Our results of electron density measurements made by the partial reflection radar in the ionospheric D region at mid-latitudes during eleven magnetic storms are presented. The response of the D region to magnetic storms at their onset and during the recovery phase is considered. Quasi-periodic increases in the D-region electron density by more than 50–100 % are revealed to last for tens of minutes with the periods T>30–60 min. The ionization rates are estimated, and the parameters of the energetic particle fluxes are calculated.
