Study of Energy Injection during Intense and Super Intense Geomagnetic Storm Driven by Coronal Mass Ejection (CME)
Abstract
We have studied the energy injection process associated with CME driven storms that occurred during 18th February 1998, 4th May 1998, 16th July 2000 and 20th November 2003. The energy injection efficiency was parameterized by the ԑ parameter as a measure of the energy transfer of solar wind into the magnetosphere; we observed that intensification of ring current (Dst) depends on the energy injection into the magnetosphere and the duration of a particular CME event. In the same vein, we discovered that large geomagnetic storm was more associated with large time difference (Tdiff.) between the peak of storm and peak of energy injection.
