Abstract

In this paper, we examine the relationship of the SME index with magnetic storm characteristics and inter-planetary medium parameters during the main phase of magnetic storms caused by CIR and ICME events. Over the period 1990– 2017, 107 magnetic storms driven by (64) CIR and (43) ICME events have been selected. Close correlation coefficients between SME_aver and the SW electric field have been obtained for CIR and ICME events. SME_aver has been found to increase with the rate of magnetic storm development and |Dst_min|.
