Today Current Affairs
Occurrence of cyclone in India:
India has a biennial cyclone season which is from March to May and October to December but on rare occasions cyclones occur in the months of June and September as well.
Cyclone Gulab became the third cyclone of the 21st century to reach the East Coast in September, after Tropical Cyclone ‘DAYE’ in 2018 and Cyclone ‘Pyaar’ of 2005. The Hindu Analysis
Generally, tropical cyclones develop during the pre-monsoon (April to June) and post-monsoon (October to December) periods in the north Indian Ocean region (Bay of Bengal and Arabian Sea).
The months of May-June and October-November are known to generate severe severe cyclones that affect the Indian coast.
Classification : The Hindu Analysis
The India Meteorological Department (IMD) classifies cyclones on the basis of their maximum sustained surface wind speed (MSW).
Cyclones are classified as Severe (MSW of 48-63 nautical miles), Very Severe (MSW of 64-89 nautical miles), Very Severe (MSW of 90-119 NM) and Super Cyclonic Storms (MSW of 120 nautical miles). One knot is 1.8 km equals per hour.
Tropical cyclone : The Hindu Analysis
A tropical cyclone is a strong circular storm that originates in warm tropical oceans and is characterized by low atmospheric pressure, high winds and heavy rain.
Typical characteristics of tropical cyclones are an area of clear skies, warm temperatures and low atmospheric pressure in the eye or center of a cyclone. The Hindu Analysis
Such storms are called hurricanes in the North Atlantic and East Pacific, and typhoons in Southeast Asia and China. They are called Tropical Cyclones in the southwest Pacific and Indian Ocean region and Willy-Willies in northwestern Australia.
The movement of these storms or cyclones is counter-clockwise in the Northern Hemisphere, that is, counter-clockwise and in the Southern Hemisphere, clockwise.
The following are favorable conditions for the formation and intensification of tropical storms:
A large sea surface with temperatures exceeding 27 °C.
Presence of the Coriolis force.
Small variation in vertical/vertical wind speed.
Pre-existing weak low-pressure area or low-level cyclone circulation.
Divergence above sea level system
