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:

The role of acoustic gravity waves in the generation of spread-F and ionospheric scintillation
TL;DR: In the aggregate, acoustic gravity waves in the F-region constitute a spectrum of geophysical noise extending from the frequencies involved in diurnal variations up to the Brunt-Vaisala buoyancy frequency.

Response of the thermospheric density to auroral heating during geomagnetic disturbances.
H. Volland,Hans G. Mayr +1 more
TL;DR: In this article, the authors simulate the atmospheric density response to auroral heating during geomagnetic disturbances simulation assuming impulse heat input into small latitude band within the auroral ovals.

Energy deposition in the thermosphere caused by the solar wind
TL;DR: In this article, the authors reviewed the subject of joule dissipation of ionospheric currents and movement of the thermosphere by electric fields and compared the depositions of energy into the upper atmosphere by charged particles and electric fields.

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.
Journal ArticleDOI
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.
