Features of steady magnetospheric convection

WebJul 7, 2024 · 1. Introduction. The existence of a minimum of the equatorial northward magnetic field component, B z, in the Earth's magnetotail has been suggested theoretically as a feature of steady adiabatic convection (e.g., Hau, 1991).Such a minimum forms as plasma sheet convection proceeds and the magnetic field of the inner tail becomes … WebAlthough it is still an open question whether the magnetospheric source of the ionospheric convection electric field is best described by a constant current or a constant voltage generator, we have chosen in this study to treat the field-aligned current as the driving term for several reasons. Since the field-aligned current (as
