TLDR
In this article, the authors analyzed the auroral zone electric field data obtained by the flight of 32 balloons between L = 5.4 and L = 8.2 and concluded that important parallel potential drops exist along auroral magnetic field lines or simple conjugacy between the two hemispheres does not exist along such field lines.Abstract:
Four hundred and seventy-eight hours of electric field data obtained by the flight of 32 balloons between L = 5.4 and L = 8.2 have been averaged to determine mean properties of the auroral zone electric field. The results are understood in terms of a model in which the two-cell convection pattern is rotated about the sun-earth line by an amount that depends on the sign and magnitude of the y component of the interplanetary magnetic field. This model and the data suggest either that important parallel potential drops exist along auroral zone magnetic field lines or that simple conjugacy between the two hemispheres does not exist along such field lines.read more

A quantitative model for the potential resulting from reconnection with an arbitrary interplanetary magnetic field
Walter D. Gonzalez,F. S. Mozer +1 more
TL;DR: In this article, a quantitative model for the electric potential arising from magnetopause reconnection is proposed, in which several approximations are made concerning configuration of the magnetosheath flow, limitations on the magnitude of the reconnection speed, and the geometry of the problem.

Auroral arc thicknesses as predicted by various theories
TL;DR: In this article, the authors examined 12 electron acceleration mechanisms and 10 generator mechanisms for auroral arcs, and a characteristic auroral-arc thickness was worked out for each mechanism except one, and the arc thicknesses were then mapped down to the ionosphere along the terrestrial magnetic field lines; near the Earth, a dipole magnetic field model was used, and farther from the Earth the mapping included the effects of magnetic field-line draping.

Theory of the low-latitude boundary layer
TL;DR: In this paper, a steady state fluid mechanical model is developed of the low-latitude plasma boundary layer inside the dawn and dusk magnetopause, which is achieved via field-aligned currents, the magnitude of which is limited by parallel potential drops.

TL;DR: In this article, it was found that a model with a southward interplanetary magnetic field leads to a natural explanation of the SD currents and speculative aspects of the problem as they appear at this time are discussed.

Instability, Turbulence, and Conductivity in Current-Carrying Plasma
TL;DR: In this article, the mechanism of this phenomenon is explored mathematically, and it is shown that collective Coulomb interactions (i.e., small-angle collisions) cause instabilities which grow so rapidly that relative motion of ions and electrons are continually damped down by conversion of directed energy into random fluctuation energy.
