EFI and SOT 2 metre temperature over Extended range

Base Time: Thu 26 May 2022 00 UTC T+264 Valid time: Mon 30 May 2022 00 UTC - Mon 06 Jun 2022 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 forecast index (EFI) and Shift of tails (SOT) products can be found in ECMWF Forecast User Guide.

Serving meteorology

International collaboration is fundamental to the work of ECMWF, working with the EU and the meteorological community at large, including the World Meteorological Organization, space agencies, and scientists around the world.

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.
