May 10, 2022

Cyclone Asani, which developed over southeast regions of Bay of Bengal and intensified into a ‘severe cyclone’, was named by Sri Lanka. Asani means “wrath” in Sinhalese.

About:

  • In 2000, a group of nations called WMO/ESCAP (World Meteorological Organisation/United Nations Economic and Social Commission for Asia and the Pacific) decided to start naming cyclones in the region.

  • After each country sent in suggestions, the WMO/ESCAP Panel on Tropical Cyclones (PTC) finalised the list.

  • The list of 169 cyclone names released by IMD in April 2020 were provided by these countries — 13 suggestions from each of the 13 countries.

What are the guidelines to adopt names of cyclones?

  • The proposed name should be neutral to (a) politics and political figures (b) religious believes, (c) cultures and (d) gender

  • It should be short, the maximum length of the name will be eight letters

  • The names of tropical cyclones over the north Indian Ocean will not be repeated. Once used, it will cease to be used again. Thus, the name should be new.
