Abstract
This paper reports a statistical study on the relationship between relativistic electron events(REE), magnetic storms, and substorms. We have used magnetic storm events that occurred between 1996 and 1998, and have classified them into two groups, (i) magnetic storms with REE and (ii) magnetic storms without REE, according to whether or not the magnetic storm is accompanied by REE. Then we have examined the characteristics of substorms that occurred during the main phase of each of the magnetic storms, and compared them between the two groups of the storms. In particular, we have made some quantitative estimations on the intensities of the energetic particle injections and magnetic dipolarizations during the substorm. We find that the injection intensity ratio and the magnetic dipolaization of the storm-time substorms are bigger for substorms with REE than for those without REE.
