- Institute of Cosmophysical Research and Radio Wave Propagation FEB RAS
In this work, according to the ground observation data, we study the dynamics of the ionospheric parameters during periods of strong and moderate magnetic storm of 2015–2017. The study was carried out using new methods of modeling and data analysis proposed by the authors. Multicomponent model of ionospheric parameters presented in this work allows describing changes of the ionospheric parameters, both in the conditions of the calm ionosphere and in perturbed periods. During the study, we allocated ionospheric disturbances preceding and accompanying the periods of magnetic storms in analyzing regions. The analysis showed a high incidence of the effect of an increase in the electron concentration of the ionosphere preceding the onset of magnetic storms. Comparing the results of the study with cosmic ray data, we also noticed the correlation of effects in the ionosphere with the anomalous changes in the dynamics of cosmic rays.
