A tropical cyclone is a rapid rotating storm originating over tropical oceans from where it draws the energy to develop. It has a low pressure centre and clouds spiraling towards the eyewall surrounding the "eye", the central part of the system where the weather is normally calm and free of clouds.

The process of naming cyclones involves several countries in the region and is done under the aegis of the World Meteorological Organization (WMO).
The naming of the tropical cyclones over the north Indian Ocean commenced from September 2004, with names provided by 8 members, starting with Bangladesh, followed by India. Since then, another 5 countries have joined the Panel.
Nations that are part of this network include Bangladesh, India, Maldives, Myanmar, Oman, Iran, Pakistan, Sri Lanka, Qatar, Thailand, Saudi Arabia, United Arab Emirates and Yemen.
The Regional Specialised Meteorological Centre (RSMC), New Delhi is responsible for naming the cyclonic storms formed over the Bay of Bengal and the Arabian Sea.
There are 6 RSMCs in the world, including the Indian Meteorological Department (IMD) and 5 Tropical Cyclone Warning Centres.
The IMD is also mandated to issue advisories to 12 other countries in the region on the development of cyclones and storms.
The guidelines to name the cyclones are as follows:
1- The proposed name must be neutral to politics and political figures, religious beliefs, cultures and genders.
2- It must not hurt the sentiments of any group of people across the world.
3- It must not be rude and cruel in nature.
4- The name must be short, easy to pronounce and inoffensive to any member.
5- It must be of a maximum of eight letters and be given with its pronunciation and voice over.
6- The names of cyclones developing over the north Indian Ocean will not be repeated. Once used, it will cease to be used again.
