Abstract To address the limitations of traditional numerical weather prediction models in short-term and nowcasting precipitation forecasting,this study investigates high-resolution radar data processing and feature extraction techniques.The proposed improved bio-echo extraction network,MFF-PSPnet,demonstrates superior adaptability and performance in small-sample scenarios through structural innovations.Results indicate that this fusion technique effectively improves forecast accuracy,and its application in operational meteorology can strengthen disaster early warning capabilities and decision support,holding significant implications for the future development of precipitation forecasting technologies.
