| 摘 要： | 用1958到1989年共32年资料对东亚及西太平洋地区的锋面气旋做了统计研究,气旋生成有两个主要的集中区,蒙古生成区次数最多,沿海生成区次之并还可以分为两个分区。各生成区中心位置和中心数值随季节有不同的变化。 气旋中心气压24小时变化值呈负偏态分布,海洋地区气旋的负偏度更大,爆发性气旋主要出现在海洋上,沿海地区也时有发生。有明显年际、月际变化,主要发生在冬季,次为春季.文中还对爆发性气旋各种特征参数做了详细统计。 用计算气旋活动的相对变率方法,定出了四季气旋主要活动路径。

| Abstract: | A statistic study of frontal cyclones over East Asia and north-western Pacific for the period 1958-1989 is carried out by using the historical weather maps compiled b.y State Meteorological Centre. There are two major cyclo-genesis areas including the Mongol cyclogenesis area, in which the great frequency occurred, and the East Asia coastal cyclogenesis area. All of those areas appeared a pronounce seasonal variation.The seasonal variation of explosive cyclones are also discussed. Finally, the main cyclone tracks are determined by the relative variation of cyclones. |
