JMA’s New Nowcasting information debuts in record-rainy August 2014 (Japan Meteorological Agency)
Posted 2 December 2014


Numerous landslides and flash floods were caused by short-term heavy rain in the Western Pacific region of Japan during record-rainy August 2014. In the same month, the Japan Meteorological Agency (JMA) launched new-generation nowcasting products to support individual self-protection actions against sudden heavy rain.

HRPNs are characterized by the application of radars with different
features, the X-band (10 GHz) multi-parameter RAdar Information
Network (XRAIN) operated by Japan’s Ministry of Land, Infrastructure, Transport and Tourism (MLIT), and JMA’s C-band (5 GHz) radars. Various types of JMA monitoring, such as Automated Meteorological Data Acquisition System (AMeDAS), upper-air radiosonde and wind profiler observation, also assist in determining the nationwide distribution of rainfall. >> More

Un mois d'octobre exceptionnellement chaud (Météo France)
Posted 25 November 2014


La prédominance de flux de sud au cours de ce mois d'octobre a favorisé des températures élevées sur la France. Ces conditions ont aussi occasionné deux épisodes de précipitations intenses sur les régions méditerranéennes en début de mois.

Les températures ont été très chaudes durant la quasi-totalité du mois sur l'ensemble du pays, avec des maximales généralement supérieures à 20 °C sur une large moitié sud. Les maximales ont été 2 à 4 °C au-dessus des normales* sur la quasi-totalité du pays. Moyennée sur la France et sur le mois, la température a été supérieure de 2.4 °C à la normale. Ce mois  a été le 4e mois d'octobre le plus chaud depuis 1900, derrière 2001, 2006 et 1995. >> suite

 

The weather in Germany in October 2014 (Deutscher Wetterdienst)
Posted 25 November 2014

Unusually warm and exceptionally varied

Offenbach, 30 October 2014 – October 2014 will be remembered as the third warmest October since records began in 1881. Taking the months of January to October as a whole, the temperature is around 2.1 degrees higher than average and is therefore a new record. In most of Germany, October started with high pressure and an Indian summer. This was then followed nearly everywhere by a warm south-westerly to southerly airflow with precipitation in the north and west but also fairly long, dry phases in the south and east. Fog often formed in river valleys at night. This changed at the start of the last ten days of the month when the remnants of the hurricane ‘Gonzalo’ passed over Germany. Accompanied by storm gusts, some of which were violent, the low pressure system caused a sharp fall in the temperature, continuous rainfall in the south and the first falls of snow in the mountains. By the end of the month, calm and mild high pressure weather conditions again dominated, with sun but also fog and low stratus cloud cover. This is what the initial analysis by the Deutscher Wetterdienst (DWD) of data from its around 2,000 weather stations shows. >> More

Volcanic ash - getting a clearer picture (MetOffice)
Posted 25 November 2014

ZEUS, a device developed by the Met Office and the Natural Environment Research Council (NERC) to improve our understanding of atmospheric volcanic ash distribution, has been fitted to a British Airways 747 aircraft.

Following the Icelandic volcanic eruption in 2010, which caused widespread flight disruption, scientists at the Met Office and NERC developed a prototype device capable of detecting small amounts of ash in the atmosphere. In time, this research could aid ash forecasting and also help airlines more accurately plan their flight and engineering operations.

The ZEUS prototype uses measurements of static electricity to detect small levels of atmospheric volcanic ash and can distinguish between the levels of electrostatic charge on the aircraft when flying in normal conditions and when volcanic ash is present. It has been fitted on a British Airways 747 and data has already been successfully downloaded from its first flight to Johannesburg and it will continue to fly on long-haul routes around the world for a year, collecting data for analysis. >> More

Samoa Tropical Cyclone Outlook 2014-2015 season (Samoa Meteorology Division)
Posted 25 November 2014

Samoa Meteorology Division, Ministry of Natural Resources and Environment through the
Samoa Climate Early Warning System (CLEWS) predicts elevated cyclone activity for
Samoa this season. Two or more named cyclones are predicted to interact with the Samoa
islands during the season, from 1st November 2014 to 30th April 2015. The risk of tropical
cyclones this season is no different to the cyclone season 2012-2013 (most recent); where
Samoa interacted with Tropical Cyclone Evan and Tropical Cyclone Garry.


This outlook is based on statistical analysis of historical TC events that have occurred in
similar ENSO conditions. Eight analogue seasons were used in this analysis. Based on
historical tropical cyclone data, for El Niño Southern Oscillation conditions such as this
particular season, one or more storms expected to reach category 3 status with mean wind
speeds of at least 64 knots or 118 km/h (wind speeds similar to Tropical Evan), at least one or more storms to reach category 4 status with mean wind speeds of at least 86 knots or 159 km/h (wind speeds similar to Tropical Val). While Category 5 strength TCs (winds greater than 106 knots or 196 km/h and similar to Tropical Ofa) have not been prominent for ENSO neutral seasons like the current one, this type of event is still possible. Therefore, all
communities should remain alert and prepared for severe events. >> More

Weather balloons at Valentia Observatory (The Irish Meteorological Service)
Posted 25 November 2014


Valentia Observatory is part of Met Éireann's synoptic station network. At the Observatory we carry out a number of meteorological measurements, both at surface level and in the upper atmosphere, as well as a wide range of other scientific activities including environmental monitoring and geophysical observations. The Observatory is called Valentia because it was originally located on Valentia Island but it has been in its current location, beside the town of Caherciveen, since 1892. As part of our meteorological observations, we launch weather balloons to obtain a profile of the weather conditions at various heights above the Earth’s surface.

Upper-air ascents are carried out at Valentia Observatory to measure meteorological parameters throughout the atmosphere. Measurements of pressure, temperature, humidity, wind speed and wind direction are made at heights of up to 35km. The equipment we use is a radiosonde, which is connected to a helium-filled balloon that is released from a launcher at the station. As the balloon rises through the atmosphere, continuous measurements are taken and transmitted back to the ground station by the radiosonde. It also keeps track of the balloon’s position and location using GPS. Two ascents are carried out per day at Valentia – at 0000Z and 1200Z. These are synchronised with launches from other upper-air stations around the globe. >> More

The Philae lander successfully touched down on the surface of the 67P/Churyumov-Gerasimenko comet.

An instrument developed by the Finnish Meteorological Institute (FMI) for measuring the comet's water content will be the first to touch down on the comet surface. According to the latest information, the Permittivity Probe (PP) instrument and Mass Memory developed by FMI for Philae have been functioning according to expectations.
The Mass Memory processes all data collected and sends it to the orbiter, which then transmits the data to Earth.

