amounted to less than fifth of the average amount. >> More
Increasing risk of El Niño in 2012Climate indicators continue to show a shift towards El Niño, in line with most model predictions. Eastern and central tropical Pacific Ocean temperatures have continued to warm over the past fortnight, while trade winds have remained weaker than normal. Likewise, the Southern Oscillation Index (SOI) has become more strongly negative over the past month. Tropical Pacific Ocean observations are consistent with previous and current climate model forecasts, which have indicated that the tropical Pacific may approach or exceed El Niño thresholds sometime between mid-winter and spring 2012. During El Niño events, large parts of eastern Australia are typically drier than normal during winter and spring, while southern Australian daytime temperatures tend to be warmer. However, El Niño does not guarantee widespread dry conditions. The Indian Ocean Dipole (IOD) is currently neutral. About half of the outlooks from POAMA, the Bureau’s climate model, indicate the possibility of a weak positive IOD event developing during winter or spring. Should a positive IOD event eventuate with an El Niño event, this increases the likelihood of dry conditions over southern Australia. >> More

The dry season has come a little late this year as some areas will still have a chance for rain showers, a senior official says.
The Meteorology, Climatology, and Geophysics Agency (BMKG)’s deputy director general for climatology, Widada Sulistya, said Monday that Indonesian should have already entered the dry season in May, although in fact, some areas were still experiencing the rainy season.
“The drought will not be too dry this year. In some areas there will still be some rain during the dry season, although the rain showers will not occur as what happened in 2010. Currently, we occasionally have rain, but it is not as wet as in 2010. During that year , rain fell throughout the year,” he said.
Citing the BMKG data, he said that about 65 percent of a total of 342 season zones (ZOM) in Indonesia had entered the dry season. They include most areas in Java, the southern parts of Sumatra, such as Lampung, East Nusa Tenggara (NTT) and West Nusa Tenggara (NTB). >> More

Although climate indicators remain at neutral (neither El Niño nor La Niña) levels, the tropical Pacific continues to slowly warm. Climate models surveyed by the Bureau suggest this warming trend will continue over the coming months, with the majority of the models indicating the tropical Pacific will approach or possibly exceed El Niño thresholds by the end of winter. No climate models favour a return to La Niña during the remainder of 2012.
Large parts of eastern Australia are usually, but not always, drier than normal in winter and spring during El Niño events. >> More

The scientific evidence for ongoing anthropogenic climate change is overwhelming, and impacts of changes over recent decades are already apparent in the Nordic region as well as in most other regions of the world. Irrespective of how climate change proceeds, it is wise to develop societal resilience against extreme weather events, such as record heat waves, heavy precipitation and high winds. Such extreme events can not only harm the directly impacted area, but their effects reverberate through trade relations to many countries around the globe. Therefore, adaptation is important both in the public and private sector. >> More

Tropical Pacific climate indicators remain at neutral values for this time of the year. This includes the Southern Oscillation Index (SOI), trade winds, cloudiness, and sea surface temperatures. Ocean temperatures below the surface are currently warmer than average in the central and western Pacific on a monthly scale, with the eastern subsurface Pacific closer to normal, but slowly warming.
Climate models surveyed by the Bureau of Meteorology show that the tropical Pacific Ocean is likely to warm further over the coming months. All seven models surveyed indicate conditions are likely to approach, or possibly exceed, El Niño thresholds during the late winter to early spring period. Large parts of eastern Australia are typically drier and warmer than normal in winter/spring as El Niño events develop. No climate models favour a return to La Niña.
While the Indian Ocean Dipole (IOD) is currently considered neutral, the IOD index has been positive for the past three weeks. About half of the current POAMA outlooks show sustained positive levels in 2012.
La température moyenne du printemps sur la France est supérieure de près de 0,8 °C à la normale* de saison. Elle est supérieure à la normale sur l’est de la France et plus proche de la normale sur la moitié ouest.
Sur l’ensemble de la France, la quantité d’eau recueillie est légèrement supérieure (environ 10%) à la normale*. Après un mois de mars chaud et sec, les mois d’avril et mai ont été bien arrosés avec des températures plus conformes aux normales de saison. Les précipitations sont assez contrastées. Excédentaires en Bourgogne, sur le sud des Alpes, l’ouest de la Corse ainsi que sur la moitié ouest du pays, elles sont en revanche déficitaires sur le nord-est, la Picardie, au nord du Massif central, sur les côtes du Languedoc-Roussillon et sur le piémont pyrénéen. >> suite
Le printemps 2012 a été marqué par un fort excédent thermique compris entre 2 et 2.5 degrés par rapport à la norme climatologique 1961-1990. Les précipitations ont été souvent inférieures à la normale, sauf au Sud des Alpes. Le printemps 2012 a également été plus ensoleillé que d'habitude. >> suite

