| 摘 要： | 本文利用历史天气图资料,对1973—1988年中国东部和沿海地区的温带气旋及其爆发性发展情况进行了统计,共有1014个温带气旋发生,其中有1/5达到了爆发性发展的强度,构成了西太平洋爆发性海洋气旋的一部分.它占整个西太平洋爆发性气旋总频数(包括不同来源)的51％.进而对这类爆发性气旋的活动规律进行了分析,概括出了它们的气候学特征.比较亚洲大陆、中国近海及西太平洋地区的爆发性温带气旋表明,西太平洋地区不仅频繁而且强烈.而东、西太平洋地区发生海洋爆发性气旋的对比表明,二者存在着明显的差异.同时也指出,东太平洋地区爆发性气旋的发生并不是一种少见的现象.

| Abstract: | During 1973- 1988 periods, there were 1014 extratropical disturbances over East China and off seaboard. One-fifth of them developed into explosive cyclones over the West Pacific. The ratio of this kind of explosive cyclones to all ones over the West Pacific (including various types) accounts for 50%.The comparsion of explosive cyclones indicates that the explosive cyclones over the West Pacific were about twenty times as much as that over the continent Asia and the East Asian coastal area. 84.6% cf explosive cyclones over the continent of Asia ar< weaker, while most of the explosive cyclones over the East China Sea and the West Pacific are moderate or strong.Power spectrum analysis of explosive cyclogenesis frequency shows that 6-month and 4-month periods prevailed. |
