通过对连续层化条件下赤道海洋波动及相关环流特征尺度和物理量的尺度分析 ,全面分析了赤道海洋波动及其相关环流所属动力学系统的性质。分析结果表明 ,该系统为以参数 ε为表征的弱非线性动力学系统 ,在此基础上建立了适合描述赤道波非线性效应的动力学模型。 By analyzing the scale and physical characteristics of the equatorial oceanic fluctuations and related circulation features under continuous stratification, the properties of the equatorial oceanic fluctuations and their related dynamical systems are thoroughly analyzed. The analysis results show that this system is a weakly nonlinear dynamic system characterized by the parameter ε, on the basis of which a dynamic model suitable for describing the nonlinear effect of the equatorial wave is established.
