摘要
根据1961-2005年有编号的热带气旋资料,从时间和空间两个方面统计分析了影响中国东海附近海区（117°-131°E,22°-33°N）的热带气旋特征。结果表明,统计区域内的影响热带气旋具有明显的年际变化特征,年平均频数为8.6个,年频数与厄尔尼诺具有很好的相关性,厄尔尼诺年为影响热带气旋少频年;影响热带气旋主要集中在6-10月,持续时间多在1-4天之间;影响热带气旋大多生成于菲律宾以东洋面和关岛附近洋面,从统计区域的南侧和东侧进入,主要有西北、东北和转向3条移动路径。
The statistical characteristics of Tropical Cyclones（TCs） affecting the East China Sea（117°E to 131°E,22°N to 33°N） are analyzed by means of the TC data from 1961 to 2005.The results indicate that there is obvious annual variation in TCs over East China Sea with 8.6 TCs per year averagely;the numbers of TCs have good correlation with El Nino phenomenon,during which the numbers of TCs are less;TCs appear mostly from June to September,and the durations of TCs are usually less than 5 days;TCs form mostly in the Pacific area east of Philippines and the sea area around Guam,mostly come from south or east with three moving paths： northwest,northeast,and direction-turning.
