Deflected magnetosheath flow at the high-latitude magnetopause

This paper presents results of a study that uses the output of a global MHD simulation to investigate the geometry and dynamics of solar wind deflecti on from tangential magnetic force acting at the magnetopause. Tangential ma gnetic force at the magnetopause is a consequence of merging between the ge omagnetic field and the interplanetary magnetic field at the dayside magnet opause, This is the first study explicitly to show deflection of magnetoshe ath flow at the magnetopause and to compute deflection phenomenon quantitat ively using self-consistent MHD. The presentation connects magnetopause def lection with polarcap magnetic perturbations called the Svalgaard-Mansurov effect.