The Met Office and Lloyd's, the world's specialist insurance market, have teamed up to promote the latest scientific research on North Atlantic hurricanes.
Landfalling hurricanes in the US are the costliest of all natural hazards, with the total bill for Hurricanes Katrina, Wilma and Rita in 2005 reaching an estimated $90bn.
Hurricanes and Long-term Climate Variability, a report from Lloyd's and the Met Office, examines the latest research papers from a number of leading organisations. >> More
When the first hurricane emerges from the Atlantic Ocean or Gulf of Mexico this season, NOAA will use a new statistical model to help predict the start of the “eyewall replacement cycle,” a key indicator that a storm’s strength and size is about to change dramatically. This new tool adds to a suite of forecast products NOAA uses to warn coastal communities of imminent threats.
An eyewall is an organized band of clouds that immediately surround the center, or eye, of a hurricane. The most intense winds and rainfall occur near the eyewall. Within a hurricane, eyewall replacement cycles occur when a second concentric eyewall forms around the original and eventually overtakes it. This phenomenon especially happens in strong, long-lived hurricanes. >> More

Climate is the natural characteristic of a country. Life and natural processes depend on it and there is almost no human activity which does not depend on weather and climate. Therefore, awareness of particular climate characteristics is especially important when planning development activities in many social and economic areas. Following the recommendation of the World Meteorological Organisation, each member state meteorological service is expected to develop a Climate Atlas.>> More
Met Office research suggests industrial air pollution is largely responsible for changes in the temperature of the Atlantic Ocean which are linked to drought, flooding and hurricane activity.
Published in the journal Nature, the study is the first to clearly link aerosol 'dirty pollution' and, to a lesser extent, volcanic eruptions to observed 20th century temperature variations in the Atlantic Ocean.
These shifts in ocean temperature, known as the Atlantic Multidecadal Oscillation or AMO, are believed to affect rainfall patterns in Africa, South America and India, as well as hurricane activity in the North Atlantic - in extreme cases leading to humanitarian disasters. >> More

The 2011–12 La Niña event has ended, with key indicators returning to neutral (neither El Niño nor La Niña) levels. Climate models surveyed by the Bureau of Meteorology suggest that neutral conditions will persist until at least early winter.
Key Pacific Ocean indicators are now at neutral levels, with values similar to those last seen in August 2011. Likewise, atmospheric indicators such as cloudiness, trade winds and the Southern Oscillation Index (SOI) have also returned to near-normal values for this time of year. Despite the 2011–12 La Niña not commencing until far later than normal (spring), the decline has been fairly typical of past events, with a peak in January and a return to neutral conditions during autumn.
The demise of the La Niña does not mean the risk of wet conditions (or tropical cyclones) over Australia has ended. While sea surface temperatures around the continent remain warmer than normal and the tropical wet season is active, there remains a risk of above average rainfall over Australia.
The Indian Ocean Dipole (IOD) has limited influence on Australian rainfall from December through to April. Neutral IOD conditions are forecast for the southern hemisphere winter.

