Dependence of normal modes of the barotropic vortex equation on the mean flow structure and numerical simulation parameters

Solar-Terrestrial Physics
We present the results of numerical simulations of normal modes of the mean flow due to the superposition of cyclonic and anticyclonic vortices at high latitudes.
