海南岛中低纬冷暖系统相互作用下的非台暴雨分析

Analysis of the Non-tropical Cyclone Rainstorm in the Condition of Reciprocity between the Middle Latitude Cold Air and the Low Latitude Warm Low in Hainan Island

通过对1993年～2002年共10年的天气资料分析发现,在海南,中纬度的冷空气与低纬度在南海上活动的低压之间的相互作用,是秋季产生非台暴雨的非常重要的环流形势;同时发现,低空急流的存在与暴雨的产生有密切联系。并且对2000年10月13日～15日的暴雨过程利用T106物理量场诊断分析,说明暴雨形成的原因。

The analysis of the weather information of ten years from 1993 to 2002, find out that it's the very important circulation pattern for the generation of non-tropical cyclone rainstorm in autumn in Hainan island that the reciprocity between the middle latitude cold air and the low latitude warm low in South China Sea . Also discover that it's tie up between the low-level jet and the rainstorm. In addition, analysis of the rainstorm process of 2000/10/13-2000/10/15 using physical quantity fields, find out the causes for rainstorm.
