层结流体中具有纬向基本剪切流的Rossby波振幅的mKdV方程

In this paper mKdV equations for the amplitude of solitary Rossby waves in stratified fluids with a zonal shear flow are derived by using weakly nonlinear method. It is found that coefficients of mKdV equations not only depend on $\beta$ effect and the Brunt frequency, but also on the basic shear flow.
