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.

ECMWF is stepping up its efforts to provide processing and visualisation options in the Python programming language. To engage with the developer community, the Centre hosted a Python frameworks workshop on 28 and 29 November 2017.

A symposium to mark the decisive contributions of ECMWF scientist Adrian Simmons to numerical weather prediction and climate science took place at the Centre on 8 December.

ECMWF Lead Scientist Roberto Buizza delivered a lecture on ’25 years of ensemble prediction’ on 7 December, on the occasion of the 91st Council meeting. A recording of the lecture can be viewed online.

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.

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.

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.
