“Fengyu” of CMA, a full-chain AI forecasting model for space weather released
At Meteorological Forum at 2025 World Artificial Intelligence Conference (WAIC) --AI-powered Meteorology for Early Warnings for All, "Fengyu" of the China Meteorological Administration (CMA), the world's first full-chain AI forecasting model for space weather, is officially unveiled.
The R&D of "Fengyu" is headed by National Satellite Meteorological Center (National Center for Space Weather) of CMA (hereinafter referred to as "the Centre"), in collaboration with Nanchang University and Huawei Technologies Co., Ltd.

To tackle the impacts of solar storms on global satellite communications, navigation, and critical infrastructure, "Fengyu" caters to the demands of future deep space exploration and orbital safety. It breaks through the technological bottlenecks of traditional numerical models in terms of timeliness and efficiency.
It has become the first AI forecasting model for space weather covering the full chain of the solar wind, magnetosphere, and ionosphere.
"Fengyu" pioneers a full-chain training model and pluggable architecture. It simulates the solar wind, magnetosphere, and ionosphere separately and achieves the collaborative optimization of multi-region models through an intelligent coupling optimization mechanism.

It can not only more realistically reproduce how the solar wind impacts the Earth's surrounding environment, but also depicts the complex interactions between the magnetic field and ionosphere. This enhances the prediction accuracy in each region and the stability of extreme event forecasting, providing new technological means for complex space weather intelligent forecasting.

The testing has shown that "Fengyu"s prediction of major magnetic storms in the past two years is more accurate than existing methods, and its prediction performance in the ionosphere region is particularly outstanding, with the error in predicting global Total Electron Content (TEC) generally controlled within around 10%.
"Fengyu" supports multiple practical application scenarios, and has submitted to 11 national invention patents.
Mr. WANG Jinsong, Director General of the Centre, who headed the R&D of "Fengyu", expressed that the launch of "Fengyu" marked a breakthrough of China's space weather monitoring and early warning capabilities. In the future, it will fully give full play to the benefits of space weather operational applications, advance the high-quality development of space weather operation, and contribute meteorological expertise to the exploration of the universe and the starry sky.
