热带气旋对宁波降雨分布的影响分析

摘要

分析了1949～2008年间120个对宁波市造成影响热带气旋的年内分布情况,及其移动路径、强度变化对宁波市降雨分布的影响.结果表明:热带气旋的不同行进路径、不同登陆地点以及不同影响时间,直接影响宁波市降雨的时空分布及降雨的强度,分析的结果可以作为今后防台工作中相似预报的参考.%This paper studied the changes of spatial and temporal distribution of rainfall in Ningbo City when different-type tropical cyclones arrived, identified the placement of storm center and analyzed the frequency of the placement to find out the impacts of different tracks on the placement.This paper also analyzed the relationship between different tracks of tropical cyclone and the average surface rainfall process in Ningbo City, and revealed their inherent laws so as to provide useful help and guidance for the prevention of tropical cyclone in the future.
