NAMING OF TROPICAL CYCLONES IN NORTH INDIAN OCEAN

 

 

Background

The World Meteorological Organisation (WMO) and the United Nations Economic and Social Commission for Asia and the Pacific (ESCAP) started the tropical cyclone naming system in 2000. Tropical cyclones are named to provide ease of communication between forecasters and the general public regarding forecasts, watches, and warnings.

Worldwide naming of Cyclones

The Cyclones worldwide are named by 9 regions — North Atlantic, Eastern North Pacific, Central North Pacific, Western North Pacific, North Indian Ocean, South West Indian Ocean, Australian, Southern Pacific, South Atlantic.

Naming in the North Indian Ocean

Cyclones in the North Indian Ocean basin are named by the Indian Meteorological Department and the first tropical cyclone was named in 2004 as Onil (given by Bangladesh).

Eight north Indian Ocean countries — Bangladesh, India, the Maldives, Myanmar, Oman, Pakistan, Sri Lanka and Thailand, gave eight names each which was combined into a list of 64 names. One name from each country is picked in an order to name the cyclones.