Genève, le 23 mars 2012 – La 9e édition du Forum International de la Météorologie et du
Climat, qui se tenait pour la 1ère fois à Genève, au siège de l’OMM (Organisation
Météorologique Mondiale), a fermé ses portes sur un bilan très satisfaisant.
«Le temps, le climat et l'eau: les moteurs de notre avenir». C'est sous ce thème que la journée internationale de la Météorologie du 23 mars célébrera l'entrée en vigueur de la Convention de l'Organisation météorologique mondiale (OMM). MétéoSuisse, l'Office fédéral de météorologie et de climatologie, est l'un de des 189 membres qui contribuent par ses prestations à ce que nous puissions continuer à profiter du temps, du climat et de l'eau à l'avenir.
L'année 2011 a été globalement l'année la plus chaude jamais enregistrée; depuis le début des mesures, jamais la glace de l'Arctique n'a été aussi fine, ni la concentration des gaz à effet de serre aussi haute. Les conséquences du changement climatique, qu'il s'agisse de tempêtes, sécheresses, crues ou autres catastrophes naturelles et météorologiques, se manifestent sous de multiples aspects. L'agriculture, la protection de la population, l'énergie, les transports et le tourisme - dans tous ces domaines, le changement climatique nous met face à de grands défis. Pour maîtriser les risques induits par les changements climatiques à moyen et à long terme, il est indispensable et d'une grande importance économique de pouvoir disposer d'informations météorologiques et climatiques fiables. Voilà ce que veut souligner l'OMM et ses membres, dont MétéoSuisse, lors de la journée mondiale de Météorologie de cette année, en traitant le thème «Le temps, le climat et l'eau: les moteurs de notre avenir».
The federal advisor on climate affairs, Dr Qamar uz Zaman Chaudhry, has said that the National Climate Change Policy, recently approved by the federal cabinet, has been formulated with the aim of incorporating the factor of climate change in various socially vulnerable aspects of the economy for ensuring climate resilient development in the country.
Talking to The News on Saturday, Dr Chaudhry who is also Vice-President of World Meteorological Organization, Asia Region, highlighted the significance of National Climate Change Policy by saying that Pakistan was among 10 most climate change-vulnerable countries in the world. “The last two years’ devastating floods in the country proved this aspect clearly. The approval of this policy is well-timed and a significant development for the country,” said Dr Chaudhry.
“The main objectives of the policy are to pursue sustained economic growth by appropriately addressing the challenges of climate change and integrate this policy with other inter-related national policies. Also the policy is further aimed at ensuring water, food and energy security in the country,” he said.
This March 23 is the 52nd World Meteorological Day whose theme is "Powering Our Future with Weather, Climate and Water". This theme demonstrates that people have understood the important role of weather, climate and water in human being's future. In our sustainable development practice, all the countries should join together to help more and more sensitive weather, climate and water resources to drive future development and find out solutions to solve the problems in the present human being's development.
As an important part of natural environment and resources, weather and climate are important for people's production and life. Weather has close relation with our life and has always caught our attention. Colorful material and intellectual civilizations come from changes of climate and resource environment. Water is source of life and one of the most important resources for human being's sustainable survival and healthy life. We take powers for weather, climate and water to power our growth as well as experience difficulties brought by them: about 90% natural disasters are linked with weather, climate and water.
This State of the Climate is the second paper produced by CSIRO and the Australian Bureau of Meteorology. It provides a summary of observations of Australia’s climate and analysis of the factors that influence it. It notes that the long-term warming trend has not changed, with each decade having been warmer than the previous decade since the 1950s. The warming trends observed around Australia are consistent with global-scale warming that has been measured during recent decades, despite 2010 and 2011 being the coolest years recorded in Australia since 2001. Global-average surface temperatures were the warmest on record in 2010 (slightly higher than 2005 and 1998). 2011 was the world’s 11th warmest year and the warmest year on record during a La Niña event. The world’s 13th warmest years on record have all occurred in the past 15 years.
Aunque las lluvias registradas durante la primera mitad de febrero de este año representaron un cierto alivio, la situación de la sequía en México sigue siendo grave, especialmente en algunos estados del norte de la República Mexicana.

