  • Cyclone Fani, is the first severe, cyclonic storm to have formed in April in India’s oceanic neighbourhood since 1976, according to the records of the India Meteorological Department (IMD).
  • According to IMD, it is a consequence of global warming and it is forming due to the warming of the Bay of Bengal basin.
  • Data from the IMD’s cyclone-statistics unit show that the Bay of Bengal and Arabian Sea have collectively registered 46 severe cyclonic storms in between 1965-2017.
  • 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.
  • The IMD ranks cyclones on a 5-point scale.
