作者在文献[1]中曾简单地导出过一个描述大洋风生一热盐环流的“风旋度—热盐梯度方程式”,它是一个全流函数所满足的线性位涡方程,表达了海面上风应力旋度和界面上的热盐梯度在侧向湍摩擦所导致的涡度扩散下与行星涡度梯度的平衡。利用该方程,在一个矩形大洋中,作者提出了一个相当简单的准两层模型,并用以描述了大洋风 In [1], the author simply derived a “wind curl-heat salt gradient equation” describing the ocean wind-heat salt circulation, which is a linear potential-vorticity equation satisfied by a full-flow function and expresses the sea surface Windward curl and thermal gradient at the interface are balanced by planetary vorticity gradients due to vorticity diffusion caused by lateral turbulent friction. Using this equation, in a rectangular ocean, the authors propose a rather simple quasi-two-layer model that describes the oceanic wind
