摘　　要：利用常规观测资料、区域自动站降水资料及Fy2G卫星云图等资料,对2020年9月13日贵州一次秋暴雨过程的成因进行诊断分析,结果表明:此次暴雨过程副热带高压(以下简称副高)强盛,随着副高减弱南压,高原短波槽东移加深,弱冷空气从东北部路径入侵影响贵州,静止锋锋生加强,配合低层南压的低涡切变线产生暴雨。Using conventional observation data, regional automatic station precipitation data and Fy2G satellite cloud image, the cause of an autumn rainstorm process in Guizhou on September 13, 2020 is analyzed. The results show that the subtropical high is strong during the rainstorm process. As the subtropical high weakens to the south, the plateau short wave trough moves slightly eastward and deepens by the invasion of weak cold air from the northeast path, the stationary front frontogenesis is strengthened, rainstorm is generated by the low vortex shear line matching with the low level southward pressure.
