Abstract: In the report, the wind profile radar was used for the vertical measurement of the tropical precipitation cloud, which can classify it clearly. With the statistics characteristics of precipitation cloud in Haikou（2017）, a classification scheme of tropical precipitation cloud based on wind profile radar observation（echo intensity, velocity and spectral width） was created. With the classification scheme and various observations, two precipitation processes in 2017 were analyzed. The results showed that the data from wind profile radar can observe the vertical structure of precipitation cloud and describe the variation trend of precipitation cloud more accurately than that from weather radar. Compared with the traditional precipitation classification scheme, the classification scheme of tropical precipitation cloud based on wind profile radar can improve the classification accuracy of complicated precipitation weather system. Wind profile radar can describe the rapid transit weak convection system in high-altitude.
