利用多年的ECMWF高分辨率再分析资料，基于影响降水的大尺度环流系统区分华南锋面和季风两类降水，对比分析华南锋面和季风两类降水的中尺度环境特征，揭示两类降水对流系统的典型中尺度特征差异；利用再分析资料、TRMM测雨卫星雷达（PR）和微波成像仪（TMI）资料以及探空资料反演的加热廓线，从观测资料揭示不同降水对流系统垂直加热廓线的特征及差异并给出目前模式模拟加热廓线的水平，归纳总结出锋面和季风两类不同降水对流系统典型的垂直加热廓线。通过中尺度模式对两类不同类型降水对流系统环境特征和加热廓线模拟效果的评估，揭示目前中尺度模式对两类降水模拟可能存在的问题.

Using the multi-year data of ECMWF high-reserlution reanalysis data, the frontal and monsoonal convective systems in Southern China are identifided based on the influence of large-scale circulation on precipitation.Comparing the meso-scale environmental characteristics between frontal and Monsoonal convective systems, the differences of typical meso-scale environmental characteristics between them are revealed. Based on the inverted heating profiles from reanalysis data, TRMM PR and TMI as well as sounding data, heating characteristics and their differences of frontal and monsoonal convective systems are exposed and the e differences of heating profiles from the observation and current model are shown. Throung the evluation of meso-scale numerical model on the simulated results of envionmental characteristics and heating profiles from different precipitation convective systems, the possible problems of meso-scale numerical model simulating both precipitation systems are revealed.
