Abstract
We study the temporal evolution and time lag characteristics of interplanetary coronal mass ejection (ICME) induced geomagnetic storm (GS) by comparing the geomagnetic storm time evolution with the time variation of four selected solar wind plasma and interplanetary magnetic field parameters, (B, V, Bz, Ey). We selected 25 events over the Solar Cycle 24 as well as we identified their characteristics during their near-Earth passage. To analyze, we evaluate the time lag of previous parameters for 25 different intensities geomagnetic storms (GS) using (Dst/SYM-H) index which have time resolutions respectively (1 hour, 1 minute). We apply a correlation analysis of the time lag of GSs with specific features of ICMEs. We apply an exponential fit to the recovery profile for the GS events associated with ICME for hourly data between the Dst index and selected interplanetary plasma and interplanetary magnetic field parameters. These findings provide useful insight of the geomagnetic storm evolution and solar-terrestrial connection.
