【Abstract】 The multiple equilibria and their catastrophe of the low-order barotropic model are studied. With the change of the external thermal forcing parameters, the variations in the equilibrium character or the stability properties may occur in the nonlinear low-order barotropic system under the action of topographical forcing, resulting in the catastrophe between high-index and low-index.更多还原
