利用NCEP再分析资料、FY-2E卫星资料和常规观测资料等，采用天气学分析、物理量诊断等方法，对1312号台风“潭美”空心结构特征及成因以及其造成的暴雨天气过程进行了初步分析。结果表明，台风“潭美”深对流云系一块位于台风中心北侧，一块位于南侧，且后期北侧减弱，几乎完全偏向台风的南侧，台风中心周围仅有浅薄稀疏的低云云线。“潭美”动力、热力结构均存在明显空心和不对称性特征，其与中高层气旋性环流偏离、高层辐散不对称、水汽输送不对称等有关；强降水分布与台风不对称性结构及地形等有关。WRF中尺度模式能较好地模拟出不对称性结构以及降水强度和分布。

With the observation data, NCEP reanalysis data and FY-2E satellite data, a study is made to discuss the reasons why the tropical cyclone“TRAMI”has hollow and asymmetric structure. The conclusions are as follows:The dynamic and thermodynamic structures of “TRAMI” are obviously asymmetric, which are associated with the cyclonic circulation deviation at mid-level, the asymmetric divergence at high-level and the asymmetric transportation of the water vapor. The asymmetric heavy rainfall distribution is related to the asymmetric structure and the terrain. WRF model is able to simulate the asymmetric structure of the “TRAMI”, the corresponding precipitation intensity and distribution.