"The successful touchdown is a huge success story, because no one has ever landed on a comet before. Because the Finnish Meteorological Institute plays a major role in the mission, this is also a major demonstration of Finnish know-how," explains Minna Palmroth, FMI Research Professor. >> More

Repeat of last year's extremely cold, snowy winter east of Rockies unlikely

Below average temperatures are favored in parts of the south-central and southeastern United States, while above-average temperatures are most likely in the western U.S., Alaska, Hawaii and New England, according to the U.S. Winter Outlook, issued today by NOAA’s Climate Prediction Center.

While drought may improve in some portions of the U.S. this winter, California's record-setting drought will likely persist or intensify in large parts of the state. Nearly 60 percent of California is suffering from exceptional drought – the worst category – with 2013 being the driest year on record. Also, 2012 and 2013 rank in the top 10 of California’s warmest years on record, and 2014 is shaping up to be California’s warmest year on record. Winter is the wet season in California, so mountainous snowfall will prove crucial for drought recovery. Drought is expected to improve in California’s southern and northwestern regions, but improvement is not expected until December or January. >> More

Heavy rainfall and dry spells are common in the countries surrounding the Niger River in West Africa. Researchers from SMHI in Sweden and the AGRHYMET regional centre in West Africa have jointly developed a tool which can provide a better quantification of the hydrological fluxes in the Niger River basin.

Water is an important natural resource in the Niger River basin, and is a prerequisite for e.g. the smallholder agriculture in the area.

– The populations are heavily dependent on the river and the cooperation between countries is crucial. With support of a hydrological model we can predict the hydrological situation. For example, already in the beginning of the rainfall season we can forecast the seasonal outcome, says Dr. Abdou Ali, senior hydrologist from the regional organisation AGRHYMET in Niger. >> More

Bureau releases Tropical Cyclone Outlook for 2014–15 (Bureau of Meteorology - Australian Government )
Posted 30 October 2014

The Bureau of Meteorology has released its annual Tropical Cyclone Outlook today, with average to below-average tropical cyclone activity likely for the 2014–15 season.

Bureau Climate Prediction Manager, Dr Andrew Watkins, said in an average year around 11 tropical cyclones form in the oceans surrounding northern Australia during the November to April cyclone season.

"History shows that about half of all cyclones that form over Australian waters have some impact on coastal regions, which means that even during an average or below-average season we would expect to see a number of impacts for communities in northern Australia."

Dr Watkins said while most ocean and atmospheric indicators have fallen short of El Niño thresholds so far, the El Niño-like ocean pattern occurring in the tropical Pacific Ocean has had an influence on this year's Tropical Cyclone Outlook, and there still remains a 50 per cent chance of El Niño developing during the cyclone season. >> More

New report finds human-caused climate change increased severity of 2013 heat waves in Asia, Europe and Australia (NOAA)
Posted 10 October 2014

Credit: Bulletin of the American Meteorological Society

A report released today investigates the causes of a wide variety of extreme weather and climate events from around the world in 2013. Published by the Bulletin of the American Meteorological Society, "Explaining Extreme Events of 2013 from a Climate Perspective" addresses the causes of 16 individual extreme events that occurred on four continents in 2013. NOAA scientists served as three of the four lead editors on the report.

Of the five heat waves studied in the report, human-caused climate change-primarily through the burning of fossil fuels-was found to have clearly increased the severity and likelihood of those events. On the other hand, for other events examined like droughts, heavy rain events, and storms, fingerprinting the influence of human activity was more challenging. The influence of human-caused climate change on these kinds of events was sometimes evident, but often less clear, suggesting natural factors played a far more dominant role. >> More

 

NOAA’s weather forecasts go hyper local with next-generation weather model
Posted 10 October 2014

Credit: NOAA

New model will help forecasters predict a storm’s path, timing and intensity better than ever.

Today, meteorologists at NOAA’s National Weather Service are using a new model that will help improve forecasts and warnings for severe weather events. Thanks to the High-Resolution Rapid Refresh (HRRR) model, forecasters will be able to pinpoint neighborhoods under threat of tornadoes and hail, heavy precipitation that could lead to flash flooding or heavy snowfall and warn residents hours before a storm hits. It will also help forecasters provide more information to air traffic managers and pilots about hazards such as air turbulence and thunderstorms.

Developed over the last five years by researchers at NOAA’s Earth System Research Laboratory, the HRRR is a NOAA research to operations success story. It provides forecasters more detailed, short-term information about a quickly developing small-scale storm by combining higher detail, more frequent radar input and an advanced representation of clouds and winds. The HRRR model forecasts are run in high resolution every hour using the most recent observations with forecasts extending out 15 hours, allowing forecasters to better monitor rapidly developing and evolving localized storms. >> More

Air pollution increases river-flows (UK MetOffice)
Posted 10 October 2014

 A study published in Nature Geoscience today shows that air pollution has had a significant impact on the amount of water flowing through many rivers in the northern hemisphere.

The paper shows how such pollution, known as aerosols, can have an impact on the natural environment and highlights the importance of considering these factors in assessments of future climate change. The research resulted from a collaboration between scientists at the Met Office, Centre for Ecology and Hydrology, University of Reading, Laboratoire de Météorologie Dynamique in France, and the University of Exeter.Nicola Gedney, from the Met Office and lead author of the paper, said: "We detect the impact of solar dimming on enhanced river flows over regions in the heavily industrialised northern extra-tropics. We estimate that, in the most polluted central Europe river basin, this effect led to an increase in river flow of up to 25% when the aerosol levels were at their peak, around 1980. With water shortages likely to be one of the biggest impacts of climate change in the future, these findings are important in making projections for the future." >> More

Neutral, but El Niño WATCH remains (Australian Government - Bureau of Meteorology)
Posted 10 October 2014

Tropical Pacific Ocean ENSO indicators remain within the neutral range, having failed to maintain sustained values typical of El Niño. However, given the persistent warmth in the tropical Pacific Ocean, models continue to suggest an El Niño remains possible during the last quarter of 2014. Atmospheric indicators of El Niño have remained neutral over recent months. Tropical cloud patterns and trade winds have only had brief periods with El Niño-like values since May. Despite a recent drop into El Niño territory, the Southern Oscillation Index (SOI) has returned to neutral values over the past fortnight. Model outlooks and current observations mean the Bureau’s El Niño WATCH remains in place, indicating double the normal chance (50%) of an El Niño over the coming months. While still falling short of El Niño thresholds, the tropical Pacific Ocean remains warmer than average. When combined with recent cool water to the north of Australia, conditions favour below-average rainfall over much of Australia for the remainder of 2014. The Indian Ocean Dipole (IOD) has returned to neutral recently after being consistently negative since June. Climate models surveyed by the Bureau indicate neutral conditions are very likely to remain during the last quarter of 2014. >> More

Chemicals released into the air by oil and gas exploration, extraction and related activities can spark reactions that lead to high levels of ozone in wintertime, high enough to exceed federal health standards, according to new NOAA-led research, published today in Nature.

