    The Oak Ridge Leadership Computing Facility in the US is home to “Summit”, the world’s fastest computer. After his recent trip there, Nils Wedi discusses some of the latest advances in supercomputing and considers their application to numerical weather prediction.

  • 3 May 2019

    PhD student Sam Hatfield discusses how he and colleagues built a table-top supercomputer and used it to produce demonstration weather forecasts with OpenIFS. It's a system that is proving fascinating to the public as well as benefiting Sam's research.

  • 8 April 2019

    Peter Bauer discusses recent ground-breaking work with a high-resolution version of the IFS running on some of the most powerful computers in the world, to see what speed-up can be achieved. He also takes a look back at early experiments from the 1980s.

  • 12 March 2019

    Angela Benedetti (ECMWF) and Peter Knippertz (KIT) explain how the EU-funded DACCIWA project collected new data in West Africa to investigate the causes and effects of air pollution, examining for the first time the entire chain of natural and human-made emissions.

  • 29 January 2019

    In this blog, Dr Frédéric Vitart discusses a book on recent progress and challenges in extended-range forecasting, which he has co-edited with Andrew Robertson (IRI).

    Irina Sandu from ECMWF and Annelize van Niekerk from the UK Met Office discuss their recent work in which kilometre-scale simulations are used to investigate the impact of complex orography on the atmosphere.

  • 10 October 2018

    Sami Saarinen, one of the organisers of the 18th Workshop on High-Performance Computing in Meteorology at ECMWF from 24 to 28 September 2018, goes back over some of the highlights from 41 talks, two panel discussions and a vendors' exhibition.

  • 24 September 2018

    As ECMWF’s 18th workshop on high performance computing in meteorology gets under way in Reading, Wilco Hazeleger, Director of the Netherlands eScience Center and keynote speaker, shares his excitement about the computational and data challenges ahead for the Earth sciences.

  • 10 September 2018

    As ECMWF's first Summer of Weather Code (ESoWC) comes to an end, Julia Wagemann describes how this online collaborative programme is helping ECMWF develop new and innovative software.

  • 24 August 2018

    Mark Rodwell discusses innovative diagnostics which are identifying atmospheric flow types that may lead to poor forecast performance. Such diagnostics can help to prioritise modelling efforts on aspects which might be expected to lead to the largest forecasting improvements.

  • 6 August 2018

    At ECMWF we are very excited about the prospect of using the novel space-based wind profile information of Aeolus to improve our weather forecasts. We are proud to take a significant role in the operational Ground Segment processing and in the expert teams that will work on achieving a useful wind product.

  • 16 July 2018

    The next few years will see a more diverse range of computer architectures and vendors than we’ve enjoyed for over a decade. Simon McIntosh-Smith, a Professor of High Performance Computing from the University of Bristol who collaborates with ECMWF, explains the challenges and opportunities this will bring to the numerical weather forecasting community.

  • 5 June 2018

    Rebecca Emerton discusses her work to develop new GloFAS seasonal forecasts of river flow which have the potential to give even earlier warnings of flood and drought risk around the globe.
