摘　　要：利用MMSV3中尺度数值预报模式对2004年5月18-19日造成云南暴雨过程的孟湾风暴进行了数值模拟，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，分析盂湾风暴的能量收支和转换特征，揭示孟加拉湾风暴维持的机制及其与外围暴雨增幅的关系。The Bengal storm occurred during the 18th and 19^th of May 2004 is simulated by a mesoscale numerical model MM5V3. Based on the excellent agreement with the observation the area-average energetic budgets and the conversion over the storm region is undertaken with the balance equation of the kinetic energy for the divergent wind and rotational wind. The maintaining mechanism of the Bengal storm, the characteristic of the energy evolution and the relationship between the Bengal storm and its outside enhanced heavy rain is indicated.
