Why in News
- Unusual formation due to the warming of the Bay of Bengal basin; protracted gestation could lead to its gaining strength
- Cyclonic storm Fani, which is lying about 600 km east of Vishakapatnam and 800 km south of Puri, is the first severe,
- cyclonic storm to have formed in April in India’s oceanic neighbourhood since 1976,
- according to records from the India Meteorological Department (IMD).
- While severe cyclones (defined as generating maximum windspeeds of 89-117 kmph) can form any time, they tend to be concentrated in November — after the monsoon — or around May, when the monsoon prepares to arrive in Kerala in June.
- This is a cyclone that’s forming due to the warming of the Bay of Bengal basin
- From 1965-2017, the Bay of Bengal and Arabian sea have collectively registered 46 ‘severe cyclonic storms. Tropical cyclones in the Indian neighbourhood begin as ‘depressions’ or a gradual build-up of warm air and pockets of low pressure. About 35% of such formations intensify to ‘cyclones’ and only 7% intensify to ‘very severe cyclones’
- Cyclone Fani is expected to graduate to an ‘extremely severe cyclonic storm’ by Wednesday
- and make landfall in Orissa (as a very severe cyclonic storm)
