EFI and SOT 2 metre temperature over Extended range
Base Time: Wed 29 Nov 2023 00 UTC T+288 Valid time: Mon 04 Dec 2023 00 UTC - Mon 11 Dec 2023 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.
Forecast charts and data
We provide current forecasts, climate reanalyses and specific datasets. These are available via the web, point-to-point dissemination, data servers and broadcasting.
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.
Researchers, WMO members, commercial users and satellite data providers can gain access to ECMWF forecast products under one of our various license agreement types.
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.
