| 摘 要： | 为了分析热带海气耦合系统中不稳定扰动究竟由哪种自由波占主导地位，根据本文第I部分提出的热带海气耦合模式，讨论了取耦合系统中不同的径向模时耦合波的性质，即分别讨论了大气长Rossby波和海洋长Rossby波、大气Kelvin波和海洋长Rossby波、大气长Rossby波和海洋Kelvin波的耦合波以及考虑了大气和海洋中所有这些波动时耦合波的性质。结果指出，这些耦合波对海气耦合模式中参数的取值很敏感，不同的参数可以产生性质不同的耦合波。本文的结果也说明了海气耦合系统的性质与热带大气的性质和结构有很大关系。

| Abstract: | In order to find which free waves in the air and sea are dominative in the unstable disturbanc(ofthe air-sea coupled system, the properties of coupled waves for different meridional modes in Lheair-sea couPled system are discussed, respectively, based on the tropical air--sea interaction model roposed in Part I of this paper. Through studies of the coupled waves of atmospheric Rossby wave' vs.oceanic ones, atmospheric Kelvin wave vs. oceanic Rossby waves, atmospheric Rossby waves vs oce nicRossby waves, and the coupled waves in the case when all these waves in the air and sea are conside ed,respectively, the results show that all these coupled waves are sensitive to the parameters used in themodel and different properties can be obtained with different parameters. The results also indicate beatthe characteristics of the air-sea coupled system have much to do with the property and structure of theatmosphere. |
