| Abstract: | Two interacting nonlinear Rossby waves in the barotropic fluids can be described by a set of coupled nonlinear Schrodinger equations. In the previous paper the equations are solved analytically and numerically to discuss the behavior of the envelope solitary waves and their collision interactions. In the present paper the periodic wave solutions and their stability of the equations are investigated and the criteria for stability and instability are obtained. |
