NEW DELHI: Mala, Helen, Nargis and Nilofer may sound like the names of yesteryear Bollywood actors, but  they are, in fact, lethal cyclones that have brought violent winds, heavy rains and wreaked destruction.

As Cyclone Fani pounded the Odisha coast on Friday, the name, which was suggested by Bangladesh, also evoked curiosity.

Mritunjay Mohapatra, the additional director general of the India Meteorological Department (IMD), said Fani, pronounced as ‘Foni’, means a snake’s hood.

But how are cyclones named?

The World Meteorological Organisation/Economic and Social Commission for Asia and the Pacific Panel on Tropical Cyclones, at its twenty-seventh session held in 2000 in Muscat, Oman, agreed to assign names to the tropical cyclones in the Bay of Bengal and Arabian Sea.

After long deliberations among the member countries, the naming of tropical cyclones over north Indian Ocean commenced from September 2004.

The eight countries along the Bay of Bengal and Arabian Sea suggest names that are sequentially listed. The nations suggest names alphabetically — Bangladesh, India, Maldives, Myanmar, Oman, Pakistan, Sri Lanka and Thailand.

The Regional Specialised Meteorological Centre (RSMC) based here gives a tropical cyclone an identification from the names list. The identification system covers both the Arabian Sea and the Bay of Bengal.

So, for instance, Bangladesh suggested ‘Onil’ the first in the list. Onil originated in Arabian Sea, off the Gujarat coast between September to October 2004. It made landfall in the state, but impacted both India and Pakistan.

Cyclone Phetai, suggested by Thailand, originated in the Bay of Bengal and made landfall in Andhra Pradesh, ravaging the coastal districts in December last year.

The next cyclone, whenever it originates, will be named ‘Vayu’, suggested by India. (AGENCIES)
