摘    要:通过对1949—2009年61年间登陆和影响浙江的热带气旋的时空分布特征、主要影响路径等的分析,发现在7—9月份登陆浙江的热带气旋占登陆总数的92.5%,7—9月份影响浙江的热带气旋占影响总数的82%。影响浙江的热带气旋中登陆福建或在台湾海峡消失的热带气旋占的比重最多。虽然西北太平洋上热带气旋生成个数近年来大幅减少,但登陆浙江的强台风有明显增多的趋势。随着气候的变暖,海水温度的增高,热带气旋生成的时间提早,结束的时间偏迟。另外通过对热带气旋影响时各海岛、沿海和内陆站的大风、暴雨的分析,发现热带气旋影响期间容易引起大风天气的是大陈和嵊山站;容易引起暴雨天气的是温岭、临海和温州站。本文还分析了验潮站最大增水超过1m、2m、3m的时空分布特征。

关 键 词:浙江  热带气旋  时空分布  增水

Abstract:In this paper,detailed analysis is made on the moving trajectory and the temporal-spatial characteris-tics of the tropical cyclones(TCs) landing in Zhejiang province during 1949—2009.The historical data show that 92.5% of the TCs in total landing in Zhejiang province occur from July to September,whereas 82% of the TCs have impact on Zhejiang province.The TCs impacted Zhejing mostly made landfall in Fujian province or died away in the Taiwan Strait.Although TCs formed over the western North Pacific decreased in recent years,the number of strong typhoons(STY) which made landfall in Zhejing province has increased.With the impact of global warming and sea water temperature increasing,the TCs are likely to generate earlier and end later More-over,the gust speed and rainfall amount are analyzed at several island,coastal and inland stations during typhoon season.The results show that strong wind tend to occur at Dachen and Shenshan stations,while storm rain tend to occur at Wenling,Linhai and Wenzhou stations.The temporal-spatial characteristics of the storm surge(with a maximus surge over 1m,2m and 3m) are also analyzed during typhoon season at tide gauge stations
Keywords:Zhejiang province  tropical cyclones  temporal-spatial characteristics  storm surge
