To model the wind-driven ocean circulation of the isobath rectangular basin,the linear vorticity equation with the meridional friction terra was used compared to the Munk'stheory on the ocean circulation. The generalized solution of the vorlicity equation was thus workedout in the sense of Fourier averaging by using the corrected Fourier expansion. The method to obtainthe undetermined coefficients was presented using the viscous boundary conditions.
