TLDR
In this paper, an artificially created ion cloud is assumed to have a relative velocity with respect to the ambient plasma originating from the momentum of the satellite from which the cloud is released and because of the convection of the magnetospheric plasma itself.About:

Magnetosphere-ionosphere coupling
C. K. Goertz,R. W Boswell +1 more
TL;DR: In this article, a simple two-dimensional model of the magnetosphere-ionosphere system is discussed in which a localized electromotive force applied across a magnetic field line at t = 0 is shown to propagate along the magnetic field with the Alfven velocity.

TL;DR: A comprehensive review of dispersive Alfven waves in space and laboratory plasmas is presented in this article, where the authors show how the inclusion of ion gyroradius, parallel electron inertia, and finite frequency effects modify the Alfven wave properties.
Journal ArticleDOI
Feedback instability of the ionospheric resonant cavity
TL;DR: In this paper, a model is developed that provides a theoretical basis for previous numerical results showing a feedback instability with frequencies characteristic of Alfven travel times within the region of the large increase of the Alfven speed above the ionosphere.
Journal ArticleDOI
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.

Dynamics of magnetosphere-ionosphere coupling including turbulent transport
Robert L. Lysak,Christian T. Dum +1 more
TL;DR: In this paper, the dynamics of magnetosphere-ionosphere coupling were investigated by means of a two-dimensional two-fluid MHD model including anomalous resistivity, and the system evolved toward an electrostatic structure, with the perpendicular electric field having a shorter scale than the field-aligned current.

Formation of plasmapause, or magnetospheric plasma knee, by the combined action of magnetospheric convection and plasma escape from the tail
TL;DR: In this article, the magnetic lines of force in the magnetosphere are separated into two groups: those that travel across the tail during the convective motion and those that are never transported to the tail.
Journal ArticleDOI
Bulk motion of the magnetosphere
TL;DR: In this article, an upper atmosphere geophysical measurements are surveyed to determine to what extent the available data support the concept of bulk motion of the magnetosphere (convection) and the associated electric field.

A theory of electrostatic fields in a horizontally stratified ionosphere subject to a vertical magnetic field
TL;DR: In this paper, small-scale electrostatic fields are studied with a view towards elucidating the phenomena of spread F and radio star scintillation, and the results are strongly affected by the variation of conductivity with height, as well as by the anisotropy.
