| 摘 要： | 本文对一种海－气耦合非线性模型运用稳定性分析、拟能函数和Ｍｅｌｉｎｉｋｏｖ函数进行了理论分析，讨论了该系统的振荡、分岔和非周期性态。结果表明，当系统拟能最小时，具有有界的稳定周期解；系统拟能最大时，将出现分岔。考虑交叉因子作用时，系统有３个平衡态。考虑阻尼作用后，通过Ｍｅｌｉｎｉｋｏｖ函数导出的系统出现分岔的参数方程说明，系统存在唯一的不稳定极限环。

| Abstract: | A nonlinear coupled stochastic model of the Sea air interaction is set up By using enstrophy function and Melnikov function, the phenomena of the vibration, bifurcation and chaos of a sea air climatic system were discussed The probality relation of these states and climatic variation is studied With increasing of CO 2, air sea system states is maybe caused |
