影响青岛的热带气旋特征分析

Characteristic analysis of The tropical cyclones influenced Qingdao

本文对1949～2007年共59年影响青岛的热带气旋统计特征进行了分析。结果表明,影响青岛的热带气旋移动路径主要有5种类型,其生成源地与移动路径有一定的关系。影响时间主要集中在7月下旬至9月上旬;各月影响的主要路径及平均强度不同,影响时青岛出现6～7级的风力及偏北、南南东的风向频率较高,沿岸有时会伴有强的风暴潮。

The Statistical characteristic of tropical cyclones which influenced Qingdao in fitly-nine years from 1949 - 2007 is analysed in this paper. The result shows that there are five types of tropical cyclones＇ moving paths which have influences on Qingdao, these moving paths are related to the source regions of the tropical cyclones. The time that the tropical cyclones influenced Qingdao is mainly in the last decade of July and the first decade of September. The main paths and available intensity of the influence are different. when the tropical cyclones influenced Qingdao, the wind-scale of 6- 7 and the wind direction efficiency of north or south-southeast are main, at the same time, there are strong storm tides alongshore sometimes.