The study comes at a time when new technologies are helping to accelerate oil and gas development in Utah’s Uintah Basin, elsewhere in the United States and in many other countries, and its findings may help air quality managers determine how to best minimize the impact of ozone pollution. When ozone levels spike, Environmental Protection Agency (EPA) experts recommend that people, especially those in sensitive groups — children, the elderly, and anyone with pre-existing respiratory conditions — limit time outdoors.>> More

 

Climate outlook overview (Australian Government - Bureau of Meteorology)
Posted 29 September 2014

A drier than normal October to December is more likely for broad areas of eastern Australia and parts of northwestern WA. Conversely a wetter than normal outlook is more likely for most of Tasmania. The October outlook suggests drier conditions are likely over much of central and eastern Australia. There are also strong odds for drier conditions over the northern coastal areas of WA. The October to December temperature outlooks are for warmer than normal days over most of Australia particularly in the far southeast, and warmer than normal nights with the exception of the northern tropical regions. Climate influences include warmer than normal temperatures in the tropical Pacific Ocean and a neutral Indian Ocean Dipole. >> More

Met Office launches renewables service in Germany (UK Met Office)
Posted 29 September 2014

The Met Office has announced the launch of its renewable energy services in Germany. Increasing uptake of its renewables offerings in targeted European countries is a key growth objective for the Met Office, which continues to increase its market share in the UK. The German market is set to see a dramatic shift towards offshore activity. According to the Global Wind Energy Council, by 2020 installed onshore wind capacity is predicted to increase by 40% to reach 45,000MW, whilst offshore capacity will increase by 1,460% to 6,000MW. The larger 6-8MW turbine capacities and higher wind speeds are a driving force in Germany's offshore wind farm construction and operations activity. According to a recent  PricewaterhouseCoopers study, turnover across the whole offshore value chain, from planning and building to operations and maintenance, is expected to grow to €22.4m in 2021 from €5.9m in 2010, an increase of 280% in turnover in 10 years. >> More

 

Research on intense precipitation could increase preparedness upon local flooding (SMHI)
Posted 29 September 2014

In recent times, abundant rainfall over southwestern Sweden has caused high water levels and flooding. An ongoing research project is developing flow forecasts which are better at capturing the effects of sudden downpours. It allows for better preparedness upon local, extreme water flows in the future. Intense precipitation, in the form of, for example, heavy rainfall, may cause very high water and flooding at a local level. Especially vulnerable are cities and areas that are bare and steep. Today, there is no system to warn of floods caused by extreme rainfall.- We need better descriptions of how powerful bursts rapidly affect the flow process. Especially because of the fact that extreme rainfall may increase in the future due to a warmer climate, says Jonas Olsson, researcher in hydrology at SMHI.A tool with more detailed information may provide a better basis for assessing the risk of extreme water flows.- We work with using radar observations in combination with station data and we evaluate and test how to use more detailed precipitation forecasts, says Jonas Olsson. We also adjust the receiving system called S-HYPE, which is used to make hydrological predictions, so that it is possible to forecast with short time intervals. >> More

Bulletin climatologique août 2014 (MeteoSuisse)
Posted 18 September 2014

Août 2014 a été régionalement au Tessin le mois d’août le plus froid
de ces 30 dernières années. Pour les autres régions de Suisse, ce mois
d’août a été entre le deuxième et le quatrième le plus froid depuis 30
ans. L’ensoleillement a été particulièrement faible sur l’ensemble de
la Suisse. Au Tessin, le manque de soleil a à nouveau occasionné des
valeurs record. Le mois d’août le plus froid au Tessin depuis 30 ans
environ. Après un mois de juillet frais, pluvieux et peu ensoleillé,
août s’est également présenté comme peu estival. Les températures
moyennes journalières sont restées inférieures à la normale pendant
presque tout le mois. Au cours des périodes les plus fraîches, du 13
au 17 et du 20 au 25 août, les températures étaient entre 3 et 6
degrés inférieures à la norme 1981-2010, voire entre 5 et 7 degrés
inférieures en montagne. Seules 6 journées ont connu des températures journalières supérieures à la normale. Du 8 au 10 août, les températures journalières ont été entre 1 et 3 degrés au-dessus de la normale grâce à un courant du sud-ouest qui a dirigé de l’air chaud,
humide et instable, propice aux développements orageux. Dans les
régions à foehn, l’excédent thermique était parfois supérieure à 5
degrés. En revanche, au Sud des Alpes, les températures journalières
sont généralement restées inférieures à la normale au cours de ces 3
journées. Du 28 au 30 août, grâce à un bon ensoleillement, les
températures journalières sont parvenues à être entre 1 et 1.7 degré
au-dessus de la norme des deux côtés des Alpes.>> suite

Point sur la situation hydrologique (MeteoFrance)
Posted 18 September 2014

Carte bsh juin2014

Le mois d'août 2014 a été particulièrement frais et humide, avec un déficit d'ensoleillement sur de nombreuses régions. Le cumul des précipitations et la fraîcheur des températures ont contribué à une forte humidification des sols, sur la moitié nord du pays. Sur la période du 1er septembre 2013 - début de l'année hydrologique - à la fin août 2014, la quantité d'eau disponible pour l'écoulement et la recharge des nappes phréatiques est excédentaire de plus de 50% sur une large partie de la France, à l'exception du littoral du Roussillon à l'Hérault, qui lui présente un déficit de 50 à 75%. L'indice d'humidité des sols* dépasse quant à lui la normale sur les deux tiers nord de la France. Sur l'est du pays, après un début d'année particulièrement sec, les pluies et les températures fraîches de juillet et août ont largement contribué à humidifier les sols. Sur le tiers sud, cet indice est proche de la normale, voire légèrement déficitaire. Les sols sont particulièrement secs en Corse avec un déficit qui dépasse 80% sur le nord-ouest de l'île et localement sur le littoral est de la Corse-du-Sud. >> suite

This year has seen an exceptionally long heatwave, with temperatures of more than 25°C being recorded by at least one weather station every day since 6th June. The adverse health effects of the hot weather are not yet known, but those most at risk are the chronically ill and
elderly people living either at home or in some form of residential care unit. Yesterday, 12th August, was still officially a hot day, but it's unlikely we'll experience the same degree of heat today, says the on duty weather forecaster at the Finnish Meteorological Institute.

Should the magic number of 25.1°C not be reached today, then the duration of the heatwave will come to a total of 38 days. Finland has only once before experienced a similar heatwave since records began in 1961. The heatwave in the summer of 1973 also lasted for 38 days. This year, the ground temperature reached at least 30°C on a total of 22 days. This is the most frequent since 1961. With regard to individual weather stations, the longest periods of continuous hot weather this summer were recorded at both Utti in the Kuovola region and Lepaa in the Hattula region, where 26 consecutive days of hot temperatures were recorded between 17th July and 11th August.>> More

El Niño still a possibility for 2014
Posted 19 August 2014

The Pacific Ocean has shown some renewed signs of El Niño development. Some warming has occurred in the central and eastern equatorial Pacific Ocean in the recent fortnight, due to a weakening of the trade winds. If the trade winds remain weak, more warming towards El Niño thresholds is possible.

