HF Doppler studies of traveling ionospheric disturbances

Journal of Atmospheric and Terrestrial Physics, 1968
Abstract Wavelike ionospheric motions observed with a network of CW Doppler sounders are analyzed and found to fall into four separate classes not previously distinguished. The motions of each type are attributed to various kinds of atmospheric waves that interact with the ionosphere.

Analysis of large-scale traveling ionospheric disturbances

Journal of Geophysical Research, 1964
It is shown that an acoustic-gravity wave interpretation of Chan and Villard's observations of large-scale traveling ionospheric disturbances is consistent with theory. By using the dispersion curves and kinetic energy profiles for atmospheric gravity waves recently computed by Pfeffer and Zarichny, Pfeffer and Gersten, and earlier by Press and ...

A theory of medium-scale traveling ionospheric disturbances

Journal of Geophysical Research, 1974
Analysis of the excitation of atmospheric gravity waves leads to a hypothesis concerning the nature of medium-scale traveling ionospheric disturbances (TID's) and their relation to large-scale TID's. Stationary phase techniques are used to derive the asymptotic fluctuations of velocity and electron density generated by a line source (e.g., the auroral ...

Travelling Disturbances in the Ionosphere: Diurnal Variation of Direction

Nature, 1953
THE detection of travelling disturbances in the F-region of the ionosphere has already been reported1. In the last-mentioned paper, it was stated (p. 221): “It has not yet been possible with the limited data available to detect any definite diurnal variation”.

Occurrence of Giant Travelling Ionospheric Disturbances at Night

Nature, 1959
A RECENT publication1 from this laboratory has discussed the existence of large travelling ionospheric disturbances which during winter daylight hours travel from south to north over the east coast of Australia. This type of disturbance first described by Munro and Heisler2 has been tracked from Hobart to Townsville, a distance of 3,000 km.
