- The coast of north Tamil Nadu was traversed by Cyclone Mandous, which had strong gusts and torrential rain.
- United Arab Emirates, a member of the WMO, proposed the name Cyclone Mandous, which is pronounced “Man-Dous.”
- In Arabic, it denotes a “treasure box.”
Tropical Cyclones
- A tropical cyclone is a powerful circular storm with low air pressure, strong winds, and heavy rain that develops over warm tropical waters.
- Over slightly warm ocean waters, cyclones form. To enable the formation of a cyclone, the sea’s surface temperature must be at least 28°C up to a depth of roughly 60 metres.
- This explains why cyclone season occurs between April and May and October and December.
- The low level of air above the waters must then rotate “anticlockwise.”
- During these times, there is an ITCZ in the Bay of Bengal with winds running from west to east along its southern boundary and from east to west along its northern boundary.
- Cyclones in this region typically migrate northwest after forming. The cyclone picks up additional humid air from the warm water as it passes over the ocean, adding to its weight.
Conditions for the formation of a cyclone
The following six conditions are necessary for tropical cyclogenesis:
- Warm enough sea surface temperatures
- Climatic instability
- High levels of humidity in the lower to middle troposphere
- Sufficient Coriolis force to create a centre of low pressure
- A low-level focus or disruption that was present before
- Very little vertical wind shear
Naming of Cylcones
- The World Meteorological Organization and the United Nations Economic and Social Commission for Asia and the Pacific decided to give cyclones names in 2000.
- It was decided to begin naming cyclones in the area by Bangladesh, India, the Maldives, Myanmar, Oman, Pakistan, Sri Lanka, and Thailand.
- The list was finalised by the WMO/ESCAP Panel on Tropical Cyclones (PTC) after each nation submitted suggestions.
- In 2018, Iran, Qatar, Saudi Arabia, the United Arab Emirates, and Yemen were added to the WMO/ESCAP.
