Paper Abstract

The paper presents the results of 2D numerical simulations with a magnetohydrodynamic model "shallow water" which was used to estimate the influence of magnetic field on increments of instabilities in the tachocline caused by anomalies of the mean flow. Calculations confirmed the previously obtained result about the strong influence of anomalies of the mean flow on the instabilities of the differential rotation. Average magnetic field of relatively small magnitude stabilized development instabilities, but when it reaches a critical value, stabilization stopped and typical time of instabilities development sharply decreased. Also instabilities significantly well depended on amplitudes of initial perturbation velocity field and the magnetic field.
