Paper Abstract

In this work, the relation of substorm activity (AE, Kp) with the solar wind electric field during the magnetic storm induced by the CIR and ICME events is investigated. The analysis of average values of AE (АЕaver) and Kp (Kpaver) indices during the main phase of magnetic storm depending on the SW electric field has shown that for the CIR events, unlike the ICME events, the value of AEaver increases with the growth of average value of the electric field (Eswaver). The value of Kpaver correlates with the Eswaver only for the ICME events. When comparing time intervals during a recovery phase of two magnetic storms during which the values of solar wind electric fields are approximately equal to each other, it is found that AE index is more in that storm in which the solar wind velocity is higher.
