ECMWF, through its partnerships with EUMETSAT, ESA, the EU and the European Science community has established a leading position for Europe in the exploitation of satellite data for operational numerical weather prediction, and in the exploitation of satellite data for operational seasonal forecasting with coupled atmosphere-ocean-land models.

The National Meteorological Services of Member States and Co-operating States use ECMWF ’ s products for their own national duties, in particular to give early warning of potentially damaging severe weather.

ECMWF ’ s strategy underlines its commitment to maintaining the current rapid rate of improvement of its global medium-range forecasts and products.

In particular, ECMWF ’ s emphasis on the provision of reliable predictions of severe weather can be seen as a key contribution to help society adapt to the dangers and threats associated with global warming.

Also scientists and researchers around the world use ECMWF ’ s forecast products to monitor the environment and analyse climate change.

The ECMWF re-analysis project is a meteorological reanalysis project.

The European Centre for Medium-Range Weather Forecasts ( ECMWF ) is an independent intergovernmental organisation supported by 19 European Member States and 15 Co-operating States.

ECMWF has dramatically improved the accuracy and reliability of weather forecasting, working in collaboration with Member and Co-operating States, the European Union and partners such as the World Meteorological Organization ( WMO ), the European Organisation for the Exploitation of Meteorological Satellites ( EUMETSAT ) and the European Space Agency ( ESA ).

ECMWF continuously endeavours to improve the use of satellite observations for NWP.

The ECMWF is best known in the United States for its global operational forecast model, known officially as the " Integrated Forecast System " but usually known informally as the " ECMWF " or " Euro ".

The ECMWF model is primarily used as comparison against the Global Forecast System, which is based in the United States and is run by the National Centers for Environmental Prediction.

Centers such as ECMWF show instantaneous map of their coverage ; or the Hadley Centre show the coverage for the average of the year 2000.

OSCAR currents are routinely used to evaluate the surface currents in Global Circulation Models ( GCMs ), for example in NCEP Global Ocean Data Assimilation System ( GODAS ) and European Centre for Medium-Range Weather Forecasts ( ECMWF ).

These products are issued twice daily using guidance from the NWS's Global Forecast System ( GFS ) and North American Mesoscale Model ( NAM ), as well as guidance from the European Centre for Medium-Range Weather Forecasts ( ECMWF ), the United Kingdom's Met Office ( UKMET ), the Meteorological Service of Canada, including ensembles.

Surface pressure forecasts are issued three times per day, with temperature and probability of precipitation products issued twice per day, using guidance from the NWS medium range forecast model ( GFS ) as well as models from the European Centre for Medium Range Weather Forecasting ( ECMWF ), the United Kingdom's Meteorology Office ( UKMET ), Canadian model, the Navy NOGAPS model, and ensemble guidance from the GFS, ECMWF, Canadian, and North American Ensemble Forecast System ( NAEFS ).

Since 2006, the HIRLAM cooperation has shifted its focus to the development of meso-scale ( convection-permitting ) numerical weather prediction system ( HARMONIE ) through close collaboration with ALADIN consortium ( led by Meteo France ) and ECMWF ( European Center for Medium-range Weather Forecasting ).

Starting in 1992 with ensemble forecasts prepared by the European Centre for Medium-Range Weather Forecasts ( ECMWF ) and the National Centers for Environmental Prediction, model ensemble forecasts have been used to help define the forecast uncertainty and to extend the window in which numerical weather forecasting is viable farther into the future than otherwise possible.

* ECMWF: European Centre for Medium-Range Weather Forecasts

Today ensemble predictions are commonly made at most of the major operational weather prediction facilities worldwide, including the National Centers for Environmental Prediction ( US ), the European Centre for Medium-Range Weather Forecasts ( ECMWF ), the United Kingdom Met Office, Meteo France, Environment Canada, the Japanese Meteorological Agency, the Bureau of Meteorology ( Australia ), the China Meteorological Administration, the Korea Meteorological Administration, and CPTEC ( Brazil ).

The designated TIGGE archive centers include the Chinese Meteorological Administration ( CMA ), The European Center for Medium-Range Weather Forecasts ( ECMWF ), and The National Center for Atmospheric Research ( NCAR ).