The Bureau’s ENSO Tracker remains at WATCH status. This means the chance of an El Niño developing in 2014 is at least 50%, which is double the normal likelihood of an event. Five of the eight climate models surveyed by the Bureau suggest El Niño is likely for spring. However, if El Niño were to occur, it is unlikely to be a strong event. El Niño is often associated with below-average rainfall over southern and eastern inland areas of Australia and above-average daytime temperatures over southern Australia. Similar impacts regularly occur prior to the event becoming fully established. >> More


Effects of aerosols on autumn precipitation over mid-eastern China - CMA
Posted 19 August 2014

Long-term observational data indicated a decreasing trend for the amount of autumn precipitation (i.e. 54.3 mm per decade) over Mid-Eastern China, especially after the 1980s (~ 5.6% per decade). To examine the cause of the decreasing trend, the mechanisms associated with the change of autumn precipitation were investigated from the perspective of water vapor transportation, atmospheric stability and cloud microphysics.

Results show that the decrease of convective available potential energy (i.e. 12.81 J kg-1/ decade) and change of cloud microphysics, which were closely related to the increase of aerosol loading during the past twenty years, were the two primary factors responsible for the decrease of autumn precipitation.  >> More

Three-Month Climate Characteristic Expectations of Thailand - Thailand
Posted 19 August 2014

Upper Thailand (Northern, Northeastern, Central and Eastern parts of Thailand): During August until September: The southwest monsoon still prevails over Thailand with being active from time to time; additionally, a monsoon trough places over the upper Thailand in some periods. This characteristic will bring about abundant rain over the upper Thailand; scattered to almost widespread rainfall with heavy to very heavy rains in some areas.

Thus, flash floods, flooding situations and over-flows occur in some areas. Winds and waves in the Gulf of Thailand around the eastern coast will be rough with 2 – 4 meters high in some periods. Afterwards, high pressure air masses from China prevailing over Northern and Northeastern parts periodically cause to reduce the amount of rainfall and rainfall distribution around upper Thailand, then starting to have cold air in the morning, especially the upper of Northern and Northeastern Thailand. >> More

Southern California residents lose millions of dollars each year avoiding littered, local beaches in favor of choosing cleaner beaches that are farther away and may cost more to reach, according to a new NOAA-funded Marine Debris Program economics study.

Reducing marine debris even by 25 percent at beaches in and near California’s Orange County could save residents roughly $32 million during three months in the summer by not having to travel longer distances to other beaches.

The study, led by Cambridge, Massachusetts-based Industrial Economics Inc., known as IEc, is the first of its kind to look at how marine debris influences decisions to go to the beach and what it may cost. >> More

AEMET

La Agencia Estatal de Meteorología (AEMET) dependiente del Ministerio de Agricultura, Alimentación y Medio Ambiente, ha contribuido, junto a la Organización Meteorológica Mundial (OMM) y a los países del Mediterráneo, a la puesta en marcha del foro MedCOF (Mediterranean Climate Outlook Forum) cuya última acción ha sido la generación de una predicción probabilística consensuada de temperatura y precipitación de la estación estival (junio, julio y agosto) para toda la región del Mediterráneo.

MedCOF es uno de los Foros Regionales sobre la Evolución Probable del Clima. Estos foros tienen como objetivo inicial reunir periódicamente a expertos de una región climatológicamente homogénea –en este caso, la región mediterránea- para generar una predicción consensuada generalmente de alcance estacional.

Esta última reunión ha tenido como novedad que se que ha realizado online durante dos semanas de mayo utilizando la página ( http://medcof.aemet.es) y el foro diseñado por AEMET para este propósito. El producto final ha sido una predicción estacional consensuada entre los 33 países que integran el MedCOF y para toda la región con la ventaja de haberse realizado de un modo más sostenible. >> Mas

Preliminary Outlook for Monsoon 2014 - Pakistan
Posted 23 June 2014

Pakistan Summer Monsoon Season spans over July to September. As a routine practice, Pakistan Meteorological Department (PMD) issues the Monsoon Outlook around mid June incorporating the dynamics of local, regional and global meteorological parameters up to the end of May each year. However, South Asian Climate Outlook Forum (SASCOF-5) designated by World Meteorological Organization (WMO) has already issued Consensus Statement. Outlook made by this forum and preliminary outlook of PMD are presented below:

South Asian Climate Outlook Forum (SASCOF-5) - The outlook suggests that below normal to normal rainfall is most likely over South Asia as a whole. Below normal rainfall is likely over broad areas of western, Central and Southern parts of the South Asia and some areas in the northeastern-most parts of the region. Normal rainfall is likely over broad areas of northwestern and eastern parts and some island areas in the southern most part of the region. It is noteworthy that no part of the South Asia is likely to receive above normal rainfall.

Preliminary Monsoon Outlook by PMD - The emerging climatic features linked to El-Nino development have fairly large potential to suppress Pakistan Summer Monsoon 2014. According to the preliminary estimates of PMD, the amount of rainfall from July to September may be moderately below normal in Sindh, Balochistan and Southern Punjab while nearly normal rainfall is expected in North Punjab, KP, GB and Kashmir. >> More

NOAA’s Climate Prediction Center announced today that a near-normal or above-normal hurricane season is likely for the Eastern Pacific this year. The outlook calls for a 50 percent chance of an above-normal season, a 40 percent chance of a near-normal season, and a 10 percent chance of a below normal season. Seasonal hurricane forecasters are calling for a 70 percent chance of 14 to 20 named storms, which includes 7 to 11 hurricanes, of which 3 to 6 are expected to become major hurricanes (Category 3, 4 or 5 on the Saffir-Simpson Hurricane Wind Scale).

An average Eastern Pacific hurricane season produces 15 named storms, with eight becoming hurricanes and four becoming major hurricanes. The Eastern Pacific hurricane season runs from May 15 through Nov. 30, with peak activity from July through September.>> More

NOAA predicts near-normal or below-normal 2014 Atlantic hurricane season
Posted 28 May 2014

NOAA HUrricane 2014 Atlantic hurricane outlook (Credit:NOAA)

El Niño expected to develop and suppress the number and intensity of tropical cyclones. In its 2014 Atlantic hurricane season outlook issued today, NOAA’s Climate Prediction Center is forecasting a near-normal or below-normal season.

