1960—2013年影响渤海的热带气旋特征分析

Statistical Analysis of Tropical Cyclones which Affected the Bohai Sea during 1960—2013

文章利用上海台风研究所热带气旋年鉴资料,对1960—2013年发生在西北太平洋上的热带气旋路径进行逐一分析,筛选出其中可能对渤海造成灾害的个例并进行分类;根据路径特点及影响强弱将其分为四大类,简要阐述各类特点并分析不同类型所对应的天气形势,为渤海防灾减灾工作及进一步深入研究提供依据。经过统计分析得出:1960—2013年(共54年)共有88个热带气旋可能影响渤海,平均每年为1.63个;每年的7—9月为主要影响期,占全年93.2%。

By using the tropical cyclone data from Shanghai Typhoon Research Institute from 1960 to 2013,this paper analyzed the tropical cyclones which occurred on Northwestern Pacific Ocean and selected the ones which might affect the Bohai Sea.The tropical cyclones were classified into 4types according to the characteristic of their routes and the related weather situations were analyzed,which was very helpful in defeating the tropical cyclone disasters and doing further research.The results indicated that there were 88 tropical cyclones which affected the Bohai Sea in the past 54 years,averaged 1.63 per year.Most tropical cyclones occurred in July,August and September,which took up 93.2%in the whole years.