En moyenne nationale, février 2012 a été un des 10 mois de février les plus froids depuis le début des mesures il y a quelque 150 ans. La vague de froid qui a frappé la Suisse au cours de la première quinzaine a été la plus intense depuis 27 ans. Malgré le froid, février a été extrêmement sec et ensoleillé.
El mes de febrero ha sido extremadamente frío, con una temperatura media de 6,0 ºC, que queda 2,5 ºC por debajo de la media. Es el mes de febrero con un valor medio de las temperaturas mínimas diarias más bajo desde el año 1956. También ha sido muy seco, con una precipitación media que no llega al 30% de la normal. Se trata del mes de febrero más seco desde el año 2000.
Febrero ha sido extremadamente frío en España, con una temperatura media mensual de 6,0 ºC, valor que queda 2,5 ºC por debajo del valor medio normal del mes (Periodo de referencia: 1971-2000). Se trata del cuarto mes de febrero de temperatura media mensual más baja desde el año 1961, después de los correspondientes a los años 1963, 1965 y 2005. Debido a las acusadas oscilaciones diurnas de temperatura registradas bajo condiciones de escasez de nubosidad, la anomalía térmica negativa ha sido especialmente acusada en el caso de las temperaturas nocturnas, habiendo sido el mes de febrero con un valor medio de las temperaturas mínimas diarias más bajo desde el año 1956.

