friction let off

In order to simulate the equatorial current system characerized by the North Equatorial Current, the South Equatorial Current, the Equatorial Counter-current and the Equatorial Undercurrent, the time-averaged linearized motion equations are used as the governing equations, and the seawater stratification and longitudinal friction are taken into consideration.

为了模拟以南、北赤道流、赤道逆流和赤道潜流为特征的赤道流系,从长时间平均的线性化的海水运动方程出发,考虑海水层化、保留经向摩擦作用,利用赤道太平洋中部海区经向流通量不随纬度变化的量阶估计,得到海水密度跃层对赤道风场的响应,即跃层深度的分布规律,然后应用我们已构建的改进 Fourier方法求解(由于地转β效应所引入的)变系数的海水运动方程,得到适用于中部赤道太平洋的级数形式的三维流场解。
