Tropical Cyclone activities over the North Indian Ocean (comprising Bay of Bengal and Arabian Sea) constitute one of the major natural disasters of our country. To understand the Tropical Cyclonic activities, estimations of their frequencies are necessary. In this study, number of Geomagnetic Storms (Sudden and Gradual type) during 22nd and 23rd solar cycle and Cyclonic disturbance that includes Depression, Cyclonic Storm and Severe Cyclonic Storm over the North Indian Ocean has been analysed using Spearman Rank Correlation technique. Geomagnetic Storms increase the Cyclonic Activity over the North Indian Ocean.
