The growing role of machine learning at ECMWF
Machine learning is entering many aspects of weather forecasting. At ECMWF, a team of three people is supporting these activities. They expect machine learning to continue to play a growing role in weather forecasting.
The year 2022 was the second warmest on record in Europe
The year 2022 was the second warmest on record in Europe, and the summer of 2022 was the hottest in Europe, data released by the European Union’s Copernicus Climate Change Service (C3S) run by ECMWF show.
News highlights of 2022
ECMWF news highlights of 2022 include forecast data updates; projects and workshops to drive forward weather science; and news from the EU-funded services implemented by ECMWF.
25 years of 4D-Var: how machine learning can improve the use of observations
Twenty-five years ago, ECMWF introduced ‘4D-Var’ to the assimilation of observational data into its weather model. Changes worked on over the last few years include reducing the effects of model biases using machine learning techniques.
How models predict a possible outline of winter weather in Europe
ECMWF produces not just weather forecasts 15 days ahead but also forecasts for weeks and seasons ahead. The latter contribute to multi-centre predictions provided by the EU’s Copernicus Climate Change Service run by ECMWF.
New geostationary satellite to bring benefits for ECMWF’s forecasts
EUMETSAT is planning to launch a new geostationary satellite in December that provides more frequent and higher-resolution images than its predecessor and carries a new instrument to observe lightning flashes.
Copernicus Emergency Management Service releases GloFAS v4.0 hydrological reanalysis
A new, substantially upgraded hydrological reanalysis dataset of the Global Flood Awareness System from 1980 to July 2022 has been produced by the Joint Research Centre of the European Commission in collaboration with ECMWF and released as part of the Copernicus Emergency Management Service.
ECMWF at the United Nations COP27 Climate Change Conference
ECMWF is making a wide-ranging contribution to 27th United Nations Climate Change Conference (COP27), joining high-level interventions at the UN-led Earth Information Day and an event presenting the Systematic Observations Financing Facility (SOFF). We are also involved in side events for the European Union’s Copernicus programme and Destination Earth initiative.
ECMWF launches Massive Open Online Course on Machine Learning in Weather and Climate
Registration is now open for a new Massive Open Online Course (MOOC) on Machine Learning in Weather and Climate to be launched in January 2023.
