ABSTRACT:
The large-scale disturbance of the spatial structure of the daytime
high-latitude F-region ionosphere, caused by powerful high-frequency radio waves,
pumped into the ionosphere by a groundbased ionospheric heater, is studied with
the help of the numerical simulation. The mathematical model of the
high-latitude ionosphere, developed earlier in the Polar Geophysical Institute,
is utilized. The mathematical model takes into account the drift of the
ionospheric plasma, strong magnetization of the plasma at F-layer altitudes,
geomagnetic field declination, and effect of powerful high-frequency radio
waves. The distributions of the ionospheric parameters were calculated on
condition that an ionospheric heater, situated at the point with geographic
coordinates of the HF heating facility near Tromso, Scandinavia, has been
operated, with the ionospheric heater being located on the day side of the Earth.
The results of the numerical simulation indicate that artificial heating of the
ionosphere by powerful high-frequency waves ought to influence noticeably on
the spatial structure of the daytime high-latitude F-region ionosphere in the
vicinity of the ionospheric heater.
