FlowCast: Advancing Precipitation Nowcasting with Conditional Flow Matching

ArXi:2511.09731v4 Announce Type: replace Radar-based precipitation nowcasting, the task of forecasting short-term precipitation fields from previous radar images, is a critical problem for flood risk management and decision-making. While deep learning has substantially advanced this field, two challenges remain fundamental: the uncertainty of atmospheric dynamics and the efficient modeling of high-dimensional data.
