| 摘 要： | 将两层约化重力原始流体动力方程耦合气候月平均风场，数值计算流场基本能够正确反映热带太平洋上层主流系和温跃层的空间分布和季节变化．在气候平均条件下，东太平洋125°W附近经向风应力可激发出高阶混合Rossby重力波．海洋高阶赤道Kelvin波流速模态可从西太平洋边界传播到东太平洋边界，而高阶赤道Kelvin波温跃层模态从西太平洋边界东传后，在中太平洋受到高阶混合Rossby重力波诱发的西传温跃层扰动的阻挡．

| Abstract: | The current field was calculated on the basis of the coupling model of a two-layer, reduced gravity primitive equation and the climatic average wind field. The result correctly shows space distribution and season variety of the main current system and thermocline of upper layer in the tropical Pacific. The mixed Rossby-gravity waves were excited by meridional wind stress on 125°W equatorial Pacific. In the climatic condition, the equatorial Kelvin wave current model could be transported from the western equatorial Pacific border to the eastern border, but the equatorial Kelvin wave thermocline model was not, because it was prevented by the westward thermocline perturbation which was excited by mixed Rossby-gravity in the central equatorial Pacific. |
