Simulation of Large-Scale Disturbances of the Near-Earth Plasma Affected by High-Power High-Frequency Radio Waves from the Sura Heating Facility

We present the results of simulation of large-scale disturbances of the near-Earth plasma modified by high-power HF radio waves from the Sura heating facility. The numerical simulation was performed over the entire range of ionospheric altitudes, using an SAMI2 modified version for the input parameters corresponding to the in-situ measurements of the spatial structure of the disturbed region performed by the method of low-orbit radio tomography. The numerical simulation results conform to the radio tomography reconstruction data. The dynamics of the evolution and relaxation of large-scale temperature and plasma-density disturbances under the action of high-power HF radio waves from the Sura heater are studied on the basis of simulation data.
