Fig. 12

Magnetosphere-ionosphere-ground current circuit achieved in a steady state. The east–west symmetry leads to the zero-potential in the noon-midnight meridian, which can be replaced with the perfectly conducting sheets (dashed lines). Downward and upward currents of the same amount are supposed to connect the ionospheric currents to the ground surface currents in the duskside and dawnside current circuits driven by the positive and negative potentials, respectively.
