But first, what is a cyclone?
The term ‘Cyclone’ comes from the Greek word Cyclos which means a coiling snake. It is a system of wind rotating inwards around a low-pressure area. Caused by atmospheric disturbance, cyclones are usually accompanied by severe weather conditions such as storms.
When are Cyclones named?

The naming of cyclones is done by World Meteorological Organization/United Nations Economic and Social Commission for Asia and the Pacific (WMO/ESCAP) Panel on Tropical Cyclones (PTC), according to an NDTV report.
Thirteen countries on the panel, including India, Bangladesh, Myanmar, Pakistan, the Maldives, Oman, Sri Lanka, Thailand, Iran, Qatar, Saudi Arabia, United Arab Emirates and Yemen, name cyclones in the region. In 2020, a new list of names was released that had 169 names of cyclones, having 13 suggested names each from 13 countries.
