摘　　要：对 0 1 0 3号台风 (榴莲 )造成华南西南部特大暴雨的过程进行了高分辨数值模拟 ,在模拟结果与实况较为一致的基础上 ,利用辐散风和旋转风动能平衡方程分析低压区域内的动能收支和转换特征 。Heavy rain in southwest of South China caused by typhoon 'Durian' is simulated by MM5. Based on the excellent agreement with the observation, the area average energetic budgets and conversion over the region of typhoon is undertaken with the balance equation of kinetic energy for the divergent wind and rotational wind, to indicate the maintaining mechanism of typhoon and the characteristic of evolution of energy, as well as the relationship between the typhoon and its outside enhanced heavy rain.
