What is a tropical cyclone?
A tropical cyclone is a low-pressure system with very high winds moving around it. These cyclones occur in the region between 5-35° latitude north or south of the equator. The tropical cyclone moves in an anticlockwise direction in the northern hemisphere and clockwise in the southern hemisphere.
The centre of the tropical cyclone is often dry and is called an eye. It is the low-pressure centre.
The tropical cyclones are called willy-willy in Australia, Typhoons in China and Japan, Hurricanes in West Indies and the coast of Florida and Tornadoes in the USA and Mexico.
Certain conditions are required for the formation of tropical cyclones: High sea surface temperature (more than 26 °C), atmospheric instability, high humidity, and sufficient Coriolis force.
Cyclones cause large-scale destruction owing to very heavy rainfall, high-speed winds and storm surges.
Naming of Cyclones - How are Cyclones Named?
The name of this tropical cyclone "SITRANG" has been given by Thailand. The naming of the tropical cyclones over the north Indian Ocean started in September 2004. Regional Specialised Meteorological Centres (RSMCs) and Tropical Cyclone Warning Centres (TCWCs) name the cyclones formed in every basin across the globe.
There are a total of 6 RSMCs including the Indian Meteorological Department (IMD) and 5 TCWCs that provide tropical cyclone and storm surge advisories to 13 member countries under the WMO/ESCAP Panel. These 13 countries are India, Iran, Bangladesh, Maldives, Oman, Myanmar, Pakistan, Qatar, Saudi Arabia, Thailand, Sri Lanka, UAE and Yemen. The names of tropical cyclones are not repeated.
