| 摘 要： | 通过对2008年10月12—15日海南省特大暴雨过程特征分析，表明海南“0810”特大暴雨是热带低压和冷空气相互作用的结果，特大暴雨的发生发展及减弱与偏东和偏南风急流的加强和减弱有较好的对应关系：东风急流造成海南岛东部降雨明显大于西部。副热带高压对北上热带低压的阻拦和形成的环流对降水起到了加强和维持的作用：雷达回波为典型的积层混合型降水回波；长时间的低层辐合、高空强辐散，有利于强降雨的发生和维持。

| Abstract: | Based on the characteristic analysis of torrential rain process on OCT12-15,2008 in Hainan,it shows that this process is the result of interaction between tropical depression and cold air.There is a correspondent relation between the occurrence development or weakness of torrential rain and the rapids or decrease of east and south jet,and the heavier rain in the east of Hainan is caused by the east jet.Moreover,the rain was enhanced and maintained by the prevention of subtropical high to Tropical depression towards north and the circulation.The radar echo is the typical accumulated layer mixed precipitation echo.Long time lower convergence and high altitude strong divergence are helpful for the occurrence and maintenance of heavy rainfall. |
