| description | The invention provides a thunderstorm identification and threat assessment method based on speed assistance. The method comprises the following steps: step 1, obtaining stereo meteorological echo data of a plurality of pitching sectors from a t0 moment; step 2, carrying out reflectivity and movement speed deviation calculation on the meteorological echo data of the plurality of pitching sectors; 3, performing target discrimination on the reflectivity by using a meteorological radar thunderstorm identification method so as to obtain characteristic parameters of a plurality of concerned targets; step 4, carrying out thunderstorm identification on the plurality of concerned targets, and obtaining a plurality of identified thunderstorms; and 5, carrying out mass center offset calculation and mass center movement speed calculation on the plurality of identified thunderstorms to judge thunderstorm threat degrees. According to the invention, by emitting a group of coherent electromagnetic wave pulses, the raindrop m |
