A STUDY OF TROPICAL CISK-ROSSBY WAVE'S DYNAMIC CHARACTERS AND THE MECHANISM OF 30～50 DAYS OSCILLATION

摘要: 基于斜压准地转模式的动力学分析,讨论了CISK-Rossby波产生、传播的动力机理和不同的波结构及热力强迫对热带大气30～50天振荡传播的制约和影响,解释了30～50天振荡的一些重要传播特性,特别是对30～50天振荡的经向传播机理和垂直“斜压”结构等问题作了较为细致的探讨,提出了一些新的见解和观点。

Abstract: Based on the dynamical method of baroclinic quasi-geostrophic mode,the dynamic mechanisms of CISK-Rossby's generating/propagating and the influence/restriction on 30～50 days oscillation exerted by CISK-Rossby wave's different structures and thermal forcing are discussed, some important propagation characteristics of 30～50 days oscillation are explained, especially,some questions such as the meridional propagation mechanism and the vertical 'baroclinic' structure etc of 30～50 days oscillation are carefully explored,some new opinions and viewpoints are presented.