L’hiver 2011-2012 s’est montré particulièrement contrasté en France métropolitaine, alternant douceur et froid exceptionnel, pluies abondantes et déficit de précipitations.
Si la température moyennée sur la France et sur l’ensemble de l’hiver a été conforme à la normale, elle masque d’importantes variations. Les températures ont été très douces en décembre et janvier, avant de chuter brusquement fin janvier. Dès lors, une vague de froid remarquable a touché l’ensemble du pays jusque vers la mi-février, la fin de l’hiver connaissant ensuite des températures plus proches des normales*.
Après un mois de décembre abondamment arrosé à l’exception notable des régions méditerranéennes, les précipitations de janvier n’ont concerné que le Nord-Est et le nord des Alpes, précédant un mois de février remarquablement sec. Sur l’ensemble de la saison, le bilan pluviométrique est extrêmement déficitaire sur les régions méditerranéennes avec des cumuls de pluie souvent inférieurs à 20 % de la normale : cet hiver s’y classe parmi les plus secs depuis 1959. Sur le reste de la France, le bilan est contrasté : nettement déficitaires de la Bretagne au Sud-Ouest, les pluies ont été plus proches des normales ailleurs, voire parfois excédentaires sur le Nord et le Nord-Est de la France.
L’ensoleillement a été généreux cet hiver, notamment grâce à un mois de février très ensoleillé. Des Pays de la Loire aux frontières du Nord et du Nord-Est ainsi que sur les régions méditerranéennes, les durées d’ensoleillement ont été 20 % à 40 % supérieures à la moyenne**. Partout ailleurs, l’ensoleillement a été plus proche de la moyenne.
Working in cooperation with the Sudan Meteorological Authority (SMA), the Finnish Meteorological Institute launched a project funded by the Finnish Ministry for Foreign Affairs.
The aim of the cooperation is to develop the SMA’s organisation and human resources so that the SMA can produce and convey more advanced weather and climate services for various sectors of society. The project also supports the ongoing large investment project for modernising the observation network in Sudan. As part of the project, the Finnish Meteorological Institute’s experts train their Sudanese colleagues, for instance, how to operate and service modern weather observation instruments and how to utilise the data obtained for supplying society with increasingly better products and services.
The project also includes a separate segment of assistance to South Sudan, which is helped to develop an independent weather service
In recent years, China's meteorological disaster change has new conditions and characteristics: on one hand, under the backdrop of global warming, some extreme weather and climate events hit frequently which cause more and more dangerous meteorological disasters. On the other hand, with the socio-economic development, the influences of meteorological disasters show new conditions. When different industries improve the cooperation, the chain effect becomes prominent in the influence and intensity of meteorological disaster. Urbanization brings highly concentration of population and property, which causes severe vulnerability. To meet the needs of people's subsistence and development, resource and environment are destroyed which deepens the meteorological disaster. Therefore, China will face new challenges in terms of disaster prevention and reduction and responding to climate change.
On 5 February 2012, at 20.25 Moscow time, an event, the anitcipation of which had kept the international scientific community and many members of the domestic and foreign mass media in suspense, took place at Russia's inland research station Vostok in Antarctica. Specialists with the glaciological and drilling unit of the 57th Russian Antarctic expedition penetrated the relict waters of sub-glacial Lake Vostok at a depth of 3769.30 meters through a deep ice borehole. The event was confirmed by the digital data of the drilling parameters, which were recorded with a video camera, and by the rising level of the [drilling] fluid in the borehole, as well as by the extracted water sample and core of lake ice, which is being stored at the Vostok ice-core depository. >> More
The National Meteorological Service of Mexico celebrates its 135th anniversary this year, with a special ceremony 6 March attended by WMO Secretary-General Michel Jarraud. A special commemmorative book has been published to mark the anniversary.
La communauté climatique française, réunissant principalement Météo-France, le CNRS, le CEA, l’UMPC et l’UVSQ (notamment à travers le CNRM, le CERFACS* et l’IPSL**) vient de terminer un important exercice de simulations du climat passé et futur à l’échelle globale (CMIP-5). Mis à disposition de la communauté internationale, ce travail sera utilisé par le Groupe d’experts intergouvernemental sur l’évolution du climat (GIEC) pour établir son 5e rapport, dont le premier volet sera publié à la mi-septembre 2013.
La mission du GIEC est de recenser et de résumer toute l’information scientifique sur le changement climatique, ses impacts et les solutions pour l’atténuer ou s’y adapter. Tous les cinq ou six ans, ses rapports font un nouvel état des connaissances accumulées, en s’appuyant notamment sur les résultats de simulations du climat effectuées par une large communauté internationale. Pour cette édition, l’exercice de simulations a rassemblé une vingtaine de centres climatiques de par le monde. Il présente en outre un certain nombre d’innovations par rapport aux éditions précédentes, notamment la prise en compte de scénarios de gaz à effet de serre incluant des politiques climatiques de réduction des émissions et l’utilisation de modèles plus complexes et plus précis. Et pour la première fois, des prévisions climatiques pour la période 2010-2040 ont aussi été effectuées.
Changements de la température à la surface de la Terre pour la période 2071-2100 par rapport à celle de la période 1971-2000 calculés par les modèles du CNRM-CERFACS et de l'IPSL pour le scénario moyen RCP4.5
Mexico has been experiencing one of its driest years in history. 2011 was the 13th most arid year since records were started in 1941. The amount of rainfall for the country as a whole was 697.1 mm, an anomaly of 11 per cent compared to the climatology of 778.8 mm. The main problem was the irregular distribution of the precipitation, as only three states had 15 per cent more than their average yearly rainfall, while 15 states recorded a deficit greater than 15 per cent. Some states suffered their driest year in history.
The National Meteorological Service (SMN) of Mexico prepared a PDF document with the 2011 Climatological Summary, which explains the rainfall and temperature situation month by month and offers graphics and statistics.

