What is Cyclone?
The term 'Cyclone' is derived from Greek word 'Cyclos' which means coiling of snake. Basically, tropical cyclone is a deep low pressure area. Cyclones are created by atmospheric disturbances around a low-pressure area. Cyclones are usually accompanied by violent storms and severe weather conditions.
In the beginning the storms were named arbitrarily. An Atlantic storm that ripped off the mast of a boat named “Antje” became known as Antje’s hurricane.
Now the names of the cyclones are kept under an agreement. This initiative began in the Atlantic area in 1953 through a treaty. The tradition of giving the name of Hurricane and Cyclone in the Atlantic region continues since 1953. This was the initiative of Miami-based National Hurricane Centre.
It is known that by 1953 the name of the cyclones in Australia was named after the corrupt politicians while the USA names the cyclones on the name of females (such as Katrina, Irma etc).
If the speed of a cyclone is more than 34 nautical miles per hour then it becomes necessary to give it a special name. If the storm's wind speed reaches or crosses 74 mph, it is then classified into a hurricane/cyclone/typhoon.
Most names given in the North-Western Pacific region are not human names. Though some names have been kept in the names of men and women, but most of the names have been given on the basis of flowers, animals, birds, trees and food items etc.
World Meteorological Weather Organization and United Nations Economic and Social Commission for Asia Pacific began to name cyclonic storms since 2000.
Cyclonic storms rising in the North Indian Ocean are named by the Indian Meteorological Department.
In the Indian Ocean region 8 countries (India, Pakistan, Sri Lanka, Bangladesh, Maldives, Myanmar, Oman and Thailand) started the process of giving name to cyclonic storms since 2004 on the initiative of India. All countries contributed a set of names which are assigned sequentially on the basis of the first Alphabet of the member country.
As soon as the cyclone reaches into area of these 8 countries, predefined name is given to this cyclone. These 8 countries have suggested 8 names each.
The naming culture of the cyclones not only recognizes the threat but compels the countries to take necessary precautionary measures to mitigate the damage.
Cyclone "Okhi", which came in November 2017, was named by Bangladesh, which means "eye" in Bengali language. Recent cyclone Fani or Foni was also named by the Bangladesh. Fani means “hood of a snake”.
Till date there are 64 cyclones have been named. The list of all the cyclones in the Indian Ocean, Arabian Sea and Bay of Bengal is as follows;
Let us understand this table; In 2004 there were four cyclones; Fire, Hibru, Pyaar and Baj, similarly in 2005, 3 cyclones were; Fanoos, Mala and Mukda. In the same way, there were 4 cyclones in 2015, 3 in 2016 and 2017 only one "Okhi", which was named by Bangladesh.
The latest cyclone was Fani which was named by the Bangladesh but if the next cyclone comes in the Indian Ocean area then its name will be “Vayu” which will be named by the India which has already been decided by these 8 countries.
Similarly, the names of cyclones which will get active in 2019 and 2020 have already been decided in advance.
We hope that after reading this article you must get the clear idea that how the cyclones are named in the world and Indian Ocean?
