On an average, 2 to 3 cyclones make landfall in India each year, with at least one on them being a severe tropical cyclone. About Cyclone Biparjoy Originated as a depression on 6 June, it developed as an extremely Severe Cyclonic Storm; Cyclone Biparjoy originated in the Arabian Sea and in India, it landed in Gujarat and parts of Rajasthan; What are the requirements for cyclones to foster? 1. water temperature must be above 27 degrees Celsius, 2. unstable conditions in the atmosphere such as thunderstorms 3. a pre existing disturbance 4. a very low vertical wind shear 5. at least 5*c latitude distance from equator (cyclones do not form at the equator since there is no Coriolis force at the equator); What is the cyclonic vulnerability of India? India's vast coastline of roughly 7500 kilometers, opening to Bay of Bengal and Arabian Sea makes India very vulnerable to tropical cyclones; Both Arabian Sea and Bay of Bengal are potent breeding grounds for cyclones as they have warm oceanic water The funnel like shape of Bay-of-Bengal intensifies cyclones and points it towards India; Also, with the rise in global warming, it is likely that the area would be fountainhead of many more severe cyclones Which agency deals cyclone monitoring in India? The Indian Meteorological Department (IMD), it functions under Ministry of Earth Sciences IMD is the principal agency responsible for meteorological observations, weather forecasting and seismology. The IMD has a categorization for tropical cyclones as per various intensities these are : Depression Deep depression cyclonic storm severe cyclonic storm very severe cyclonic storm extremely severe cyclonic storm super cyclonic storm;
