Recent investigations suggest that the equations ECMWF uses to forecast the global weather may not have to be updated to much more computationally demanding ones as long as the weather model’s horizontal grid spacing is no smaller than 2.8 km.

Rebecca Emerton is part of a team that tries to improve ECMWF’s weather model by looking for the causes of errors. She is also helping the EU’s Copernicus Climate Change Service, which is implemented by ECMWF, to draw up its yearly review of the climate.

Data assimilation is the combination of the latest observations with a short-range forecast to obtain the best possible estimate of the current state of the Earth system. Machine learning can contribute to it by optimising the use of satellite observations.

Over 140 people attended ECMWF’s 20th Workshop on High-Performance Computing in Meteorology in Bologna, Italy, from 9 to 13 October 2023, and nearly 170 registered online. The theme was ‘Diversifying HPC’.

The autumn 2023 issue of the ECMWF Newsletter is now available. As well as news about ECMWF staff and events, it features articles about new developments and the use that can be made of ECMWF products.

The EU’s Destination Earth initiative, implemented by ECMWF, EUMETSAT and ESA, will hold its second User eXchange meeting on 13–14 November 2023 in Bonn, Germany.

Laleh Pouyan tries to minimise the cost while maximising the speed of high-performance computing (HPC) used in weather forecasting. She will present a poster on her work at the ECMWF workshop on HPC in meteorology from 9 to 13 October 2023.

OpenIFS, a supported and easily accessible version of ECMWF’s Integrated Forecasting System (IFS) provided for research and education, is to be upgraded to the latest IFS model cycle by the end of this year.

The European Weather Cloud, a distributed cloud computing infrastructure of ECMWF and EUMETSAT providing access to data and other services from the two organisations, becomes operational on 26 September 2023.

The EU-funded Copernicus Atmosphere Monitoring Service (CAMS), implemented by ECMWF, is working to support a new Global Greenhouse Gas Watch introduced by the World Meteorological Organization.
