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.

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.

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.

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.

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.

The autumn 2017 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.

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.

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.

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.

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.
