Chinese researchers have unveiled a new artificial intelligence tool, the FengShun-CSM, that significantly extends the reach of global weather forecasting. Capable of predicting key climate conditions up to 60 days in advance, this model promises valuable insights for disaster preparedness and agricultural planning.
What Is the FengShun-CSM?
FengShun-CSM is an AI-driven climate model jointly developed by the Shanghai Academy of Artificial Intelligence for Science and Fudan University. Unlike traditional forecasting methods that rely on complex physical equations, FengShun-CSM applies machine learning to vast amounts of historical and real-time weather data. This approach enables it to predict variables such as rainfall and land surface conditions with improved efficiency and speed.
Advancing Rainfall and Land Forecasting
Initial research indicates that FengShun-CSM provides enhanced accuracy for medium-range rainfall and land surface forecasts, including soil moisture and temperature. These improvements are particularly valuable for agriculture, enabling farmers to make better-informed decisions on planting, irrigation, and crop selection. The model has demonstrated strength in forecasting persistent weather patterns, although researchers note that further development is needed to improve predictions of rare and extreme events such as typhoons or sudden droughts.
Supporting Disaster Risk Management
By delivering forecasts up to two months in advance, FengShun-CSM offers government agencies and local communities additional time to prepare for potential hazards, including floods, heatwaves, and other climate-related disasters. Early warnings can be critical for organizing evacuations, pre-positioning relief supplies, and minimizing the impact on lives and property. In 2024, China experienced significant financial losses from climate-related disasters, underlining the urgent need for advanced forecasting tools.
Boosting Agricultural Planning
Farmers and agricultural planners can benefit greatly from the extended forecasts provided by FengShun-CSM. Longer-range insights into rainfall patterns and soil conditions help optimize planting schedules and resource management. In a country where food production is closely tied to weather variability, more precise forecasts are seen as an important step toward improving food security and agricultural resilience.
The Role of AI in Modern Weather Forecasting
Artificial intelligence is rapidly transforming weather prediction. AI models like FengShun-CSM process massive datasets and generate forecasts much faster than traditional physical models. China is a leader in this area, with initiatives such as Huawei’s Zhiji model and the FengShun-CSM project itself. Internationally, similar efforts are underway, including Google’s GenCast. However, experts caution that AI models depend heavily on the quality and relevance of existing data, which may limit their ability to anticipate entirely new climate trends or extreme anomalies.
Current Challenges and Ongoing Development
While FengShun-CSM marks a major step forward, its developers acknowledge certain challenges. The model's reliance on past data can reduce accuracy when faced with unprecedented or rapidly changing weather patterns, especially those driven by climate change. Efforts are underway to enhance the system's performance for rare or extreme events and to integrate AI models with traditional physical simulations, as demonstrated in ongoing tests with other advanced forecasting tools.
