Study of the Large-scale Modification of the Ionosphere Induced by High Frequency Radio Waves with Different Powers: A Simulation Approach | Chapter 5 | Research Trends and Challenges in Physical Science Vol. 2

 The goal of this study is to see if intense high-frequency radio waves, used for artificial heating experiments and pushed into the ionosphere by ground-based ionospheric heaters, may cause large-scale ionosphere change. The mathematical modelling method is used in this inquiry. The Polar Geophysical Institute produced a mathematical model of the ionospheric E and F regions. For fall circumstances, simulations are run for the site with geographic coordinates of the "Sura" heating station (Nizhny Novgorod, Russia). The calculations are carried out for a variety of scenarios in which the effective absorbed power varies between 5 and 100 MW, including both nocturnal and daylight situations. The frequency of intense HF waves is chosen to be close to the most effective frequency for F2-layer alteration on a broad scale. The findings of the modelling show that the effective absorbed power has a significant impact on the F-layer response to high-power radio waves in the ionosphere at mid-latitudes.
