The naming of Tropical cyclones in the Indian Ocean region given by 8 pannel member countries  (India, Pakistan, Sri Lanka, Bangladesh, Maldives, Myanmar, Oman, and Thailand).

Cyclones:

A cyclone is a rotating of winds anti-clockwise in the Northern Hemisphere around a low-pressure center area seas and oceans. The air rises over and cools, creating clouds and precipitation.

The winds of this are blows in a circular manner in the anticlockwise direction in the Northern hemisphere and clockwise direction in the Southern hemisphere.

On the other hand, in tropical regions, they occur due to intense heating up of air in some regions causing very low pressure in these locations. Tropical seas and oceans are most conducive to the development of Tropical Cyclones.

Low pressure and atmospheric instability turn to cyclone if the temperature of water at the sea level rises above 26.5 degrees Centigrade and there is the high relative humidity of the atmosphere at a height of more than 700 m.

The low-pressure areas, the pressure of air increasing outward, and closed air circulation from outside towards the central low pressure in such a way that air blows inward in the anticlockwise direction in the Northern hemisphere and in the clockwise direction in the Southern hemisphere.

Eye of the cyclone:

The eye of the cyclone lies in the center of the cyclone. It has abnormally high temperatures and the lowest pressure. The general direction of cyclones in the Bay of Bengal is from east to west.

Cyclones are mainly of two types-

1. Tropical Cyclone
2. Temperate Cyclone

1.Tropical cyclone:

• They are found in the trade wind belt, between 8-20 degrees North and South.
• It travels from East to West in the Easterly wind belt.
• Tropical cyclones are much smaller with a diameter of about 200 to 500 km.
• Tropical cyclones are non-frontal in nature.
• It is formed only over the oceans.
• A tropical cyclone can form only in the summer.

2.Temperate Cyclone:

• Normally found between 30 to 65 degrees North and South in the subpolar frontal zone, where cold polar air mass meets the warm tropical air mass.
• It moves from West to East embedded in the Westerly wind belt.
• They form over a much large area with a diameter of 300 to 1500 km.
• Temperate cyclones are frontal in nature.
• They can form both in summer as well as in winter.
• It is formed either over continents or over the oceans.

All names of the cyclone are given below in Table.

Northern Indian Ocean (45°E-100°E) Names – In the Arabian Sea and the Bay of Bengal:

Cyclone rising in the North Indian Ocean is named through the Indian Meteorological Department (IMD) is an agency of the Ministry of Earth Sciences of the Government of India and  8 Member countries pannel.

Now 5 countries joined as member panel. The headquarters of IMD in Delhi and Regional offices are at Mumbai, Kolkata, Nagpur, and Pune.

The naming of the tropical cyclones over the north Indian Ocean commenced from September 2004, with names provided by eight Members (India, Pakistan, Sri Lanka, Bangladesh, Maldives, Myanmar, Oman, and Thailand).

Since 2004 on the initiative of India started the process of giving the name to cyclonic storms in the Indian Ocean region by 8 countries (India, Pakistan, Sri Lanka, Bangladesh, Maldives, Myanmar, Oman, and Thailand).

Now 5 countries joined as member pannel. From 2020 after Amphan cyclone, names are provided by Thirteen (13) Countries. These are Bangladesh, India, Iran, Maldives,Myanmar, Oman, Pakistan, Qatar, Saudi Arabia, Sri Lanka, Thailand, U.A.E., and Yemen
