The Modulation Instability of Nonlinear Rossby Waves in the Weakly Dissipative Atmosphere
弱耗散作用下非线性Rossby波的调制不稳定

In this paper, the WKB method is applied to investigating nonlinear Rossby waves with weakly shear zonal flow and weak dissipation in the atmosphere, and a nonlinear Schrodinger equation with complex coefficients for nonlinear Rossby waves is obtained. On the other hand, the side - band stability problems of Rossby wavetrains with no dissipation and weak dissipation are discussed, respectively, and some new results are derived.