Today, the Honourable Peter Kent, Minister of the Environment, announced that the Harper Government is investing $78.7 million over the next five years to strengthen weather monitoring infrastructure, ensuring Canadians continued access to world-class weather, water and climate monitoring data.
“Canadians understand the impact that weather, particularly severe weather, has on all of us,” said Minister Kent. “This investment in Environment Canada’s weather monitoring infrastructure will result in improved weather forecasts and warnings to better protect Canadians.”
The infrastructure upgrades will strengthen the Department’s core weather monitoring networks including the weather radar network, which is the backbone of Canada’s severe weather warnings service. The upgrades will also modernize the monitoring infrastructure and help Environment Canada’s weather service keep pace with the rapid evolution of new science and technologies.
According to NOAA scientists, 2011 was a record-breaking year for climate extremes, as much of the United States faced historic levels of heat, precipitation, flooding and severe weather, while La Niña events at both ends of the year impacted weather patterns at home and around the world.
NOAA’s annual analysis of U.S. and global conditions, conducted by scientists at NOAA’s National Climatic Data Center, reports that the average temperature for the contiguous U.S. was 53.8 degrees F, 1.0 degree F above the 20th century average, making it the 23rd warmest year on record. Precipitation across the nation averaged near normal, masking record-breaking extremes in both drought and precipitation.
On a global scale, La Niña events helped keep the average global temperature below recent trends. As a result, 2011 tied with 1997 for the 11th warmest year on record. It was the second coolest year of the 21st century to date, and tied with the second warmest year of the 20th century.
At 11:30 a.m. on January 19 (Beijing Time), the National Satellite Meteorological Center of China Meteorological Administration (CMA) obtained the first image of the FY-2F meteorological satellite.
"In comparison with the FY-2E satellite, the quality of the image of FY-2F has greatly enhanced," said academician Xu Jianmin. The space environment observing device carried in the satellite opened on January 18 and observed two solar flares.
The FY-2F satellite was launched in Xichang Satellite Launch Center on January 13. On January 18, it was positioned at 112 E above equator. Based on the second batch of FY-2 satellite and the users’ need, the research and development unit has made technological improvement in the new satellite, such as extending service life from 3 to 4 years and doubling intensive observation life. The satellite is possessed with high time and resolution scanning capability for specific region, equipped with space environment observing device, and improved the visible light and infra-red radiation of cloud image which will enhance the observation efficiency, operating stability, observing quality and the accuracy of quantitative products.

Il constitue une source d’informations inestimable sur l’histoire du climat.
On January 6, CMA issued "2011 China’s climate report" in Beijing. This report pointed out that in 2011 China’s climate was generally warm and dry; China’s average temperature was moderately high and 2011 was continuously the 15th warm year; China’s average precipitation was the minimum of nearly 60 years; rain belt of flood season moved towards north; regional and periodical meteorological disaster occurred frequently. According to preliminary statistics, in 2011, the direct economic loss caused by main meteorological disasters was 303 billion yuan, which was higher than the average number from 1990 to 2010. 1049 people were lost or missed, fewer than normal years.
According to data, the average temperature of China in 2011 was 9.3℃, 0.5℃ higher than the normal years. Days of high temperature in southern China were more than normal level.
Under the background of higher average temperature, the precipitation of 2011 was less. China’s average annual precipitation was 556.8mm, 9% less than the normal years as well as the minimum since 1951. From winter to next summer, the precipitation was continuously less. The situation was "flood in the north and drought in the south".
At the end of December 2011, Lithuania signed the accession agreement to become a full Member State of EUMETSAT by 1 January 2014, subject to ratification by the Lithuanian parliament.
At the same time, Lithuania signed the extension of its Cooperating State agreement with EUMETSAT by a further two years to cover the period 2012-2013. The two agreements were signed by Mr. Gediminas Kazlauskas, the Lithuanian Minister of the Environment, and Alain Ratier, Director-General of EUMETSAT.
Lithuania will become a full Member State of EUMETSAT by 2014 after having been a Cooperating State since 2005. Ratier welcomed the Lithuanian accession: “The signature of the accession agreement is the result of active cooperation between Lithuania and EUMETSAT. It clearly shows that Lithuania is aware of the value of our satellites for the monitoring of weather, climate and the environment, and will soon be ready to fully participate in strategic decisions on our future programmes, such as the EUMETSAT Polar System Second Generation.”

