The results showed that erectness of coupling pattern between upper-layer jet and low jet and a divergence area, which came forth in right of upper-layer jet provide favorable surrounding conditions. The most intensive moisture convergence, the strongest ascending movement and the most instable convection stratification all occurred in the rainfall center. The rainstorm occurred at the warm and wet side of the negative value center of the moist potential vorticity and relative MPV, which had certain indicative significance for the forecast of rainstorm areas.
