| 摘 要： | 按不同地段统计分析了1884—1980年期间东亚登陆台风个数以偏多期与偏少期交替为特征的长期振动。发现东亚沿太平洋的多数地段上登陆台风数的长周期振动的主要周期为20年左右,较短周期的振动主要有5～6年和2～3年周期。不同地段上长期振动的差异主要表现在周期、位相和振幅上。还发现登陆台风数的长期振动与春夏季节关键地区的大型气压环流的低频振动有某种关联。

| Abstract: | In this paper, the long-term fluctuations of the landing typhoon which are characterised as the inversion of more/less periods are statistically analyzed in terms of various coastal regions in the East Asia during 1884-1980.The fluctuation periods of most coastal regions are about 20-yr (low frequency)and 5-6-yr(high frequency). The differences among the long-term fluctuations over various coastal regions are shown with period, phase and swing.Some relationship between the long-term fluctuations of the landing typhoon and low frequency fluctuations of large-scale pressure circulation are illustrated finally. |
