Probabilistic Precipitation Nowcasting with Rectified Flow Transformers

ArXi:2605.31204v1 Announce Type: new Accurate weather forecasts are essential across various domains and are safety-critical in extreme weather conditions. Compared to simulation-based forecasting, data-driven approaches show greater efficiency, enabling short-term, high-resolution nowcasting. In particular, diffusion models proved effective in weather nowcasting due to their strong probabilistic foundation.
