Cyclone Monitoring

( Back to Cyclone Warning Services )

A constant watch is kept on the Arabian Sea and the Bay of Bengal for the likely genesis of tropical cyclones with the help of satellite imagery, particularly those from the Indian geostationary satellite, INSAT. Data from ships and ocean buoys is also very valuable. When the systems come nearer to the Indian coastline, their subsequent development and movement is monitored by a chain of Cyclone Detection Radars set up by IMD to cover the entire coastal belt. The likely movement of the storms is predicted with the help of track prediction models and by reference to past climatology which has been built up using 125 years of cyclone data.
