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:

Nathaniel Frissell,J. B. H. Baker,J. M. Ruohoniemi,Andrew J. Gerrard,Ethan S. Miller,J. P. Marini,M. L. West,William A. Bristow +7 more
TL;DR: In this paper, a climatology of daytime midlatitude medium-scale traveling ionospheric disturbances (MSTIDs) observed by the Blackstone Super Dual Auroral Radar Network (SuperDARN) radar is presented.
Journal ArticleDOI
The role of gravity waves in tropospheric processes
TL;DR: In this paper, the role of gravity waves in the troposphere is briefly discussed and reviewed, and the physical processes involved in the interaction of gravity wave with mesoscale and planetary boundary layer phenomena are discussed.

Coupling of ionosphere and troposphere during the occurrence of isolated tornadoes on November 20, 1973
R. J. Hung,T. Phan,R. E. Smith +2 more
TL;DR: In this paper, the authors examined the coupling between the ionosphere and the troposphere during time periods with isolated tornadoes on the stormy day of November 20, 1973 and showed that the sources of the gravity waves associated with tornadoes are always on the squall lines and near the tornado touchdown locations.

The equatorial electrojet as a source of long period travelling ionospheric disturbances
TL;DR: In this article, the authors investigated the shape and strength of low frequency TID's which may be launched through the Lorentz coupling of the electrojet to the neutral atmosphere, and concluded that such coupling is very much weaker in the equatorial region than is the case at auroral latitudes.

TL;DR: A new technique is presented, based on the analysis of oblique Digisonde-to-Digisonde (D2D) “skymap” observations, to directly identify TIDs and specify the TID wave parametersbased on the measurement of angle- of-arrival, Doppler frequency, and time-of-flight of ionospherically reflected high-frequency (HF) radio pulses.

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.
