中文摘要: |
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. |
英文摘要: |
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 by State Meteorological Centre.There are two major cyclogenesis areas including the Mongol cyclogenesis area, in which the great frequbacy occurred, and the East Asia coastal cyclogenesis area.All of those areas appeared a pronounce seasonal variation.The seasonal variation.The seasonal variation of explosive cyclones are also discussed.Finally, the main cyclone tracks are determined by the relative variation of cyclones. |
