Abstract: A set of 100 large geomagnetic storms associated with Dst decreases of more than 100 nT, observed during the period 1986-1996, has been analyzed. These selected large geomagnetic storm events have been compiled and their various characteristics features as well as seasonal and solar cycle dependence have been analyzed. It has been found that a maximum number of large geomagnetic storms are associated with coronal mass ejections (CMEs) during the solar cycle 22. A general study of 10 severe geomagnetic storms (Dst ≤ -250 nT) and their association with associative CMEs events and interplanetary disturbances have also been discussed.
