A TEST FOR THE DIFFERENCE SCHEME OF A GENERAL CIRCULATION MODEL

In this paper, we test our difference scheme of a GCM by using two methods. First, we adopt the conventional Rossby-Haurwitz wave as the initial conditions to test the simplified barotropic model. The results are as good as that obtained by the barotropic model of ECMRWF. Second, we developed a nonlinear Haurwitz wave for the baroclinic primitive equations, then use it to test our GCM. The results of the tests are very encouraging.
