July 27 news, in yesterday's 2025 World Conference on Artificial Intelligence meteorological special meeting, led by the National Satellite Meteorological Center (National Space Weather Monitoring and Warning Center) (Note: hereinafter referred to as "Satellite Center"), joint Nanchang University, Huawei Technologies Co. Artificial Intelligence Forecasting Model --"your appearance (honorific)", officially released.
In order to cope with the impact of solar storms on global satellite operations, radio communications, satellite navigation and positioning and other critical infrastructures, "Fengyu" is geared towards the demand for space weather protection and breaks through the technical bottleneck of traditional numerical models in terms of arithmetic power consumption and real-time response.Becoming the first international space weather artificial intelligence forecast model covering the entire chain of solar wind, magnetosphere and ionosphere.
"Fengyu" pioneered the chain training model and pluggable architecture.In addition, by modeling the solar wind, magnetosphere and ionosphere separately and realizing the synergistic optimization of multi-region models through an intelligent coupling optimization mechanism, the model can not only reproduce more realistically how the solar wind affects the Earth's space environment, but also depict the complex interactions between the magnetosphere and the ionosphere, improve the prediction accuracy of each region and the stability of extreme event prediction, and provide a new technological means for the intelligent forecasting of complex space weather.
"Feng Yu" has made breakthroughs in short-range forecasting and response to extreme events.In a year-long prediction performance test, Feng Yu demonstrated excellent 24-hour short-range prediction capability in all regions of the solar wind, magnetosphere and ionosphereTests have shown that the forecasting performance of "Feng Yu" for large magnetic storms in the past two years is more accurate than the existing methods. Tests have shown that the prediction of large magnetic storms in the past two years by Fengyu is more accurate than the existing methods, and the prediction performance in the ionosphere region is particularly outstanding, with the prediction error of the total global electron density basically controlled at about 10%.
"Feng Yu" can support a variety of application scenarios, and has applied for 11 national invention patents.
Wang Jinsong, the lead developer of "Feng Yu" and director of the Satellite Center, said that the release of "Feng Yu" marks a new breakthrough in China's space weather monitoring and early warning capabilities, and in the future, it will give full play to the benefits of operational space weather applications, and promote the high-quality development of space weather work. In the future, we will give full play to the benefits of operational space weather applications, promote the high-quality development of space weather work and contribute meteorological wisdom to the exploration of the universe.
