The name of the new cyclone that is forming on the Bay of Bengal has been named ‘Asani’. The cyclone seems to be carrying thunderstorms for the eastern coast of India which includes West Bengal, Odisha, etc.
Who named Cyclone Asani and why?
Cyclone Asani has been named by Sri Lanka. In Sinhala, one of the island country’s official languages, ‘Asani’ means wrath.
Cyclones are named by various specialised meteorological centres or warning centres to make communication simpler between forecasters and the general public. The names reduce confusion in the event of concurrent tropical storms in the same basin.
As many as six regional specialised meteorological centres (RSMCs) and five regional Tropical Cyclone Warning Centres (TCWCs) have the authority to name tropical cyclones. IMD is among the six RSMCs. IMD provides advisories to various countries including Sri Lanka, Pakistan Bangladesh, Saudi Arabia, United Arab Emirates (UAE) and Iran among others, reported the Hindustan Times.Alphabetically, these countries get to choose names. Sri Lanka chose the word “Asani” to name the tropical storm forming over the Andaman sea.As per IMD, there are 169 names that can be used for nomenclature of cyclones. India issues names for tropical cyclones forming over the north Indian Ocean, including the Arabian Sea and the Bay of Bengal.Generally, the names are assigned once the tropical storms reach 3-minute sustained wind speeds of more than 63 km/h or 39 mph.
How are cyclones formed?
Cyclogenesis plays an important role in the formation of cyclones. Wet and warm air at the surface of the ocean rises higher. This causes a zone of low pressure near the surface. Due to this, cold air from the surrounding areas flows into the area of low pressure which causes the cold air to turn warm and wet causing it to rise. The cycle continues which results in cloud development. This wind and cloud system then expand as well as rotates which culminates into a cyclone.
Anticyclones
- An anticyclone is the opposite of a cyclone i.e. i.e., it has an outward-spiralling air circulation around a high pressure centre.
- An anticyclone’s winds rotate clockwise in the Northern Hemisphere around a center of high pressure.
- In anticyclones, air comes in from above and sinks to the ground. High pressure centers generally have fair weather.
