Variable Coefficient KdV Equation for Amplitude of Nonlinear Solitary Rossby Waves in a Sort of Time-Dependent Zonal Flow
Variable Coefficient KdV Equation for Amplitudeof Nonlinear Solitary Rossby Waves in a Sortof Time-Dependent Zonal Flow

On the basis of the quasi-geostrophic vorticity equation, theoretical research has been down upon the evolution of the amplitude of solitary Rossby waves employing the perturbation method, and come to the conclusion that the evolution of the amplitude satisfies the variable coefficient Korteweg-de Vries (KdV) equation.
