AI weather models predict typhoon sparking legal concerns

China's Central Meteorological Office warned Typhoon Bawing may hit the southeast coast. Some bloggers use open-source AI weather models to post typhoon path and rainfall predictions, even offering paid forecasts at about 10 yuan each. China's Meteorological Law bans personal weather forecasts, with violators facing fines up to 50,000 yuan. Experts say AI models like "Fengwu", GenCast, and "Fuxi" have improved accuracy but still struggle with extreme weather due to coarse resolution (about 25 km per grid point).
