The economic significance of the monsoon is aptly described by Pranab Mukherjee's remark that the monsoon is the "real finance minister of India". [ 4 ] [ 5 ] A good monsoon results in better agricultural yields, which brings down prices of essential food commodities and reduces imports, thus reducing food inflation overall. [ 48 ]
A monsoon (/ m ɒ n ˈ s uː n /) is traditionally a seasonal reversing wind accompanied by corresponding changes in precipitation [1] but is now used to describe seasonal changes in atmospheric circulation and precipitation associated with annual latitudinal oscillation of the Intertropical Convergence Zone (ITCZ) between its limits to the north and south of the equator.
It also causes pre-monsoon rainfall especially in northern India. [citation needed] The interaction of the monsoon trough with western disturbances may occasionally cause dense clouding and heavy precipitation. The 2013 North India floods, which killed more than 5000 people in a span of 3 days, is said to be a result of one such interaction. [5]
Floods are the most common natural disaster in India. The heavy southwest monsoon rains cause the Brahmaputra and other rivers to distend their banks, often flooding surrounding areas. Though they provide rice paddy farmers with a largely dependable source of natural irrigation and fertilisation, the floods can kill thousands and displace millions.
The devastation of this year's monsoon season in India, which runs from June to September, has been significant: Local government estimates say that 428 people have died and Himachal Pradesh ...
During the Triassic period of 251–199.6 Ma, the Indian subcontinent was the part of a vast supercontinent known as Pangaea.Despite its position within a high-latitude belt at 55–75° S—latitudes now occupied by parts of the Antarctic Peninsula, as opposed to India's current position between 8 and 37° N—India likely experienced a humid temperate climate with warm and frost-free weather ...
The North-East monsoon is responsible for 10%-20% rainfall of the total rainfall in India, while the South-West monsoon provides approximately 80% of rainfall. Therefore, the effects of climate change on the monsoon seasons is one of the important reasons for decrease in rainfall and water shortage in India.
The South Asian monsoon season, which spans from June to September, typically brings about 80% of annual rainfall to the region. [8]In recent years, India has witnessed intensified weather patterns, with the monsoon season becoming more erratic and less dependable over time. [9]
