Copernicus records first June breach of 1.5°C climate threshold 15 June 2023 The global-mean surface air temperature was more than 1.5°C above pre-industrial levels in early June, which is a first for a summer month, the EU-funded Copernicus Climate Change Service (C3S) implemented by ECMWF has said.
Forecasts show growing El Niño event 12 June 2023 Forecasts assembled by the EU’s Copernicus Climate Change Service implemented by ECMWF predict a growing El Niño event, which is a prolonged period of abnormally high sea-surface temperatures in the tropical Pacific Ocean.
Developing an urban scheme for the IFS 30 May 2023 The urban environment will for the first time be considered in ECMWF’s Integrated Forecasting System (IFS) from next year. This is important because in cities temperatures are often elevated compared to their surroundings.
Supercomputing and cloud resources available for weather and climate research 22 May 2023 Researchers from any organisation in ECMWF Member States are invited to apply for computing resources as part of the Special Project framework. For projects to start at the beginning of 2024, requests should be submitted before 30 June 2023.
Extended-range forecasts to be recast in next model upgrade 16 May 2023 In the next upgrade of ECMWF’s Integrated Forecasting System, extended-range forecasts will have 101 instead of 51 ensemble members and will run more frequently than before, at a consistent horizontal resolution of 36 km.
Machine learning comes to the fore at EGU conference 5 May 2023 Machine learning was a prominent theme to which ECMWF scientists contributed at the European Geosciences Union (EGU) General Assembly 2023, while other issues related to weather forecasting across different timescales were represented, too.
ECMWF’s next model upgrade to provide better initial conditions for weather forecasts 2 May 2023 Cycle 48r1 of ECMWF’s Integrated Forecasting System, which is to become operational this summer, will include extensive changes to the way the initial conditions of weather forecasts are established.
Spring 2023 Newsletter published 21 April 2023 The spring 2023 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.
European climate marked by heat and drought in 2022 – report 20 April 2023 The climate in Europe in 2022 was marked by extreme heat and widespread drought, according to a report published by the EU-funded Copernicus Climate Change Service implemented by ECMWF.
Four key ECMWF events in 2023 5 April 2023 ECMWF’s events programme in 2023 includes four key meetings between June and October: Using ECMWF’s Forecasts, the Annual Seminar, an event on atmospheric river reconnaissance, and one on high-performance computing in meteorology.
Three research projects to improve ECMWF’s Copernicus services 29 March 2023 January 2023 marked the start of three EU-funded research projects to further develop the EU’s Copernicus Climate Change Service and Copernicus Atmosphere Monitoring Service implemented by ECMWF: CERISE, CAMEO and CORSO.
The future of weather, climate and water across generations 23 March 2023 On World Meteorological Day, ECMWF Director of Forecasts Florian Pappenberger reflects on the WMO’s critical role and the importance of international collaboration for the future of weather, climate and water across generations.
Destination Earth demonstration products to be ready by mid-2024 8 March 2023 ECMWF will ensure that the EU’s Destination Earth initiative has completed the first steps in developing highly accurate replicas of Earth to facilitate action on climate change and environmental extremes by mid-2024.
New data show a wetter and warmer Arctic 28 February 2023 Scientists from the EU’s Copernicus Climate Change Service (C3S) implemented by ECMWF have observed major changes in Arctic precipitation, air temperature and sea-ice coverage over the most recent three decades. Reanalysis enables a new focus on the Arctic climate.
Upgrade of forecasts is at the centre of our plans for 2023, says DG 13 February 2023 An upgrade of the Integrated Forecasting System (IFS) to Cycle 48r1 is at the centre of our plans for 2023, ECMWF Director-General Florence Rabier has said in an interview that previews the Centre’s activities this year.
How to monitor observations to ensure the best possible forecasts 7 February 2023 Numerical weather predictions rely on observations to help establish the initial conditions of forecasts as accurately as possible. Mohamed Dahoui monitors weather observations at ECMWF to ensure they are of good quality.
