EFI and SOT 2 metre temperature over Extended range

Base Time: Thu 26 Nov 2020 00 UTC T+768 Valid time: Mon 21 Dec 2020 00 UTC - Mon 28 Dec 2020 00 UTC

EFI index (shading) provides specialized forecast guidance for anomalous or extreme weather events by comparing the ENS forecast with the model climate for the chosen location, time of year and forecast lead time.
The SOT index complements EFI by providing information about how extreme an extreme event might be.

Detailed description of Extended range Extreme foreacst index (EFI) and Shift of tails (SOT) products can be found in ECMWF Forecast User Guide.

Barbados clouds

Clouds blowing (in) the wind

ECMWF Fellow Louise Nuijens is daydreaming about a field campaign in Barbados earlier this year. Working with us, she is analysing the observations that were collected there, to understand how clouds affect and are affected by the wind.

Highlighted tweet

Full documentation is now available for Cycle 47r1 of ECMWF’s Integrated Forecasting System (IFS), which became operational in July this year. IFS documentation #IFS47r1

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.
