Magnetosheath's parameters and their dependence on intensity and direction of the solar wind magnetic field

Abstract

The variations of the plasma parameters and of the magnetic field in the vicinity of the stream line passing the subsolar point at the magnetopause are calculated by using a special flow pattern of the plasma which is the result of the formation of a stagnation line at the nose part of the magnetopause. The calculations indicate a rotation of the direction of the magnetic field across the magnetosheath. The displacement of the magnetopause due to the penetration of the solar wind magnetic field into the magnetosphere is discussed.
