Abstract: By using the routine meteorological data and NECP 1° × 1° reanalysis data，we carried out contrastive analysis of the physical quantity of two rainstorm weather processes on July 1 and 15 in 2013 in Fuxin. The results showed that the edge of subtropical high southerly airflow provided good vapor conditions．Low-level convergence and high-level divergence field configuration enhanced the pumping effect of the atmosphere and led to strong vertical ascending motion over the heavy rain area. Precipitation occurred in the corresponding zone of local maximum rising speed, not the lower rising speed zone. The storm had a good corresponding relationship with the surface layer of water vapor flux distribution and the vertical felicity in Fuxin, zone of greater value of Potential Pseudo-equivalent Temperature was also prone to rainstorms.