The main driver of this year’s outlook is the anticipated development of El Niño this summer. El Niño causes stronger wind shear, which reduces the number and intensity of tropical storms and hurricanes. El Niño can also strengthen the trade winds and increase the atmospheric stability across the tropical Atlantic, making it more difficult for cloud systems coming off of Africa to intensify into tropical storms.

The outlook calls for a 50 percent chance of a below-normal season, a 40 percent chance of a near-normal season, and only a 10 percent chance of an above-normal season. For the six-month hurricane season, which begins June 1, NOAA predicts a 70 percent likelihood of 8 to 13 named storms (winds of 39 mph or higher), of which 3 to 6 could become hurricanes (winds of 74 mph or higher), including 1 to 2 major hurricanes (Category 3, 4 or 5; winds of 111 mph or higher). >> More

Typhoon Francisco and Super Typhoon Lekima on October 23, 2013 as they tracked northwestward toward China and Japan. (Credit: Tim Olander and Rick Kohrs, SSEC/CIMSS/UW-Madison, based on Japan Meteorological Agency data.)

Researchers find that the average latitude where tropical cyclones achieve maximum intensity has been shifting poleward since 1980.

Over the past 30 years, the location where tropical cyclones reach maximum intensity has been shifting toward the poles in both the northern and southern hemispheres at a rate of about 35 miles, or one-half a degree of latitude, per decade according to a new study, The Poleward Migration of the Location of Tropical Cyclone Maximum Intensity, published tomorrow in Nature. As tropical cyclones move into higher latitudes, some regions closer to the equator may experience reduced risk, while coastal populations and infrastructure poleward of the tropics may experience increased risk. With their devastating winds and flooding, tropical cyclones can especially endanger coastal cities not adequately prepared for them.

Additionally, regions in the tropics that depend on cyclones' rainfall to help replenish water resources may be at risk for lower water availability as the storms migrate away from them. >> More

Warm Season Outlook for Summer 2014 in Japan - Japan
Posted 16 May 2014

In summer 2014, mean temperatures are expected to be either near or below normal (both with 40% probability) in northern Japan and either near or above normal (both with 40% probability) in western Japan and Okinawa/Amami. Total summer precipitation amounts are expected to be either near or above normal (both with 40% probability) in northern Japan, and either near or below normal (both with 40% probability) in western Japan. 1. Outlook summary JMA issued its outlook for the coming summer over Japan in February and updated it in March and April. In summer (June – August) 2014, mean temperatures are expected to be either near or below normal (both with 40% probability) in northern Japan, and either near or above normal (both with 40% probability) in western Japan and Okinawa/Amami. Summer total precipitation amounts are expected to be either near or above normal (both with 40% probability) in northern Japan, and either near or below normal (both with 40% probability) in western Japan (Figure 8). Rainy season (Baiu) precipitation amounts are unlikely to exhibit particular characteristics in any region. 2. Outlook background JMA’s coupled global circulation model predicts that the NINO.3 SST will transition from near to above normal in summer. In conclusion, although the continuation of ENSO-neutral conditions may be possible considering the large uncertainties of the model’s prediction, it is more likely that El Niño conditions will develop. >> More

Climate Characteristic Expectations of Thailand during the Rainy Season 2014 - Thailand
Posted 16 May 2014

The rainy season of Thailand this year is expected to begin lately than usual, about at the 3rd – 4th week of May. The summarized rain is expected to be less than normal and less than that of last year’s, especially at the beginning of the rainy season. However, during the end of the rainy season, many areas of the upper Thailand will have the amount of rainfall being near the normal. General Weather Characteristics: About at the end of May until June: Southwest monsoon will be prevalent covering the Andaman Sea and Thailand by being rather active in some periods. Additionally, a monsoon trough will place over the upper Thailand from time to time. These will cause the upper Thailand to have abundant rainfall with heavy rains in some areas. About at the end of June until middle July: The monsoon trough placing over the upper Thailand will move upward to place over southern China causing many areas of Thailand to have not much rainfall during this beginning of the rainy season. Thus, shortage of water for agriculture happens in many areas, especially often at drought areas outside irrigation zones. >> More

Retreating sea ice will lead to more Arctic precipitation - Netherlands
Posted 16 May 2014

Schematic representation of sea ice retreat, enhanced surface evaporation from the open ocean and the increase in Arctic precipitation (KNMI) Schematic representation of sea ice retreat, enhanced surface evaporation from the open ocean and the increase in Arctic precipitation (KNMI)

Retreating sea ice resulting from global warming will lead to a strong increase in Arctic precipitation. Climate models project that this increase will be as much as 60 percent.

According to Richard Bintanja and Frank Selten, both climate scientists at the KNMI, most of the increase can be attributed to local evaporation. Model results show that sea ice retreat will lead to a strong increase in surface evaporation, possibly even a threefold increase. Until now scientists thought that moisture inflow from lower latitudes was the main cause of the precipitation increase, but this new finding demonstrates that the increase in evaporation associated with sea ice retreat is the most important factor. >> More

Probabilistic MME forecast from WMOLC LRF: 2m Temperaturea

The Qatar Meteorological Department is introducing monthly and seasonal (3-month) climate outlooks for Qatar and adjoining regions, beginning April 2014. Monthly and seasonal climate forecasts are generated world wide with an underlying assumption that sea surface temperatures in global oceans, snow-cover, soil-moisture of the land surface and other such slowly varying boundary conditions determine the ensuing global and regional climate anomalies.

Leading climate centers around the world use fully coupled ocean-atmosphere general circulation models for generating seasonal climate forecasts wherein both sea surface temperatures and associated atmospheric circulation co-evolve. Climate forecasts are generally in the form of anomalies from a long-term climatology as simulated in the models. Individualn climate centers produce monthly/seasonal forecasts based on a large suite of simulations (generally initiated every month and extending 6 months in to the future) with different initial conditions using their global climate model and then develop an ensemble forecast product employing advanced statistical technique. >> More

Third National Climate Assessment for the United States

The National Climate Assessment provides information about climate change impacts on all major regions of the United States and critical sectors of society

Today, the Obama Administration unveiled the Third U.S. National Climate Assessment. This report confirms that climate change is affecting Americans in every region of the U.S. and key sectors of the national economy.

Certain types of extreme weather events with links to climate change have become more frequent and/or intense, including prolonged periods of heat, heavy downpours, and in some regions, floods and droughts. In addition, warming is causing sea level to rise and glaciers and Arctic sea ice to melt, and oceans are becoming more acidic as they absorb carbon dioxide. These and other aspects of climate change are disrupting people's lives and damaging some sectors of our economy. >> More

El Niño likely in 2014: Australia
Posted 5 May 2014

The likelihood of El Niño remains high, with all climate models surveyed by the Bureau now indicating El Niño is likely to occur in 2014. Six of the seven models suggest El Niño thresholds may be exceeded as early as July.

