MHD-modelling of the magnetosheath ion plasma flow and magnetic field and their comparison with experiments

A problem of the solar wind flow around the magnetopause is rather complex but a combination of the numerical modeling and experimental observations can bring a progress in magnetosheath studies. In this contribution, we have used the MHD BATS-R-US model for prediction of magnetosheath ion flux and magnetic field profiles under specific upstream conditions. The comparison is based on two INTERBALL-1 passes through the magnetosheath at low and high latitudes. We discuss the influence of the Earth’s dipole tilt, the IMF direction, and latitude dependence on profiles in both MHD simulations and experimental investigations.
