A numerical study of polar ionospheric currents

Planetary and Space Science, 1973
Numerical calculations for the electric current in the polar ionosphere have been made by assuming some realistic distributions of the electric field and conductivity. Two dynamo actions are taken into account; one of which is induced by ionospheric winds and the other by the solar wind.

Residual ionization in the polar lower ionosphere

Journal of Geophysical Research, 1962
S>Turbulent scattering of 2.3 Mc/s radio waves is found to persist throughout the polar night between altitudes of 80 and 100 km at a geomagnetic latitude of 79 deg S. Residual electron densities are estimated to increase from 5/cm/sup 2/ at 80 km to 1 or 2 x 10/sup 2/ between 90 and 100 km.

Polar, Magnetic, Auroral, and Ionospheric Phenomena

Reviews of Modern Physics, 1960
storms which appear to arise from atmospheric sources, though their ultimate causes may be situated beyond the atmosphere. The intense electric currents flowing in the auroral regions are described with related spacial features of the polar and low latitude fields measurable by polar orbiting earth satellites. The earth as a mirror machine is described,

Interactions Between the Polar Ionosphere and Thermosphere

Physica Scripta, 1987
The temperature, composition and circulation of the ionosphere and thermosphere in the polar regions are closely coupled and display a marked variation with altitude, latitude, longitude, universal time, season, solar cycle, and geomagnetic activity. To a large degree, this variation is a consequence of the effect that magnetospheric electric fields ...
