ECMWF is taking part in this year’s Annual Meeting of the European Meteorological Society (EMS), 7 to 12 September, in Ljubljana (Slovenia) and online. This event is an opportunity to discuss our work with scientists from across the world. Our staff are participating in a broad range of sessions, covering topics such as data visualisation for climate science, harnessing artificial intelligence (AI), smart afforestation, and more.
The thematic focus of the 2025 EMS Annual Meeting is the transformative power of AI and machine learning (ML) in enhancing weather and climate prediction, environmental monitoring and meteorological research and applications.
European Meteorological Society awards
ECMWF Director-General Florence Rabier and the Anemoi Framework on machine learning, in which ECMWF plays a leading role, will each receive a prestigious award from the EMS during the Annual Meeting.
Florence Rabier will receive the EMS Silver Medal 2025, and the Anemoi Framework, a European collaboration to create ML weather forecasting systems, will receive the EMS Technology Achievement Award 2025.

We will be present from Monday to Thursday at our booth, located in the central entrance foyer of the conference centre “Cankarjev dom”.
