TLDR
In this article, a model calculation is performed by which the magnitude and form of the anticipated atmospheric wave train may be assessed, and both are found to be consistent with observations already recorded, but the question as to whether the Lorentz force or the Joule dissipation is the more important exciting agency provided by the current, is left unanswered because of present uncertainties connected with the nature of the current itself.About:

A three-dimensional model of thermosphere dynamics—I. Heat input and eigenfunctions
Hans Volland,Hans G. Mayr +1 more
TL;DR: In this article, a three-dimensional model of the thermosphere dynamics is developed in terms of the eigenfunctions of the atmospheric system, and a three dimensional model for the external heat inputs like solar XUV-radiation and corpuscular heating during geomagnetic storms is derived.

Multiradar observations of medium‐scale acoustic gravity waves using the Super Dual Auroral Radar Network
W. A. Bristow,R. A. Greenwald +1 more
TL;DR: In this paper, observations of medium-scale acoustic gravity waves in the thermosphere, using multiple HF radars, are presented along with statistics of gravity wave occurrence, showing that during quiet intervals gravity wave phase fronts may extend longitudinally for more than 3400 km and during more active interval, the level of wave activity is elevated to the point that it is difficult to distinguish individual wave packets.

Studies of medium scale travelling ionospheric disturbances using TIGER SuperDARN radar sea echo observations
TL;DR: In this paper, seasonal and diurnal variations in the direction of propagation of medium-scale travelling ionospheric distur- bances (MSTIDs) have been investigated by analyzing sea echo returns detected by the TIGER SuperDARN radar in Tasmania.

A review of F region dynamics
TL;DR: The photochemical processes responsible for the formation of the F region of the ionosphere were identified from radio wave reflection and rocket experiments prior to 1960 as mentioned in this paper, but it was not until the decade between 1960 and 1970 that two important processes for setting the plasma in motion horizontally, namely, thermospheric winds and magnetospheric convection, were recognized and confirmed by observation.

Internal atmospheric gravity waves at ionospheric heights
TL;DR: In this paper, the proper interpretation of irregular motions in the upper atmosphere has been investigated by a variety of techniques, but their proper interpretation has yet to be established. But their proper meaning has not yet been established.

A model of the auroral electrojets
TL;DR: In this paper, a model of an arc is presented in which the height variation of the auroral ionization is taken into account and vertical currents are allowed to flow in the arc, and the electric field or wind velocity field required to drive the currents is computed for two different cases: in one, the current flow between the ionosphere and the outer magnetosphere is assumed to be limited and electric fields occur along the magnetic field lines in the magnetosphere; in the other, the conductivity along the field lines is assumed that are perfect.

Ionospheric irregularities produced by internal atmospheric gravity waves
TL;DR: In this article, a perturbation treatment is used to determine the nature and magnitude of the effects of internal atmospheric gravity waves on the ambient rates of production, chemical loss, and motion of the ionization.

HF Doppler studies of traveling ionospheric disturbances
TL;DR: In this article, a network of CW Doppler sounders was used to detect ionospheric motions observed with a network-of-CW Dopplers. The motions of each type are attributed to various kinds of atmospheric waves that interact with the ionosphere.

Propagation of acoustic-gravity waves in the atmosphere
Frank Press,David G. Harkrider +1 more
TL;DR: In this paper, the authors used homogeneous wave guide theory to derive dispersion curves, vertical pressure distributions, and synthetic barograms for atmospheric waves, and found that the major features on barograms are due to dispersion; superposition of several modes is needed to explain observed features.
