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.

C3S forecast for December-January-February from November 2022

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.

EUMETSAT's MTG-I1 satellite

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.

Mean daily river discharge 1980 to 2019 from GloFAS v4.0

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 COP27

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.

MOOC Machine Learning in Weather & Climate illustration

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.

ECMWF Newsletter 173

Autumn 2022 Newsletter published

The autumn 2022 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.

Cracks in Arctic sea ice

nextGEMS probes km-scale resolutions in the Integrated Forecasting System

ECMWF is testing what needs to be done to improve the realism of global km-scale weather simulations. As part of the nextGEMS project, it is looking into modelling sea ice cracks in the Arctic and fixing water and energy budget imbalances.

Tim Palmer

Symposium for Prof. Tim Palmer to take place on 5 and 6 December

On 5 and 6 December 2022, ECMWF and the University of Oxford will hold a symposium to celebrate the career of Tim Palmer, whose work has been profoundly linked to ECMWF’s ensemble prediction system.