The Pacific Ocean has been warming along the equator over recent weeks, with continued warming in the central Pacific likely in coming months. Another burst of westerly winds is presently occurring in the western Pacific, and is likely to cause further warming of the sub-surface.

El Niño has an impact across much of the world, including below average rainfall in the western Pacific and Indonesian regions, and increased rainfall in the central and eastern Pacific. For Australia, El Niño is usually associated with below average rainfall, with about two thirds of El Niño events since 1900 resulting in major drought over large areas of Australia.>> More

 

India Issues Monsoon Outlook
Posted 5 May 2014

Operational models are critically reviewed regularly and further improved through in- house research activities. Operational forecasts for the southwest monsoon season (June – September) rainfall are issued in two stages. The first stage forecast is issued in April and the second stage forecast is issued in June.

(a) Quantitatively, the monsoon seasonal rainfall is likely to be 95% of the Long Period Average (LPA) with a model error of ± 5%. The LPA of the season rainfall over the country as a whole for the period 1951-2000 is 89 cm.

(b) The 5 category probability forecasts for the Seasonal (June to September) rainfall over the country as a whole is given below:
ESSO-IMD will issue the update forecasts in June, 2014 as a part of the second stage forecast. Along with the update forecast, separate forecasts for the monthly (July and August) rainfall over the country as a whole and seasonal (June-September) rainfall over the four geographical regions of India will also be issued. >> More

 

Hong Kong extends weather forecast from 7 days to 9 days
Posted 5 May 2014

In recent days, Hong Kong Observatory has extended weather forecast from 7 days to 9 days. According to Cheng Cho-ming, Assistant Director of Hong Kong Observatory, the accuracy of weather forecast would reduce with the extension of the forecasting days. Currently, the mean accuracy rate of their 1 to 3-day forecast is 90%, 4 to 7-day forecast, 85% and the new 8 to 9-day forecast, 80%.

Cheng said that although the accuracy rate of 8 to 9-day forecast was lower than the forecast before 7 days, it marked that Hong Kong Observatory has developed and promoted the weather forecasting quality with the extension of forecast days. The goal was to meet the needs of local residents. They could get weather forecast earlier, make preparations for activities and take measures for preventing disastrous weather.

According to Mr. Chun Chi-ming, Director of Hong Kong Observatory, local people could check weather forecast of the coming 9 days from the website of the observatory.>> More

According to NOAA’s Spring Outlook released today, rivers in half of the continental United States are at minor or moderate risk of exceeding flood levels this spring with the highest threat in the southern Great Lakes region due to above-average snowpack and a deep layer of frozen ground. Additionally, drought is expected to continue in California and the Southwest. The continuation of winter weather, above-average snowpack, frozen ground and thick ice coverage on streams and rivers will delay spring flooding into April in the upper Midwest eastward to New England. The intensity of the flooding will depend on the rate of snow and ice melt, and future rainfall. >> More

SEASONAL CLIMATE OUTLOOK January – June 2014 - Philippines
Posted 28 March 2014

SEASONAL CLIMATE OUTLOOK
SEASONAL CLIMATE OUTLOOK

El Niño Southern Oscillation (ENSO)-neutral conditions persisted during the remaining months of 2013 up to December, as reflected by near-average sea surface temperature (SST) across the central and east-central equatorial Pacific (CEEP). Most model forecasts continue to indicate ENSO-neutral condition into early 2014, with an increasing chance towards a warming trend during Northern Hemisphere summer of 2014.

January – March 2014:
The period is the peak of the Northeast (NE) monsoon season, locally known as “Amihan”. Tropical cyclone activity is however at its minimum. Weather systems that may affect the country are the NE monsoon, tail-end of a cold front, trough of low pressure areas (LPAs), Intertropical Convergence Zone (ITCZ), easterlies and one (1) to two (2) tropical cyclones that are likely to develop/enter the Philippine Area of Responsibility (PAR). Cold surges are expected during the period.

For January-February-March season, rainfall conditions will likely be near to above normal in most parts of the country while patches of below normal rainfall maybe observed over Northern and Central Luzon during January. Sulu and Tawi - tawi are expected to receive below normal rainfall during February and similarly over Cordillera Autonomous Region (CAR), Nueva Ecija, Eastern Samar and Northern Palawan during March. Gradual weakening of the NE monsoon may begin during the early part of March.

April to June 2014: The period covers the gradual shift of the season from NE monsoon to Southwest (SW) monsoon. The weather systems that may influence the country are the ridge of high pressure area (HPA), ITCZ, LPAs and three (3) to six (6) tropical cyclones. During the period, the mean track of tropical cyclones is located from southern Luzon to central Visayas areas, extending towards the West Philippine Sea. During April, generally way below to below normal rainfall are likely to occur in most parts of the country, except in some areas in Western Mindanao and portions of CARAGA Region which are expected to receive near to above normal rainfall. Likewise, near to above normal rainfall maybe experienced during May and June. This condition may favor the normal onset of the rainy season (latter part of May or early part of June) in areas under climate Type. >> More

Increased chance of El Niño in 2014 - Australia
Posted 28 March 2014

Monthly sea surface temperatures
Monthly sea surface temperatures

While the tropical Pacific Ocean remains El Niño–Southern Oscillation (ENSO) neutral, the chance of an El Niño occurring in 2014 has increased. The latest climate model survey by the Bureau shows that the tropical Pacific is likely to warm in the coming months, with most models showing sea surface temperatures reaching El Niño thresholds during the southern hemisphere winter.

Observations indicate that the tropical Pacific Ocean is currently warming. Following two strong westerly wind bursts since the start of the year, waters below the surface of the tropical Pacific have warmed significantly over the past two months. This has led to some warming at the surface, with further warming expected in the coming weeks. The Southern Oscillation Index (SOI) has dropped to –13—the lowest 30-day value since March 2010—but would need to remain firmly negative for several weeks to indicate the atmosphere and ocean are reinforcing each other. El Niño is often, but not always, associated with below normal rainfall across large parts of southern and inland eastern Australia during the second half of the year. Daytime temperatures also tend to be above normal over southern Australia. >> More

Warming tropical Pacific increases chance of El Niño from winter - Australia
Posted 13 March 2014

Finland Press release archive: 2014Photo: Eija Vallinheimo
Monthly sea surface temperatures

The El Niño–Southern Oscillation (ENSO) remains neutral – neither El Niño nor La Niña. However, international climate models surveyed by the Bureau indicate that warming of the tropical Pacific is likely in the coming months, with most models showing temperatures approaching or exceeding El Niño thresholds during the austral winter.

Recent observations indicate that warming of the tropical Pacific is occurring. The tropical Pacific Ocean sub-surface has warmed substantially over the past few weeks, which is likely to result in a warming of the sea surface in the coming months. A recent burst of westerly winds over the far western Pacific is the strongest seen since at least 2009 – the last time an El Niño developed.

