Problems solved by technology

Due to the limitation of the measurement mechanism of this method itself, the measured wind speed is relative to the wind speed in the direction of the line connecting the measurement point and the radar, and the measured wind direction is the direction away from or towards the radar on the line, that is to say, The measured wind direction and speed is the wind speed projection of the real wind direction and speed of the measurement point on the line connecting the measurement point and the radar center. This wind speed projection is only a component of the real wind direction and wind speed, that is, the radial wind, and cannot represent the real wind direction and speed of the measurement point.
The radar measurement data often cause forecasters to misunderstand the wind distribution in the air, resulting in a decline in the applicability of the measurement data
[0003] At present, many meteorological radars in China have been networked, and the data has been shared. However, the measurement of the distribution of wind direction and speed in the air is still in the measurement of radial wind, not the real wind direction and speed.

technical field [0001] The invention relates to the technical field of radar wind measurement, in particular to a wind speed and wind direction inversion method, device, equipment and storage medium. Background technique [0002] At present, the measurement of wind direction and speed distribution in the air by weather radar is mainly based on the Doppler effect. Due to the limitation of the measurement mechanism of this method itself, the measured wind speed is relative to the wind speed in the direction of the line connecting the measurement point and the radar, and the measured wind direction is the direction away from or towards the radar on the line, that is to say, The measured wind direction and speed is the wind speed projection of the real wind direction and speed of the measurement point on the line connecting the measurement point and the radar center. This wind speed projection is only a component of the real wind direction and speed, that is, the radial wind, an...
