Studies of Westward Electrojects and Field-Aligned Currents in teh Magnetotail during Substorms: Implications for Magnetic Field Models

摘要

Our studies elucidated the relationship between the aeroral arcs and magnetotail phenomena. One paper examined particle energization in the source region of the field-aligned currents that intensify at substorm onset when the arc brightens to form the westward electrojet. A second paper examined the relationship between the precipitating particles in the arcs, the location of the westward electrojet, and magnetospheric source regions. Two earlier papers also investigated the roles that field aligned currents and particle acceleration have during substorms.
