Abstract：Based on Zhaoqing X-band dual polarization weather radar data and rainfall data of automatic weather station,this paper analyzes the multiple precipitation processes in 2019.Firstly,the data are selected and processed,and the quality of the data is controlled by filter and attenuation correction.Then,the difference of precipitation estimation between different models is compared and analyzed.Finally,the precipitation process of a case is analyzed.The results show that reasonable quality control is needed to improve the accuracy of precipitation estimation.It is of great significance to improve the calculation method of KDP for precipitation estimation by radar.
