Revolutionary AI Model FengShun-CSM Enhances Climate Forecasting

In May 2025, a team of researchers introduced FengShun-CSM, an artificial intelligence-driven Climate System Model designed to deliver 60-day global daily forecasts across 29 critical variables encompassing the atmosphere, ocean, land, and cryosphere. This model has demonstrated superior performance compared to the European Centre for Medium-Range Weather Forecasts (ECMWF) subseasonal-to-seasonal (S2S) model, particularly in predicting precipitation patterns, land surface conditions, and oceanic components. The enhanced accuracy is largely attributed to its improved representation of intra-seasonal variability modes, notably the Madden-Julian Oscillation (MJO).

The MJO is a significant element of intra-seasonal variability in the tropical atmosphere, characterized by an eastward-moving pattern of increased and decreased rainfall. Each cycle lasts approximately 30 to 60 days and influences global weather patterns, including monsoons and tropical cyclones. Accurate representation of the MJO is crucial for improving subseasonal weather forecasts.

FengShun-CSM's ability to effectively capture the dynamics of the MJO offers several societal benefits. Improved forecasts can lead to better preparedness for extreme weather events, reducing potential damage and loss of life. Accurate oceanic predictions aid in monitoring and protecting marine biodiversity. Reliable climate forecasts enable farmers to make informed decisions, optimizing planting and harvesting schedules.

The success of FengShun-CSM validates the feasibility of developing AI-powered climate system models. This achievement marks a transformative shift in Earth system modeling, suggesting that machine learning technologies can effectively simulate complex climate interactions.

The introduction of FengShun-CSM represents a significant advancement in climate modeling, offering more accurate and extended forecasts. Its superior performance, particularly in representing the MJO, underscores the potential of AI-driven models in addressing complex climate challenges and their societal impacts.
