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:

High-frequency radar observations of atmospheric gravity waves in the high-latitude ionosphere
TL;DR: The Johns Hopkins University high-frequency coherent scatter radar at Goose Bay, Labrador, observed the effects of propagating atmospheric gravity waves, particularly in ground backscatter returns as mentioned in this paper.
Journal ArticleDOI
Dynamic effects of aurora-generated gravity waves on the mid-latitude ionosphere
TL;DR: In this article, a brief review of aurora-generated large-scale traveling ionospheric disturbances is given, and results of numerical simulations of one such event are presented. But the results of simulations are limited to the case of the 18 September 1974 event.

Adrian Grocott,Keisuke Hosokawa,T. Ishida,Mark Lester,Steve Milan,Mervyn P. Freeman,Natsuo Sato,Akira Sessai Yukimatu +7 more
TL;DR: In this article, a survey of medium-scale traveling ionospheric disturbances (MSTIDs) observed by a Super Dual Auroral Radar Network HF radar located in the Falkland Islands between May 2010 and April 2011 is presented.
Journal ArticleDOI
Climatology of short-period mesospheric gravity waves over Halley, Antarctica (76°S, 27°W)
TL;DR: The wave headings exhibited unusually strong anisotropy with a dominant preference for motion towards the Antarctic continent and a rotation from westward during fall, to poleward in mid-winter, to eastward in spring.
Journal ArticleDOI
A modelling study of the coupled ionospheric and thermospheric response to an enhanced high-latitude electric field event
TL;DR: In this paper, the effect of a short-lived, localized enhancement in the high-latitude dawnside convection electric field has been made using the Sheffield/UCL/SEL (Boulder) coupled ionosphere/ thermosphere model.

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.
Journal ArticleDOI
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.
