Abstract

The invention discloses a clear-air vertical wind profile detection method and system based on Doppler weather radar. The method includes: controlling the antenna beams of the weather radar to point to five wave positions of the vertical wind profile according to a preset detection cycle; Obtain the full-range power spectrum data of each of the wave positions output by the weather radar; perform non-coherent accumulation and averaging operations on each of the full-range power spectrum data to obtain five groups of average power spectrum data; The spectrum data is stored as final power spectrum data according to the wind profile radar data format; wind field inversion is performed on the final power spectrum data to obtain a vertical wind profile product. The invention realizes the detection of the clear sky vertical wind profile by using the Doppler weather radar, and expands the function of the Doppler weather radar.

Description

technical field [0001] The invention relates to the technical field of weather radar, in particular to a clear-sky vertical wind profile detection method and system based on Doppler weather radar. Background technique [0002] Weather radar is mainly used for monitoring and early warning of disastrous weather. It can quantitatively detect information such as rainfall echo intensity, radial velocity, and velocity spectrum width. Its meteorological products also have vertical wind profiles, but the meteorological products must It can only be obtained under weather conditions, and the accuracy is low. Under clear sky conditions, according to the operation mode of conventional weather radars, it is difficult to obtain vertical wind profile information. At present, under clear sky conditions, the vertical wind profile is basically obtained through special meteorological equipment such as sounding radar or wind profile radar. Additional equipment needs to be added to increase eq...
