Abstract: The dependence of the geomagnetic field variations during a great magnetic storm on the initial state of the magnetosphere-ionosphere system is investigated. It is shown that intensity of auroral electrojet is controlled by integral wind parameters for several hours. The sensitivity of the magnetosphere-ionosphere system to changes of the solar wind parameters increases with the enhancement of ionosphere disturbance. The greater is the initial level of the ionosphere disturbance, the greater is the amplitude of the following variations at the same changes of interplanetary medium parameters.
