EFI and SOT 2 metre temperature over Extended range

Base Time: Thu 16 Sep 2021 00 UTC T+264 Valid time: Mon 20 Sep 2021 00 UTC - Mon 27 Sep 2021 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.

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.
