Abstract: In order to compensate the disadvantages of traditional verification methods,the heavy precipitation process in Sichuan on June 22,2019 was tested with MODE (Method for Object Based Diagnostic Evaluation) of object matching technology. Through the determination of the parameters of the method,it can be found that:(1)The determination of MODE convolution radius R and precipitation threshold value T,should be selected by considering MODE resolution and weather event scale flexibly.(2)In view of this process,SWC-warms is well grasped to the development and extinction of precipitation,especially for the northeast of the basin that the target shape,trend,movement direction and fall area has a good correlation; However,it has obvious false reports in the early stage of precipitation development.(3)For intensity prediction, the plateau target intensity prediction field has certain overestimation in the area of large precipitation value,and the basin target intensity prediction is basically close to the real situation during the period of strong precipitation development,but the basin target intensity prediction also has obvious overestimation when the precipitation weakens.
