In view of three rainstorm processes (“6·19”,“7·5” and “7·19” processes) during Meiyu period in Hubei Province in 2016, firstly, the sounding data of Hankou station were compared with the horizontal wind speed and wind direction from Hankou and Xianning wind profile radar stations. It was found that the horizontal wind speed below 3 km from Hankou wind profile radar station was close to sounding data in the “6·19” and “7·5” processes; the horizontal wind direction and wind speed below 8 km from Xianning wind profile radar station were basically consistent with the sounding data in the three processes. Combined with the data of conventional and encrypted automatic weather stations, the horizontal wind field, average vertical velocity and its variability, vertical shear of horizontal wind speed and atmospheric refractive index structure constant $C_{n}^{2}$ were analyzed by using wind profile radar. The results are as follows: (1) The southwest wind speed increased significantly before the beginning of precipitation. The invasion of dry and cold air in the middle layer and the mesoscale easterly air flow formed by the ground cold pool were the main reasons for the occurrence of strong winds with more than and equal to 17.2 m·s^-1 at 50 stations in the “6·19” process, and the long-term maintenance of the southwest jet and the easterly air flow below 1 km in the “7·5” and “7·19” processes were the inducements for the long duration of short-term heavy precipitation. (2) The vertical shear of horizontal wind speed, the variation of average vertical velocity and its variability with height observed by wind profile radar were small, and strong upward movement was mainly concentrated below 4 km height. (3) Before the occurrence of heavy precipitation, the atmospheric water vapor content had an increasing process, and the water vapor content in the whole layer was deep. The disappearance of the large value area of $C_{n}^{2}$ corresponded to the end of precipitation.