La Comisión Nacional del Agua (Conagua) recomendó a las autoridades y a la población prepararse para posibles descensos bruscos de temperatura, extremar la eficiencia en el uso del agua —especialmente en las actividades agropecuarias— e incrementar las medidas de prevención de incendios forestales, debido a que se prevé que continúe el invierno seco, heladas de mayor intensidad y una prolongación de la sequía hasta el verano próximo, informó José Luis Luege Tamargo, Director General de la dependencia.
Para prevenir daños a la salud de la población como consecuencia del frío, hizo énfasis en la importancia de atender diariamente los pronósticos y avisos del Servicio Meteorológico Nacional (SMN) —dependiente de la Conagua—, solicitar a las autoridades estatales y municipales de Protección Civil informes sobre la ubicación de refugios temporales, no dormir a la intemperie y cuidar de manera especial a las personas más vulnerables.
Enero es el tercer mes del período poco lluvioso en Cuba, el que se extiende hasta el mes de abril. Se produce en este mes una mayor afectación de los frentes fríos y de las masas de aire continentales en relación con los meses anteriores, lo que influye en el establecimiento de condiciones invernales con frecuencia.
En enero las precipitaciones dependen fundamentalmente de los sistemas frontales que afectan al país. Es a su vez uno de los meses menos lluviosos del año. Para el actual enero se prevén totales de precipitación cercanos o inferiores a lo normal en las regiones occidental y central, así como cercanas a lo normal en la región oriental del país

This year, flash flood affected some areas in upper Thailand since mid-May. In June, heavy rainfall occurred in many locations throughout the month caused by the influence of the active southwest monsoon and monsoon trough which lies across the upper Thailand.
The rainfall amount of Thailand since 1 January to 31 October was 1822.4 millimeters, about 28 percent above normal and the October rainfall was 201.8 millimeters, 10 percent above normal. Seasonal rainfall from May to October in 2011 was above normal of 20 – 60% for most Meteorological Station in northern part and of 10 - 40% with below normal in some areas in central part.
L’année 2011 restera dans les annales comme ayant battu le record de la température moyenne annuelle à Bruxelles-Uccle. C’est en effet l’année la plus chaude depuis 1833, lorsque l’on a commencé des observations météorologiques régulières à Bruxelles-Uccle. La température moyenne annuelle a atteint 11,6°C, soit 1,1°C au-dessus de la valeur moyenne sur la période 1981-2010 (c’est-à-dire la valeur « normale »). Cette valeur est aussi 0,1°C au-dessus du précédent record qui datait de 2007 et 0,2°C au-dessus de la valeur de 2006.

30 December 2011 - Provisional figures from the Met Office reveal temperatures this December have been close to average, but 2011 overall is the second warmest year on record for the UK.
The mean temperature so far this December has been 4.7 °C, 0.5 °C above the 1971-2000 average. This is a big swing from 2010, when temperatures were 5 °C below average to notch up the coldest December on record.
Weather in 2011: one of the five warmest years in Germany since 1881 Offenbach, 29 December 2011 – In 2011, the average temperature in Germany was 9.6 degrees Celsius (°C), which puts the ending year among the five warmest years since 1881. At 7.8°C, the previous year w as significantly cooler. The record temperature is still 9.9°C, recorded in 2000 . When it comes to sunshine, 2011 even takes a podium position: in Germany only 2003 and 1959 saw more sunshine, as the initial analysis by the Deutscher Wetterdienst (DWD) of data from its around 2,000 weather stations shows.
The Bureau of Meteorology has released its Annual Climate Statement today (4 Jan), highlighting a year likely to go down as the third wettest on record, with widespread and severe flooding across northern and eastern Australia.
Last year's weather was dominated by two La Niña events. The first, one of the strongest in recorded history, began in 2010 and continued into the autumn of 2011. The second, weaker event, formed toward the end of winter.
The Spanish term La Niña translates as the ‘girl-child’. The meteorological opposite of El Niño, La Niña is associated with cooling in the central and eastern Pacific Ocean which often plays out in increased rainfall, particularly in the eastern states
