Parametric Excitation and Suppression of Convective Plasma Instabilities in the High Latitude F-Region Ionosphere.
Abstract
Parametric coupling processes of a large amplitude electromagnetic pump wave with convective plasma fluid instabilities (E X B gradient drift and current convective) in the high latitude F region ionosphere have been studied. We find that a pump wave, with frequency near the upper hybrid frequency and with electric field, can stabilize or destabilize the E X B gradient-drift and/or current convective instability. For parameters typical of the nighttime high latitude F region ionosphere we find stabilization or destabilization with a vertically incident 0 mode carrying a free space incident power density on the order of w/10000 sq m.
