Background:

The World Meteorological Organisation (WMO) maintains rotating lists of names.

The word Tauktae has been suggested by Myanmar, which means ‘gecko’, a distinctively vocal lizard, in the Burmese language.

  • The name is the fourth from a new list of 169 names released by the IMD last year.

How are cyclones named?

  • A WMO/ESCAP (World Meteorological Organisation/United Nations Economic and Social Commission for Asia and the Pacific) Panel on Tropical Cyclones agreed in principle to assign names to the tropical cyclones in the Bay of Bengal and the Arabian Sea during its 27th session held in Muscat, Sultanate of Oman, in 2000.
  • The naming of the tropical cyclones over the north Indian Ocean commenced from September 2004, with names provided by eight members, starting with Bangladesh, followed by India. Since then, another five countries have joined the Panel.
  • The Regional Specialised Meteorological Centre (RSMC), New Delhi is responsible for naming the cyclonic storms formed over the Bay of Bengal and the Arabian Sea when they reach the relevant intensity.

There are six RSMCs in the world, including the IMD and five Tropical Cyclone Warning Centres.
