ENSO循环与亚、澳季风和南、北方涛动的关系

ENSO CYCLE ASSOCIATED WITH ASIAN/AUSTRALIAN MO-NSOON AND SOUTHERN/NORTHERN OSCILLATION

摘要: 文中从研究ENSO循环的成因出发,分析了厄尔尼诺(El Nino)和拉尼娜(La Nina)的产生与西太平洋暖池地区西风异常的关系;在此基础上,探讨了西太平洋西风异常的形成和变化与亚洲和澳大利亚冬季风的关系;最后,分析了亚、澳冬季风的活动,西太平洋西风异常的形成和东传,以及厄尔尼诺和拉尼娜的交替出现等现象与南方涛动和北方涛动传播波的联系。

Abstract: In this paper, in order to investigate the causes for the for mation of ENSO Cycle, we first examine the relationship of El Nino and La Nina events with the westerly wind anomalies over the western Pacific warm pool.On this basis, the roles of the Asian and Aust ralian winter monsoons in the formation and progress of the westerly windanomalies are studied.Finally, we analyze the associations of the Asian and Australian winter monsoons, the westerly wind anomalies and the El Nino and La Nina alternations with the propagating anomalies of the Southern and Northern Oscillation.
