ECMWF Fellow explores post-processed ensemble forecasts
Prof. Sándor Baran became an ECMWF Fellow in January 2021. Since then he has worked on post-processing a range of ECMWF ensemble forecasts to increase their skill.

Model upgrade increases skill and unifies medium-range resolutions
An upgrade of ECMWF’s Integrated Forecasting System to Cycle 48r1 on 27 June has substantially improved the skill of the Centre’s weather predictions and has increased the resolution of medium-range ensemble forecasts.
ECMWF Annual Report 2022 available online
The ECMWF Annual Report 2022 is now available online, reviewing progress towards the goals set out in our ten-year Strategy under the pillars of ‘Science and technology’, ‘Impact’, and ‘Organisation and people’.
Copernicus records first June breach of 1.5°C climate threshold
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
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
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
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
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
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
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.
