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:

Atmospheric gravity wave production for the total eclipse of 11 June 1983.
TL;DR: The internal atmospheric gravity bow waves generated by the eclipse of 11 June 1983 will focus over central Australia as discussed by the authors, and the bow waves will be generated by a large-scale solar eclipse.

Meteorology of the upper atmosphere
TL;DR: The four-year period of the early 1970s saw very active work on many aspects of upper atmosphere meteorology: energetics, imposition, thermal structure, and wind systems as mentioned in this paper.

Global large scale structures in the F region
TL;DR: In this paper, the authors show that at times of low magnetic activity, quasi-stationary waves excited by the auroral belts are distributed about the Earth possibly with tidal or sub-tidal periods and scale lengths determined by the structure of the belts.
A morphological study of waves in the thermosphere
TL;DR: In this article, the ionosphere, gravity waves in the thermosphere, and large scale waves observed by AE satellites are discharged, and the effects of these waves are investigated.

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.
