Who suggested the name 'Murasu'?
Karnataka Meteorological Department Chairman Puviarasan said that he had suggested the name 'Murasu' when he worked in Chennai Meteorological Department.
According to BBC Tamil, in a video released in this regard, he told that the World Meteorological Organization (WMO) has set some guidelines for naming storms.
According to these guidelines, the name of the storm should not be associated with any religion or politics. It should also not be the name of any private person. The name should be such that it does not hurt anyone's sentiments. It should be easy to pronounce and should not contain more than eight letters. Also, it should be connected to the common people in some way or the other.
Puviarasan says that the name 'Murasu' was suggested keeping these rules in mind.
He told that in ancient times, during the rule of kings, Murasu was used to convey messages to the people in public. During disasters, it was also used to inform people about important announcements and messages. Therefore, a name was chosen which is associated with the common people and which can be easily identified.
Puviarasan told that apart from 'Murasu' he had also suggested some other names. These included the names of 'Er' and 'Kalappai' related to farming. Apart from this, the names 'Nawai' and 'Patagu' related to sea and fishing industry were also suggested. He also suggested the name of a fish named 'Tirukkai'.
He told that among these names, the Indian Meteorological Department finally chose the name 'Murasu'.
How are cyclones named?
The United Nations Economic and Social Commission for Asia and the Pacific (ESCAP) and the World Meteorological Organization (WMO) introduced a system of naming cyclones that form in the Bay of Bengal and the Arabian Sea in 2000.
Under this, a group of countries like Bangladesh, India, Maldives, Myanmar, Oman, Pakistan, Sri Lanka and Thailand submitted a list of 13 names for cyclones arising in the Bay of Bengal and the Arabian Sea.
In 2018, the names of Iran, Qatar, Saudi Arabia, United Arab Emirates and Yemen were also added to the panel of these countries. The job of this panel is to decide the names of cyclones.
The names suggested by these countries are listed alphabetically by country name. This list starts from Bangladesh.
Then after this the names of India, Iran, Maldives, Oman, Pakistan come in it.
Cyclones are named according to this order. After Cyclone Nivar in 2020, the names of the cyclones that are going to be heard are Burevi (Maldives), Tauktae (Myanmar), Yaas (Oman) and Gulab (Pakistan).
In April 2020, a new list containing these names was approved by the member countries.
