Role of Remote Sensing and GIS in Cyclone

Dhruvesh KM, Praful MU and Aditya MV

Due to long Indian coastal line of 7517 Km India is more vulnerable to coastal flood, soil erosion, tropical cyclone, Tsunami. In India every year five or six tropical cyclones are form in Bay of Bengal and strike the east coast of India. Out of this two or three cyclones could be severe and more hazardous to human life. Cyclones occur frequently on both the coasts (The west coast Arabian Sea; and the east coast Bay of Bengal). More cyclones occur in the Bay of Bengal than in the Arabian Sea and the ratio is approximately 4: 1.In India, Tropical cyclones occur in the months of May-June and October- November. The cyclones of severe intensity and frequency in the north Indian Ocean are bimodal in character, with their primary peak in November and secondary peak in May. The disaster potential is particularly high at the time of landfall in the north Indian Ocean (Bay of Bengal and the Arabian Sea) due to the accompanying destructive wind, storm surges and torrential rainfall. Of these, storm surges are the greatest killers of a cyclone, by which sea water inundates low lying areas of coastal regions and causes heavy floods, erodes beaches and embankments, destroys vegetation and reduces soil fertility. In this research paper we are discussing formation of cyclones and its parameters. How GIS and remote sensing is beneficial before and after cyclone to reduce causalities and damage of life and property.
