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:

Gravity waves in the upper atmosphere of Venus
TL;DR: In this article, the transfer function model of Mayr et al. was modified to describe gravity waves in the thermosphere of Venus in terms of spherical and Fourier harmonics.
Journal ArticleDOI
The synthesis of travelling ionospheric disturbance (TID) signatures in HF radar observations using ray tracing
TL;DR: In this article, the F-region skip distance was found to be a function of the peak electron density perturbation associated with the traveling ionospheric disturbances (TIDs) and radar frequency.

Large-Scale Waves in the Thermosphere Observed by the AE-C Satellite
TL;DR: In this paper, the authors analyzed the data from the Atmosphere Explorer C (AE-C) during one orbit on January 20, 1975, and showed that strong periodicities are apparent that persist throughout the records, regardless of filter cutoff frequency.

The bow wave generated by an auroral arc in supersonic motion
G. Chimonas,W. R. Peltier +1 more
TL;DR: The mechanism through which infrasound is generated by the supersonic translation of auroral electrojet currents is investigated quantitatively in this article, where it is shown that the pressure pulse received at the ground can give a quantitative description of the currents flowing along the arc.
Journal ArticleDOI
Propagation of internal acoustic‐gravity waves around a spherical Earth
TL;DR: In this article, the authors investigated the refraction of internal acoustic-gravity waves by the earth's spherically symmetric gravitational field by using the approximation of geometrical acoustics in an isothermal atmosphere.

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.
Journal ArticleDOI
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.
