Geoeffectiveness Of Cir And Cme Events: Factors Contributing To Their Differences, L Laughlin, Niescja E. Turner

Physics and Astronomy Faculty Research

Recent work has shown that solar wind-magnetosphere coupling is more efficient for CIR-driven events than for CME-driven events. The study herein looks into the individual physical parameters of Corotating Interaction Regions (CIRs) and Coronal Mass Ejections (CMEs) and looks to isolate particular characteristics that leads to greater coupling of energy from the solar wind into the magnetosphere for certain classes of magnetic storms. While it is clear that these two types of events are distinct in their outcome, it is not known what in the nature of the events leads to these different results. The variation level in the z-component …
