Using the data of incoherent scattering (Institute of the Ionosphere, Kharkov), the response of the ionosphere to magnetic storms of different intensity was investigated. It is established that the amplitude of the response is complexly related to the intensity of the storm. The most likely reason for such behavior of the ionosphere is the state of the thermosphere before the start of the disturbance. The role of tidal and planetary waves is also considered.
