    ECMWF’s new seasonal prediction system (SEAS5) brings better forecasts, especially for El Niño/La Niña events. Forecasts are also more detailed thanks to much greater horizontal resolution.

  • 2 November 2017

    More than 50 scientists will meet at ECMWF from 13 to 16 November to discuss the modelling of atmospheric processes across the globe at ‘grey zone’ resolutions of a few kilometres or less.
