This research is intended to communicate the results of inter-relationship that exist among the following interplanetary
magnetic field (IMF) parameters: (Bz, By, Bt) and the geomagnetic index (GI): (Ap, Kp, Dst, Ae) along side with the
plasma parameters (T, P and V) during geomagnetic storm. The relationship between the field parameters, GI and plasma
parameters with disturbance storm time index (Dst) was studied. A correlative study between the geomagnetic indices
and the peak values of various plasma and field parameters during the geomagnetic storm of April 2010 were also
presented. Our study shows that, while some of the parameters play active role in Dst morphology, some do not. An
antiphase relation was observed in total field and Dst index. Hence mechanisms of the interplay between the parameters
are also discussed.
Keywords: Geomagnetic storm and Disturbance storm time index, Dst.
