New Delhi: The Indian Meteorological Institute (IMD) on Tuesday expressed the possibility of cyclonic storm ‘Mocha’ hitting the southeast Bay of Bengal around May 6. IMD has given this report while studying the reports of the US weather forecast model Global Forecast System (GFS) and the European Center for Medium-Range Weather Forecast (ECMWF). Although many international meteorologists had expressed the possibility of this cyclone coming in the second week of May. At the same time, there is a possibility about the affected areas that the effect of this cyclone will be from East India to Bangladesh and Myanmar. Let us tell you how cyclones are named, in the process of naming Which countries are included, and by what other names will the storms be known in the coming times….
How did the cyclone ‘Mocha’ get its name?
Actually, in the naming of the first cyclonic storm of the year, it was to be done by ‘Yaman’ in alphabetical order. Then, on May 6, the name of the severe cyclone (Cyclone Mocha) coming into the Bay of Bengal was suggested by Yemen after the name of ‘Mocha’, a port city on its Red Sea coast.
What are cyclones?
The word ‘Cyclone’ is derived from a Greek word that means ‘coil of a snake’. It is formed by atmospheric disturbances around a low-pressure area which usually occurs with violent storms and severe weather conditions.
How do cyclones get their names?
The names of cyclones are given in two ways, in the first the names of the cyclones of the world, and in the second the names of the cyclones arising in the Arabian Sea and the Bay of Bengal. Names of Cyclones of the World Regional Specialized Meteorological Centers (RSMCs) and Tropical Cyclone Warning Centers (TCWCs) give names to cyclones that form in any ocean basin around the world. IMD also includes 6 RSMCs from around the world. The IMD names cyclones that originate in the northern Indian Ocean, including the Bay of Bengal.
The speed of cyclones is also important for naming
A cyclone is given a specific name when its speed exceeds 34 knots per hour. If the speed of a storm reaches or exceeds 74 mph, it is classified as a hurricane, cyclone or typhoon.
Naming of cyclones in the Bay of Bengal and the Arabian Sea
13 countries located in this region name the cyclones that originate in the Bay of Bengal and the Arabian Sea. In 2000, the group formed to name cyclones that originated in the region, known as WMO/ESCAP, included countries – Bangladesh, India, Maldives, Myanmar, Oman, Pakistan, Sri Lanka and Thailand – began naming. Whereas, in the year 2018, five other countries Iran, Qatar, Saudi Arabia, United Arab Emirates and Yemen joined. That is, now we name the cyclones generated in the Arabian Sea and Bay of Bengal. If there is a possibility of a storm coming, then these 13 countries have to give 13 names in sequence.
This is how the naming process goes
The countries involved in the group giving names to the cyclones generated in this region give their names alphabetically. As Bangladesh comes first from B then he will suggest the name first, then India and then Iran…. This process continues like this. For the naming of cyclones, the number of all the countries comes in turn. This time it was the turn of the name suggested by Yemen for the cyclone ‘Mocha’.
List is made for 25 years
For the next 25 years, a list is made by taking names from countries. Out of these names, names are kept in alphabetical order. The names given by the countries in the new list include Gati, Tej, Murasu (Tamil musical instrument), Aag, Neer, Prabhanjan, Ghurni, Ambud, Jaladhi and Veg. It is believed that at least 5 cyclones will come every year, on this basis the list of names is decided.
