    ECMWF will be at the American Meteorological Society (AMS) Annual Meeting in Austin, Texas, from 7 to 11 January. Find out when our staff are presenting and when they will be available at our booth.

  • News highlights 2017
    22 December 2017

    The year started with a bang when ECMWF Copernicus reanalysis data showed that 2016 had been the warmest year on record. Other milestones included the decision to build a new data centre in Bologna, a major model upgrade and the implementation of a new seasonal forecasting system.

  • Adrian Simmons
    18 December 2017

    Speakers at a symposium held at ECMWF on 8 December outlined the remarkable contributions to numerical weather prediction (NWP) made by Adrian Simmons in the course of a career spanning five decades.

  • Visualisation of Hurricane Irma
    4 December 2017

    Radical changes to prepare weather forecasting systems for the exascale era of supercomputing are under way. Now there are plans for a major international project to help complete this revolution.

  • 5th International Conference on Reanalysis in Rome, November 2017
    27 November 2017

    After a successful conference on climate reanalysis in Rome, the EU’s Copernicus Climate Change Service (C3S) being implemented by ECMWF is getting ready to make reanalysis results available to wider audiences.

  • 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.
