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, 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.

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.

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 ).

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, the Ensemble Prediction System, uses singular vectors to simulate the initial probability density, while the NCEP ensemble, the Global Ensemble Forecasting System, uses a technique known as vector breeding .< ref name =" Toth ">

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

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.

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

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.

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

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 was established in 1975, in recognition of the need to pool the scientific and technical resources of Europe ’ s meteorological services and institutions for the production of medium-range weather forecasts and of the economic and social benefits expected from it.

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

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

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.

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 ).

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

ECMWF makes significant contributions to support research on climate variability.

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

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

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

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.

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

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

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