Tropical cyclones can last for a week or more; therefore there can be more than one cyclone at a time. Naming a tropical Cyclone is a way in which Weather forecasters attempt to avoid confusion. Each year, tropical cyclones receive names in alphabetical order. Women and men’s names are alternated. The name list is proposed by the National Meteorological and Hydrological Services (NMHSs) of WMO Members of a specific region, and approved by the respective tropical cyclone regional bodies at their annual/bi-annual sessions.
Cyclones that form in every ocean basin across the world are named by the regional specialised meteorological centres (RSMCs) and Tropical Cyclone Warning Centres (TCWCs). There are six RSMCs in the world, including the India Meteorological Department (IMD), and five TCWCs.
Why name a Cyclone?
- The practice of naming storms (tropical cyclones) began years ago in order to help in the quick identification of storms in warning messages because names are presumed to be far easier to remember than numbers and technical terms.
- Many agree that appending names to storms makes it easier for the media to report on tropical cyclones, heightens interest in warnings and increases community preparedness.
- Experience shows that the use of short, distinctive given names in written as well as spoken communications is quicker and less subject to error than the older more cumbersome latitude-longitude identification methods. These advantages are especially important in exchanging detailed storm information between hundreds of widely scattered stations, coastal bases, and ships at sea.
How are the Tropical Cyclones named?
- In 2000, a group of nations called WMO/ESCAP (World Meteorological Organisation/United Nations Economic and Social Commission for Asia and the Pacific), which at the time comprised of Bangladesh, India, the Maldives, Myanmar, Oman, Pakistan, Sri Lanka and Thailand, decided to start naming cyclones in the region.he WMO/ESCAP expanded to include five more countries in 2018 — Iran, Qatar, Saudi Arabia, United Arab Emirates and Yemen.This made a total of 13 countries.
- After each country sent in suggestions, the WMO/ESCAP Panel on Tropical Cyclones (PTC) finalised the list.
- The India Meteorological Department (IMD) recently released a list of 169 names of future tropical cyclones that would emerge in the Bay of Bengal and the Arabian Sea.The list of 169 cyclone names released by IMD last month, in April, were provided by these countries — 13 suggestions from each of the 13 countries. The new list included the last name from the previous list (Amphan) as it remained unused at the time of release.
- As an RSMC, the IMD names the cyclones developing over the north Indian Ocean, including the Bay of Bengal and Arabian Sea, after following a standard procedure. The IMD is also mandated to issue advisories to 12 other countries in the region on the development of cyclones and storms.
- The nest Tropical Cyclone will e named Nisarga (by Bangladesh) and then next Gati.
- The 13 names in the recent list that have been suggested by India include: Gati, Tej, Murasu, Aag, Vyom, Jhar (pronounced Jhor), Probaho, Neer, Prabhanjan, Ghurni, Ambud, Jaladhi and Vega.
Guidelines for Naming a Tropical Cyclone:
* The proposed name should be neutral to (a) politics and political figures (b) religious believes, (c) cultures and (d) gender
* Name should be chosen in such a way that it does not hurt the sentiments of any group of population over the globe
* It should not be very rude and cruel in nature
* It should be short, easy to pronounce and should not be offensive to any member
* The maximum length of the name will be eight letters
* The proposed name should be provided with its pronunciation and voice over
* The names of tropical cyclones over the north Indian Ocean will not be repeated. Once used, it will cease to be used again. Thus, the name should be new.
