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.
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.
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.
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.
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).
Louise Arnal is a scientist with a lifelong love of art. Here she explores the relationship between art and science and talks about her involvement in a number of SciArt projects.
The Copernicus Atmosphere Monitoring Service (CAMS) and EUMETSAT have teamed up to produce a Massive Open Online Course (MOOC) – Mark Parrington discusses its production and launch.
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.
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.
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.
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.
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.
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.
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.
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.
As WMO's Year of Polar Prediction gets well under way, Irina Sandu and Peter Bauer discuss the challenges of forecasting in the polar regions and highlight the priorities for ECMWF.
The issue of scalability will feature as the headline topic at this year's ECMWF high-performance computing (HPC) workshop in September. Here Peter Bauer, head of ECMWF’s Scalability Programme, talks about what is perhaps the biggest revolution in numerical weather prediction since computer-based forecasts began.
Erik Andersson, Deputy Director of the Forecast Department, will be presenting ECMWF products and what they can deliver at InterMet Asia, the region's largest assembly of meteorology professionals.
Gianpaolo Balsamo discusses the importance of two-way coupling between the atmosphere and Earth’s surface, and how humans are altering these interactions. He shares his drive and excitement about bringing recent research developments into operational use.
