Physics of natural and HF - induced ionospheric disturbances and their effects on radio communication
Abstract
We report a theoretical study of ionospheric disturbances caused by either natural or man-made processes. Thirteen papers published in either technical journals or conference proceedings are compiled in this report, These papers discuss: (1) the identification of the sources of free energy, the optimum conditions for plasma instabilities as the courses of naturally occurring ionospheric irregularities, and (2) the nonlinear effects leading to the HF ionospheric disturbances such as lower hybrid waves, upper hybrid waves, ionospheric irregularities, and geomagnetic field fluctuations.
