Experts review ocean surface observations for NWP 29 January 2018 More than 50 ocean and data assimilation experts came together at ECMWF from 22 to 25 January to discuss the way forward for the use of observations of sea-surface temperature (SST) and sea ice in numerical weather prediction (NWP) and climate applications.
4D-Var anniversary symposium held at ECMWF 26 January 2018 Developing a 4D variational data assimilation system was one of ECMWF’s biggest-ever projects. A symposium to mark the 20th anniversary of the operational implementation of 4D-Var took place at the Centre on 26 January.
Winter 2017/18 Newsletter published 19 January 2018 The winter 2017/18 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.
Ocean coupling in tropical cyclone forecasts 11 January 2018 Tropical cyclones are one of the deadliest weather phenomena. One of the avenues being pursued at ECMWF to improve forecasts of tropical cyclones is to better take into account interactions between the ocean and the atmosphere during the forecast period.
2017 extends exceptionally warm period, first complete datasets show 4 January 2018 The first complete temperature datasets for 2017 show that last year was the third in a row of exceptionally warm years, the Copernicus Climate Change Service (C3S) implemented by the European Weather Centre (ECMWF) can announce.
ECMWF at the 2018 AMS Annual Meeting 2 January 2018 ECMWF will be at the American Meteorological Society (AMS) Annual Meeting in Austin, Texas, from 7 to 11 January. Find out when our staff are presenting and when they will be available at our booth.
News highlights of 2017 22 December 2017 The year started with a bang when ECMWF Copernicus reanalysis data showed that 2016 had been the warmest year on record. Other milestones included the decision to build a new data centre in Bologna, a major model upgrade and the implementation of a new seasonal forecasting system.
Symposium speakers hail ECMWF scientist’s lifetime achievements 18 December 2017 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 engages with Python community 12 December 2017 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.
Symposium marks leading ECMWF scientist’s lifetime achievements 8 December 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.
Council lecture on 25 years of ensemble prediction 7 December 2017 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.
Shaping the future of supercomputing in numerical weather prediction 4 December 2017 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.
Reanalysis takes centre stage as climate change service spreads its wings 27 November 2017 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.
20 years of 4D-Var: better forecasts through a better use of observations 20 November 2017 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.
How to model convection and its impact on weather 13 November 2017 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.
New seasonal prediction system SEAS5 brings better El Niño forecasts 10 November 2017 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.
Experts to explore global modelling at resolutions under 10 km 2 November 2017 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.
