Wind aloft inversion method based on Doppler weather radar data

The method provides a wind aloft inversion method based on Doppler weather radar data. The method utilizes extrapolation products and radial velocity products of the Doppler weather radar, and air sounding data to carry out a multi-level wind aloft field fusion. The invention utilizes an extrapolation result of a radar echo image to convert an average radial velocity field of each elevation planeinto a velocity vector field with U and V components, thereby improving the readability of a subjective analysis of the wind aloft field. The invention utilizes the air sounding data to appropriatelycorrect a radar wind field, and the strength of the correction decreases with the increase of the distance between a radar grid point and a sounding station, so that the wind field has better integrity and continuity, and is more accord with the condition of an actual atmospheric wind field. Compared with some multi-data fusion methods, the algorithm of the method provided by the invention has moderate computational comple
