Tropical cyclones (TCs) are well known for their devastation, mainly due to torrential rains, strong winds and associated storm surges, which cause flooding, soil erosion and landslides, even far away from the landfall location, resulting in numerous human casualties and enormous property damage. These disasters are particularly severe over the North Indian Ocean (NIO), comprising both the Bay of Bengal (BoB) and Arabian Sea (AS), as their coastal areas are heavily populated. In the past 300 years, out of all recorded cases of very heavy loss of life (ranging from about 5000 to well over 300,000) in the world due to TCs, more than 75% cases have occurred in the BoB and AS (WMO Technical Report, 2008).