El Niño is often, but not always, associated with below-average rainfall during the second half of the year across large parts of southern and inland eastern Australia. Daytime temperatures also tend to be above average over southern Australia. >> More

 

State of the Climate 2014: A clear picture of Australia's climate - Australia
Posted 13 March 2014

A definitive report on observed changes in long term trends in Australia’s climate has been released today by CSIRO and the Bureau of Meteorology.

Bureau Chief Executive Dr Rob Vertessy said temperatures across Australia were, on average, almost 1°C warmer than they were a century ago, with most of the warming having occurred since 1950.

“Australia’s mean temperature has warmed by 0.9°C since 1910,” Dr Vertessy said.

“Seven of the ten warmest years on record in Australia have occurred since 1998. When we compare the past 15 years to the period 1951 to1980, we find that the frequency of very warm months has increased five-fold and the frequency of very cool months has decreased by around a third.

“The duration, frequency and intensity of heatwaves have increased across large parts of Australia since 1950. >> More

Posted 13 March 2014

North India consisting of seven subdivisions (East U.P., West U.P. Uttaranchal, Haryana, Punjab, Himachal Pradesh, Jammu & Kashmir) receives about 17% of its annual rainfall during the winter season (January to March). The Jammu & Kashmir in particular receives about 30% of its annual rainfall during this period. The winter rainfall is very crucial for Rabi crops over the region. It is also crucial for the water management of the region. In view of these reasons, India Meteorological Department (IMD) has been issuing long range forecast outlook for the winter rainfall over north India. IMD also continuously works to improve the skill of the forecasting models. This year, for preparing the quantitative and probabilistic forecasts for winter season rainfall over the North India, a 4-parameter Principle Component Regression (PCR) has been used.

Troisième hiver le plus chaud depuis 1864
Posted 25 February 2014

A quelques jours de la fin de l'hiver météorologique, la Suisse vivra sans doute son troisième hiver (période du 1er décembre au 28 février) le plus chaud en moyenne nationale depuis le début des mesures en 1864, derrière les hivers 2006/2007 et 1989/1990. Par ailleurs, alors que des précipitations sont encore prévues au Tessin d'ici la fin du mois, la ville de Lugano a connu son hiver le plus humide depuis 1864, dépassant largement le record de l'hiver 1950/1951.


Le froid n'étant toujours pas prévu d'ici la fin du mois, il est déjà possible de tirer quelques conclusions au sujet de l'hiver météorologique 2013/2014 qui s'achèvera dans quelques jours. Ainsi, on peut déjà affirmer de manière très prudente que la Suisse vivra son troisième hiver le plus chaud en moyenne nationale depuis le début des mesures en 1864, derrière les hivers 2006/2007 et 1989/1990. L'écart à la norme 1981-2010 sera probablement compris entre 1.7 et 1.9 degré. >> suite

 

Severe cold and heavy snow in Iran 31 January – 4 February
Posted 18 February 2014

By Parviz Rezazadeh and Ahad Vazife, Senior Forecasters, IRIMO

A cold high with a central pressure of 1055mb surged from Eastern Europe and Russia toward the north of Iran from 31 January 2014. Northerly to north easterly currents were dominant for almost a week. They caused a severe fall in temperature over Iran and Afghanistan and heavy snowfall from the north coastal provinces to the Caspian Sea. With the anchorage effect of a blocking high in the mid and upper levels of the atmosphere over eastern Europe, the northerly to north easterly polar jet stream from 70 to 36 degrees North latitude resulted in an advection of high relative vorticity in the region east of the Black Sea. >> More

The M4 buoy is one of a new generation of weather buoys with the ability to measure maximum wave height as well as the more usual Significant Wave Height.

The Significant Wave Height is defined as the average height of the highest one-third of the waves and that is what our forecasts of wave height refer to.

In general, the highest wave of all will be about twice the Significant Wave Height. >> More

 

Rosetta set to reveal whether water and life were brought to Earth by comets: FMI.
Posted 3 February 2014

The Finnish Meteorological Institute's instruments are on a mission to solve one of the most interesting questions that perplexes humankind: did comets bring water and life to planet Earth? The Finnish Meteorological Institute (FMI) is a strong player in the European Space Association's (ESA) Rosetta Mission. Rosetta is currently en route to the Churyumov-Gerasimenko comet. Rosetta's lander is scheduled to land on the comet's surface on 11 November 2014. The FMI has participated in the design and manufacture of the five scientific measurement instruments that the Rosetta probe is carrying. By European standard's, the FMI's role in this project is therefore a very significant one.  The first instrument to land on the comet will be the FMI-manufactured PP instrument, which is attached to the lander's legs. The instrument will be used to search for water on the surface of the comet. If water, which has the same isotopic composition as that found in the Earth's oceans, is found on the comet's surface, this will demonstrate that water, which has enabled life to form on Earth, has arrived on Earth at least partly on comets. FMI-made measurement instruments will also be used to study such things as the comet's dust and the comet's interaction with solar wind. If organic matter is found in the dust, it is possible that life was also brought to Earth by comets. >> More

 

How unusual were the Antarctic sea ice conditions that trapped a research ship on Christmas Eve 2013? U.S. National Oceanic and Atmospheric Administration
Posted 3 February 2014

January 22, 2014

Extensive sea ice surrounding Antarctica during December 2013 made it even more formidable than usual to access the icy continent. It was in this challenging environment that the Australasian Antarctic Expedition aboard the Russian ship Akademik Shokalskiy became trapped by thick floes of ice in eastern Antarctica’s Commonwealth Bay while following the route navigated by explorer Sir Douglas Mawson a century ago.

The National Snow and Ice Data Center reported that sea ice extent around Antarctica was above average in December. It was the highest December average since 2007 and second highest overall in the satellite record. Throughout 2013, satellites observed record extents for both the annual summer minimum (February) and winter maximum (September). >> More

 

Three-Month Climate Characteristic Expectations of Thailand
Posted 3 February 2014


February: Weather will be rather variable as cool or cold air in the morning, mostly at
Northern and Northeastern parts. Additionally, thunderstorms happen on some days.
March: High pressure air masses from China prevailing to cover the upper Thailand from time
to time will be mostly weak, and some southerly or southeasterly winds cover upper Thailand occasionally. Thus, the upper Thailand will be warm with thick fog in many areas and hot during daytime. However, in many areas of the Northern and Northern parts are still cool or cold in the morning and thunderstorms occur in some areas on some days. >> More

 

Seasonal Outlook for Winter Season (January-March) Rainfall over North India - 2014
Posted 3 February 2014

North India consisting of seven subdivisions (East U.P., West U.P. Uttaranchal,
Haryana, Punjab, Himachal Pradesh, Jammu & Kashmir) receives about 17% of its annual
rainfall during the winter season (January to March). The Jammu & Kashmir in particular
receives about 30% of its annual rainfall during this period. The winter rainfall is very crucial for Rabi crops over the region. It is also crucial for the water management of the region. In view of these reasons, India Meteorological Department (IMD) has been issuing long range forecast outlook for the winter rainfall over north India. IMD also continuously works to improve the skill of the forecasting models. This year, for preparing the quantitative and probabilistic forecasts for winter season rainfall over the North India, a 4-parameter Principle Component Regression (PCR) has been used. Multi Model Ensemble Forecasts based on dynamical models from few important international agencies were also examined for guidance.

