China Unveils First Fengyun Meteorological Satellite Extreme Weather AI Models

People's Daily reported that the first batch of Fengyun meteorological satellite extreme weather artificial intelligence models was officially released at the 2026 Fengyun Satellite User Conference. The release includes an intelligent cloud image interpretation model for typhoons and a nowcasting early warning model for severe convection, aiming to enhance monitoring and early warning capabilities. The typhoon intelligent cloud image interpretation model incorporates multichannel cloud images and related products to automatically analyze typhoon position, structure, intensity, and evolution trends, generating descriptive texts and visual conclusions. Covering 7 categories of typhoon characteristics and integrating over 20 satellite products, it conducts an interpretation every 15 minutes and generates text in 27 seconds. The severe convection nowcasting early warning model utilizes continuous observations from the Fengyun-4 meteorological satellite over the past 2 hours and applies artificial intelligence to forecast cloud image evolution for the next 4 hours while identifying potential severe convection areas, advancing the warning lead time to 4 hours.

In a practical application during Typhoon Surigae, the 26th typhoon of the year, the typhoon interpretation model automatically identified the system and conducted comprehensive analyses of its intensity, wind radius, and precipitation features to support typhoon monitoring and forecasting.
