ECOLOGICALLY SAFE REGIMES OF GENERATION AND MAINTENANCE OF ARTIFICIALIONIZED REGIONS IN THE STRATOSPHERE BY MICROWAVE-RADIATION

A mathematical model of the artificial ionized region created in the a tmosphere in the intersection zone of two beams of powerful coherent T E microwaves is presented. The model is based on the solution of the n onstationary system of Maxwell equations and kinetic Boltzmann equatio n for electrons, as well as on a vast ramified kinetic scheme of plasm a chemical processes in humid air. In the framework of such a model, i t is possible to calculate, in a correct and self-consistent way, the electrodynamic and kinetic characteristics of the artificial ionized r egions (AIR) created in air at various altitudes. The calculations con ducted for the stratosphere had revealed the possibility of realizatio n at great altitudes (similar to 55 km) of the regimes of the AIR prol onged maintenance that simultaneously have the following advantages: t hey require the minimum energy expenditures, ensure good radio-reflect ing properties of the plasma structure and do not lead even to local d egradation of the ozone layer. Modeling of the kinetic and photochemic al processes proceeding at the postdischarge stage had shown that the destructive action of the NOx molecules produced in the discharge on t he stratospheric ozone is substantially limited by their diffusive tra nsport beyond the AIR boundaries. Production of excess active hydrogen radicals HOx in the discharge does not exert any essential influence on ozone due to fast proceeding of the reactions of their mutual bindi ng.