ECMWF is renowned worldwide as providing the most accurate medium-range global weather forecasts to 15 days and seasonal forecasts to 12 months.

ECMWF uses the computer modelling technique of numerical weather prediction ( NWP ) to forecast the weather from its present measured state.

ECMWF has pioneered an innovative approach known as reanalysis, which involves feeding weather observations collected over decades into a NWP system to recreate past atmospheric, sea-and land-surface conditions over specific time periods to obtain a clearer picture of how the climate has changed.

The ECMWF strategy puts the early warning of severe weather as its principal goal.

The ECMWF model runs every 12 hours and forecasts out to 10 days.

To date, and with support from Europe's National Meteorological Services and the European Commission, ECMWF has conducted two major reanalyses of the global atmosphere: the first ECMWF re-analysis ( ERA-15 ) project generated reanalyses from December 1978 to February 1994 ; the ERA-40 project generated reanalyses from September 1957 to August 2002.

Nonetheless, a limited amount of output from the model has been publicly released through both the ECMWF and various sites.

Currently, the output from the ECMWF, UK Met Office ( UKMO ), CMA, Japan Meteorological Agency ( JMA ), National Centers for Environmental Prediction ( NCEP-USA ), Meteorological Service of Canada ( CMC ), Bureau of Meteorology Australia ( BOM ), Centro de Previsao Tempo e Estudos Climaticos Brazil ( CPTEC ), Korea Meteorological Administration ( KMA ), and MeteoFrance ( MF ) global models, totaling 440 GB / day, is moved at up to 30 GB / hour to NCAR ( Realtime Statistics ).

ECMWF makes significant contributions to support research on climate variability.

However, unlike the GFS, which is in the public domain under provisions of United States law, the ECMWF model is proprietary and copyrighted.

ECMWF can contribute to the development of strategies to mitigate and adapt to climate change.

Since ECMWF runs a wave model, there are also predictions of coastal waves and storm surges in European waters which can be used to provide warnings.

Currently the ECMWF runs at resolution as opposed to the scale used by typical climate models.

Now, although the roots of the mystery story in serious literature go back as far as Balzac, Dickens, and Poe, it was not until the closing decades of the 19th century that the private detective became an established figure in popular fiction.

At first glance this appears strange: of all people, was not America founded by rugged individualists who established a new way of life still inspiring `` undeveloped '' societies abroad??

It was established in a couple of buildings in the shopping district, with only a few professors, but all eminent men, and a few hundred eager students housed in nearby dwellings.

Her mother was a good manager and established a millinery business in Milwaukee.

It was therefore not until the publication of J.H. Round's `` The Settlement Of The South And East Saxons '', and W.H. Stevenson's `` Dr. Guest And The English Conquest Of South Britain '', that a scientific basis for place-name studies was established.

He could no longer build anything, whether a private residence in his Pennsylvania county or a church in Brazil, without it being obvious that he had done it, and while here and there he was taken to task for again developing the same airy technique, they were such fanciful and sometimes even playful buildings that the public felt assured by its sense of recognition after a time, a quality of authentic uniqueness about them, which, once established by an artist as his private vision, is no longer disputable as to its other values.

So the pattern was established.

It was a quarter of seven when the crowd washed me up among the other gallants who had established the Astor steps as the beach-head from which to launch their night of merrymaking.

He took advantage of the antagonism between aggressive assertiveness and anxiety and found a relatively rapid disappearance of anxiety when the former attitude was established.

Since the writer had established this democratic procedure in the beginning he had to go along with their decision -- after, of course, pointing out whether he thought their decision was a wise or an unwise one.

Although the Taylor Scale was designed as a group testing device, in this study it was individually administered by psychologically trained workers who established rapport and assisted the children in reading the items.

Though little democracy had ever been practised in this region, and much of it was still ruled by feudalistic means, it was taken for granted that at least the forms of Western democracy would be established in this area and Western capitalism preserved within it.

Now, with virtually every writer, not only was the European origin of public law acknowledged as a historical phenomenon, but the rules thus established by the advanced civilizations of Europe were to be imposed on others.
