The goal of this study is to see how high-power, high-frequency radio waves pushed into the ionosphere at high latitudes affect ionospheric plasma characteristics. The ground-based ionospheric heater at Tromso, Scandinavia, is used to calculate three-dimensional distributions of ionospheric parameters using a mathematical model of the high-latitude ionosphere developed earlier at the Polar Geophysical Institute. The model accounts for ionospheric plasma flow, significant plasma magnetization at F-layer altitudes, and geomagnetic field declination. The computations were done for two different scenarios. First, we modelled ionospheric parameter distributions under normal conditions without a strong high-frequency wave influence. Second, the ionospheric parameter distributions were estimated on the assumption that the ionospheric heater had been turned on, and that the ionospheric heater was located on the night side of the Earth. The numerical simulation results show that artificial ionosphere heating by powerful high-frequency waves should have a significant impact on the spatial structure of the nocturnal high-latitude F-region ionosphere in the vicinity of the ionospheric heater.
