摘　　要：利用常规气象观测资料、区域自动站资料、多普勒天气雷达资料、欧洲中心数值预报资料,对2020年7月9日发生在南平市中北部的一次强降水天气过程进行分析。此次强降水是前倾槽、静止锋、高层辐散低层辐合、高层冷平流低层暖平流等动力和热力条件共同作用的结果,多种有利条件在闽北地区叠加,使得此次对流性降水进一步增强,造成了此次降水量级大、强度强、维持久。This paper uses conventional meteorological observation data,regional automatic station data,doppler weather radar data,and european center numerical forecast data to analyze a heavy precipitation weather process that occurred in the central and northern part of Nanping City on July 9,2020.This heavy rainfall is the result of the combined effect of dynamic and thermal conditions such as forward-dipping troughs,stationary fronts,high-level divergence and low-level convergence,high-level cold advection and low-level warm advection.The superposition of multiple favorable conditions in northern Fujian further enhanced the convective precipitation,resulting in a large,strong,and durable precipitation.
