Researchers have developed a novel two-stage framework using a U-Net architecture to improve extreme precipitation forecasting. This method combines probability classification with value reconstruction, blending forecasts from six major numerical weather prediction (NWP) models. A key innovation is the joint supervision mechanism that integrates observations from over 2,400 meteorological stations in China, simultaneously refining spatial structures and peak intensities. Evaluations show significant improvements over individual NWPs and existing products, particularly for heavy rainfall events, transforming forecasts from having negligible utility to possessing operational value.
