A Relaxation Model of Plasma Formations During High-Altitude Discharges
RESUMO
The intense plasma perturbations in the middle atmosphere, produced by the high altitude discharges and appearing as luminescent columns ("red sprites") are considered. A model of the perturbations of the kind relaxing in the mesosphere after termination of the luminescent phase has been developed. Analysis solutions for the nonstationary continuity equations for electrons, positive and negative ions in the plasma columns have been obtained. It is shown that ion density perturbations should be taken into account in the analysis of VLF wave reflection from the plasma formations. The ion density perturbations also can increase the life time of "sprite" -like formations in the middle atmosphere.
