Galerkin method; nonlinear problem; two-dimensional oceanic circulation
Summary: This note points out the main numerical results concerning a nonlinear problem of two-dimensional oceanic circulation. Using a peculiar eigenfunction basis, the nonlinear terms can be treated in a particular suitable way such that the time needed by a finite difference method for solving the problem is reduced in a large part.
