In the context of a system of barotropic shallow-water equations and Boussinesq approximate equations for two-dimensional meso-scale transversal wave disturbance in zonally sheared base flow, study is performed of the physical process of the meso disturbance propagation along the flow, indicating that such vortex Rossby waves are separated into two kinds. The first kind VRW is produced owing to the second-order horizontal shear in the flow or due to the meridional change in vertical vorticity of the flow, i.
