The name ‘Arnab’ for a tropical cyclone was suggested by Bangladesh. The list of names of tropical cyclones was prepared by WMO/ESCAP Panel on Tropical Cyclones in April 2020 for the region. The Regional Specialized Meteorological Centre in New Delhi of the IMD gives the name to a cyclone once it meets the required criteria.

The name doesn’t refer to the country of origination, the direction of its course or the country where it is going to make a landfall. The name of a cyclone proposed by Bangladesh could be used for a storm affecting India or any other country in the region.

According to the IMD, the pronunciation of the cyclone’s name is “Ornab.”
