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

WebWithin about an hour the nightside neutral line begins to return a sufficient amount of flux to the dayside, and convection approaches equilibrium. Magnetic reconnection drives magnetospheric convection much more efficiently than does viscous interaction. Consequently, all phenomena associated with convection are much enhanced over … WebDec 16, 2005 · [1] During periods of steady enhanced magnetospheric driving, it may be possible for the reconnection rate on the nightside to adjust to match the reconnection … Webthat sudden reductions in the convection electric field (northward turnings of the IMF) and dynamic pressure pulses can trigger substorm onset (Hsu and McPherron, 2002).
