Abstract. The nonlinear system of equations for Rossby-Khantadze waves in a weakly ionospheric plasma by incooperating sheared zonal flow is given. It is shown that in the presence of multiple-scale analysis, our obtained set of equations can be decomposed into one- dimensional equation which we call nonlinear modified KdV (MKdV) equation illustrating the propagation of solitary Rossby-Khantadze waves.

Short summary
It is shown that sheared Rossby-Khantadze waves can propagate due to inhomogeneities taking into account in Earth's angular velocity and in magnetic field. Along with the Hall conductivity, these waves can couple in ionospheric E region.The novelty of the present work is the consideration of magnetic field inhomogeneity which is not considered before and reduced our considered system of equation into 1D modified KdV equation.
