Ionospheric Irregularities Initiated by Planetary Waves

Cosmic Research, 2001
The nonstationary process of the accumulation of ions of meteoric origin, which is caused by propagation of planetary waves at altitudes of the lower ionosphere, is considered. Based on horizontal and vertical ion drift in planetary waves, a possibility of plasma density increases by a factor of 10–20 in comparison with the background concentration is ...

Planetary wave effect on ionospheric absorption

Journal of Atmospheric and Solar-Terrestrial Physics, 1998
Abstract A relationship is examined between quasi-periodic fluctuations in absorption data at ionospheric altitudes and wave perturbations in wind data at tropospheric, stratospheric and lower mesospheric heights at Indian latitudes. The spectral analyses using Maximum Entropy Method (MEM) reveal almost the same band of periodicities in both the ...

Observed Properties of Planetary Ionospheres

1973
Information on the ionosphere of Earth has accumulated for the past four decades. Originally, electron density was the only primary quantity observable by groundbased radio techniques. During the last two decades information on other physical parameters of the ionosphere, such as charged particle temperature (T e , T i and ion composition (m i ), as ...

Beaming of electromagnetic radiation by planetary ionospheres

Icarus, 1970
Abstract Use is made of elementary analytical and experimental results to predict an increased directivity from sources radiating inside or outside plasma layers. It is found that the directivity enhancement is higher when the source is between two plasma layers.
