China has achieved a significant technological breakthrough with the official launch of Fengyuan V1.0, a pioneering artificial intelligence meteorological model unveiled on December 19, 2025, in Xiong’an, Hebei Province. This open-source platform represents China’s first end-to-end scientific model base with fully independent intellectual property rights, marking a transformative advancement in weather forecasting capabilities.
Developed through collaboration between the Chinese Academy of Meteorological Sciences and the Xiong’an Institute of Meteorological Artificial Intelligence, Fengyuan V1.0 operates as a unified, large-scale AI system that manages the entire scientific data pipeline. The model’s architecture enables direct generation of global weather predictions from raw observational data, bypassing traditional forecasting limitations.
Chief Scientist Wang Yaqiang of the Chinese Academy of Meteorological Sciences revealed the ambitious roadmap for Fengyuan, stating: ‘Our long-term vision involves evolving this into an open forecasting system driven entirely by observational data with integrated multi-sphere coupling capabilities.’ The model’s open-source nature is strategically designed to consolidate global research and development efforts, ultimately providing robust theoretical and technical foundations for operational forecasting once maturity testing is complete.
Deputy Administrator Cao Xiaozhong of the China Meteorological Administration emphasized the model’s critical applications in extreme weather detection, particularly for short-term imminent weather events. The administration plans to develop specialized vertical AI meteorological models targeting strategic sectors including the low-altitude economy, energy infrastructure, logistics networks, and health meteorology to better support economic and social development objectives.
Concurrently, upgraded versions of complementary meteorological AI systems—Fengqing, Fenglei, and Fengshun—were released alongside the inauguration of a joint Earth System AI Forecasting laboratory established between Fudan University and the Xiong’an Institute. The launch ceremony also highlighted China’s commitment to international collaboration, with plans to promote meteorological AI applications among Belt and Road Initiative partner nations and strengthen partnerships between leading AI innovation teams worldwide.
