An Ionospheric Model for Currents,the Electric Field,and the Plasma Density in an Auroral Arc.

摘要

A model of an auroral arc is presented for the self consistent calculations of currents,the ionospheric electric field,and the plasma density. The results of model calculations are presented for a selection of assumed values of the magnetospheric electric field and an anomalous resistance to geomagnetic field-aligned currents. These calculated currents and electric fields are shown to be in qualitative agreement with the published measurements. (Author)
