Abstract: Wind profilers are used for detecting the wind distribution of the atmosphere. During precipitation, owing to the influence of the terminal velocity of raindrops, the temporal variation of the real vertical wind structure can not be obtained directly. As wind profiler and Doppler weather radar are based on the same Doppler pulse principles, through the radar meteorological equation, the vertical structure of precipitation echo intensity, the content of liquid water in clouds and the Doppler terminal velocity of raindrops can be acquired. At the same time the wind structure of the atmosphere can be obtained through correction by the Doppler terminal velocity of precipitation particales .
