Report Title: A Global Eddy-Resolving Intelligent Forecasting Large Model for Marine Environment

Speaker: Associate Researcher Xiang Wang

Affiliation: National University of Defense Technology

Time: 16:40-17:20, Saturday, June 7, 2025

Venue: Meeting Room 706, School of Computer Science and Information Engineering, Hefei University of Technology

Report Abstract:

The "Xihe" global marine environment forecasting large model is trained using 25 years of GLORYS12 ocean reanalysis data (1993-2017), ERA5 atmospheric reanalysis data, and sea surface temperature satellite observation data provided by CMEMS. A two-year comparison of forecasting results with international mainstream operational ocean environment numerical forecasting systems such as France's PSY4, Canada's GIOPS, Australia's OceanMPAS and the UK's FOAM shows that the forecasting accuracy of "Xihe" in core indicators such as temperature, salinity and ocean current reaches or even exceeds that of the world's advanced global numerical forecasting operational systems.
