Advancing global NWP through international collaboration

Multi-parameter EFI (24-h up to valid time)

This chart shows where the ENS system expects anomalous weather to occur using symbols - pink for wind and green for rain, and shading for the temperature.
The basis for the symbols is the Extreme forecast index (EFI), which compares the ENS distributions from a particular ENS run with the model climate.
ENS mean of Mean sea level pressure contours are overlaid to aid the interpretation.

Detailed description of EFI products can be found in ECMWF Forecast User Guide.

We provide current forecasts, climate reanalyses and specific datasets. These are available via the web, point-to-point dissemination, data servers and broadcasting.

Cycle Upgrade 47r2

Highlighted tweet

ECMWF has implemented an upgrade of its Integrated Forecasting System, including a move from double to single precision and an increase in the vertical resolution of ensemble forecasts. #IFS47r2 #newfcsystem Find out more here: https://www.ecmwf.int/en/about/media-centre/news/2021/forecast-upgrade-i...

Datasets

Forecasts, analyses, climate re-analyses, reforecasts and multi-model data are available from our archive (MARS) or via dedicated data servers or via point-to-point dissemination.

Accessing forecasts

Researchers, WMO members, commercial users and satellite data providers can gain access to ECMWF forecast products under one of our various license agreement types.

Workshops and education

Education is a key element of our work at ECMWF, enabling our partners to get the most from ECMWF's services and develop an advanced understanding of forecasting.

ECMWF lecture theatre

ECMWF workshops are open to the worldwide meteorological community, though some training is restricted to member states.
