TLDR
In this article, the angular velocity of the upper atmosphere is determined by examining the changes in orbital inclination of all suitable satellites, covering the years 1958-63, height of 200-300 km and latitudes from 0-60°.About:

Whistler studies of the plasmapause in the magnetosphere: 1. Temporal variations in the position of the knee and some evidence on plasma motions near the knee
TL;DR: The position of the knee in the density of magnetospheric ionization was measured on a high time-resolution basis using whistlers recorded during July and part of August 1963 as discussed by the authors.

Polarization fields produced by winds in the equatorial F-region
TL;DR: In this article, the E-layer conductivity may be too small to close this circuit, so that polarization fields build up in the F-layer, causing the plasma to drift with the wind.

Atmospheric winds between 100 and 700 km and their effects on the ionosphere
TL;DR: In this article, the global atmospheric wind system produced at different local times by pressure gradients in the upper atmosphere is calculated using data from Jacchia's model atmosphere, and it is suggested that these may readily explain many anomalous ionospheric observations including the midday bite-out, some features of the maintenance of the night-time ionosphere, and the universal time effects observed in the high-latitude ionosphere.

Thermospheric winds and the F-region: A review
TL;DR: In this paper, the effects of the neutral-air winds on the ionospheric F2-layer are considered in some detail, starting from a discussion of the forces acting on the air, the equations of motion are set up and solved.
Journal ArticleDOI
Electrical coupling of the E- and F-regions and its effect on F-region drifts and winds
TL;DR: In this paper, the effects of the electric field distribution on the geomagnetic field lines linking the E-and F-regions were investigated by solving the electrical and dynamical equations.

The upper atmosphere in motion
TL;DR: In this article, a review of the observational evidence for the upper atmosphere is presented, in groupings determined by the physical processes that are thought to be operative, and corresponding theories are measured against it.

Luni-Solar Perturbations of the Orbit of an Earth Satellite
TL;DR: In this article, the effects of the gravitational attraction of the Sun and Moon on the orbital elements of an Earth satellite were investigated using Lagrange's planetary equations, and expressions for the change in the elements during one revolution of the satellite and for the rates of change of these elements were obtained.

Horizontal Movements in the Ionosphere
B H Briggs,M Spencer +1 more
TL;DR: In this paper, a survey of the existing knowledge of horizontal movements in the ionosphere as obtained by radio methods is presented, and the results obtained at Cambridge, England, by this method are compared with other workers using this and other methods in different parts of the world.
