  • Diagram illustrating the principle of 4D-Var
    20 November 2017

    Twenty years ago ECMWF added an extra dimension – time – to the assimilation of observational data into weather models. This pioneering ‘4D-Var’ technique has led to substantial improvements in the Centre’s forecasts.

  • Towering convective clouds
    13 November 2017

    Convection is one of the small-scale atmospheric processes at the heart of the workshop ‘Shedding light on the greyzone’ taking place at ECMWF from 13 to 16 November. Convection specialist Peter Bechtold explains why.

  • SEAS5 2-metre temperature forecast chart
    10 November 2017

    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.

  • Numerical weather prediction grid
    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.

  • Emma Pidduck
    26 October 2017

    Supporting ECMWF’s diverse range of users requires know-how in weather science, data handling and consultancy. Emma Pidduck from ECMWF’s Data Services team has what it takes.

  • ECMWF Newsletter 153 cover

  • Large cloud
    17 October 2017

    Over 90 scientists from European national meteorological services and ECMWF came together at the Centre from 2 to 5 October 2017 to talk about convection and other topics in limited-area modelling.

  • ERA5 reanalysis of the Great Storm of 1987
    16 October 2017

    A new climate reanalysis produced by the ECMWF-run Copernicus Climate Change Service (C3S) has reconstructed the Great Storm that hit Britain in October 1987 in much more detail than was possible in the 1980s.

  • Sentinel-5P artist's impression
    13 October 2017

    The Sentinel-5P satellite launched on 13 October 2017 will make a vital contribution to the ECMWF-run Copernicus Atmosphere Monitoring Service (CAMS) by measuring the composition of the atmosphere.

  • Melt ponds on sea ice
    9 October 2017

    A workshop on observations and data assimilation of sea-surface temperatures and sea ice will take place at ECMWF from 22 to 25 January 2018. Registration is still open until 15 October.