Based on the above information, the summary of the operational forecast for 2014 winter
season rainfall over north India is given below: IMD operational forecast for the 2014 winter season (Jan to March) is that the 2014 winter season rainfall over North India is most likely to be below normal (< 85 of the Long Period Average (LPA)). The LPA of the winter rainfall over North India for the period 1951-2000 is 183.1 mm. >> More

The weather in Iceland 2013
Posted 3 February 2014

The weather in Iceland in 2013 was mainly favorable, however, the spring was harsh in the North and East and the summer was on the dull side in the South and West, with precipitation and cloudiness above average. This was the dullest summer of the new century in this area of the country.

The temperature was unusually high during the first two months but for the rest of the year it was closer to the 1961 - 1990 average, relatively coldest in April when persistent snow cover caused problems in the agriculture in the Northeast. An unusually severe but short cold spell hit during the last days of April and the first days of May and resulted in new May minimum temperature records both for the country as a whole and the inhabited areas as well. >>More

 

2013 in Russia the 6th warmest on record: Roshydromet
Posted 20 January

2013 in Russia has become the 6th warmest  in the history of observation since 1891. It was 0.2 °C warmer than 2012, but considerably concedes to the record year 2007. In 2013 almost on the whole territory of Russia the average annual air temperature was higher than normal. This is for the first time since 2007. In 2013  in the south of Eastern Siberia it was colder than usually.  It was 2 °C warmer than usually in the south of the Volga federal district, in Evenkia, in certain areas of the Sea of Okhotsk coast of the Khabarovsk and Kamchatka districts, and also in the north of the European territory: in Karelia, Murmansk region, Novaya Zemlya. On islands in the Kara Sea and Barents Sea the anomaly exceeded 3 °C. The anomaly of temperature in the Arctic in 2013 is less   than in 2012 when  it reached 6…7 °C and more. The  average yearly temperature in the Arctic returned to the level observed  10 years ago. >> More

 

Trinidad and Tobago Met Office breaking new ground with Agro-Met Forecasts
Posted 17 January 2014

In the southwest peninsula of Cedros, one of Trinidad’s driest areas, Jenson Alexander grows the cocoa used for many years by the British chocolate giant Cadbury. Dry conditions mean that he frequently faces bush fires, a challenge compounded by increasing climate variability that makes it difficult to predict when an extended dry season, and the fires that accompany it, are likely to occur.

So in May, when the Trinidad and Tobago Meteorological Service (TTMS) began issuing weather bulletins specifically to keep farmers updated on expected weather conditions, he found a measure of relief. “Before, it was difficult when you were expecting to have rain and [instead] you were having drought…and bush fires,” Alexander told IPS. The 10-day bulletins for farmers that the TTMS issues have considerably reduced the uncertainty, he said. “Now we have updates, we can plan better, if we are having an extended dry season. So bush fires won’t affect us” as they did before, he said. Kenneth Kerr, a climate meteorologist at TTMS, told IPS that “cocoa farmers have indicated that they found the bulletins very useful.” Trinidad boasts some of the finest cocoa in the world and the makers of Cadbury chocolate once owned and operated a cocoa estate in the island. Kerr is one of two meteorologists in Trinidad and Tobago who produce 10-day forecasts geared specifically to the farming community. >> More

 

 

Wetter and warmer year in China: CMA climate bulletin
Posted 17 January 2014

Wetter and warmer conditions with multiple meteorological disasters highlight climate last year, says the annual climate bulletin released by the China Meteorological Administration (CMA) today.

In 2013, the national average precipitation of China is 653.5mm, 4 percent higher than normal years. The average temperature is 10.2 degrees Celsius, 0.6 degrees Celsius higher than normal years, and the fourth warmest year since 1961, said Mr Song Lianchun, Director-general of National Climate Centre at a press conference on January 14 in Beijing.

The Bulletin shows that in 2013, the strongest heat wave since 1951 hit southern China. Northeast China, Northwest China, and Sichuan Basin saw severe heavy rain and floods. The rainfall in Songhua River basin in northeast China was the most since 1951. With more precipitation than normal, Song said due to small coverage and light intensity of the agro-meteorological disasters in major grain growing regions, the weather and climate conditions for agriculture production were generally favorable.

2013 was also a busy year for typhoon, during which there were 31 typhoons formed in northwestern Pacific ocean and South China Sea, 5.5 more than normal years. 9 typhoons made landfall in China, with 2 more than average. Over the year, typhoons caused 199 death, 67 missing and economic loss up to 120 billion Yuan. Warmer ocean, active convection and suitable circulation patterns contributed to the active typhoon season, said Song. >> More

 

Recovery of the ozone layer has begun:Finnish Meteorological Institute
Posted 17 January 2014

The weakening of the ozone layer, which protects the earth from ultraviolet radiation from the sun, has stopped and ozone levels have started to rise. A Finnish and American group of researchers has examined a series of measurements taken by two satellite measuring
instruments. With the help of the instruments on the GOMOS and SAGE II satellites, a combined series of measurements over 27 years has been created. The measurements indicate that a change took place in about 1997. The year is the same when the levels of substances that destroy ozone reached their peak in the ozone layer and started to decline.


"By using complex atmospheric models it is possible to predict that the ozone layer will recover by mid-century", says Research Professor Erkki Kyrölä of the Finnish Meteorological Institute.This positive development indicates that the international Montreal Protocol signed
in 1988, which banned the use of CFC gases which destroy ozone, has been effective.

New heatwave service to forecast extreme heat events: Australia BoM
Posted 17 January 2014

The Bureau of Meteorology is now piloting a new heatwave service to Photo: Feeling the heat? We've just released a pilot heatwave forecast service!     The new service shows the forecast location of heatwaves for the current and next four days across Australia: http://bit.ly/1bPoqyw forecast the onset of extreme heat events. Assistant Director for Weather Services, Alasdair Hainsworth, said the new service complements the Bureau's existing maximum and minimum seven (7) day temperature forecasts across the country."The heatwave service provides a measure of the build-up of 'excess' heat and will provide a more advanced indicator than temperature alone in anticipating the impact of heat stress," Mr Hainsworth said."The pilot service uses a heatwave intensity index that assesses the build up of heat over a
period of time, taking into account the long-term climate of a location and the maximum and minimum temperatures leading up to a heatwave event. >> More
