what are the phenomena associated with the monsoons in India explain them with reference to the assisting forces of atmospheric pressure and wind the ocean current monsoon trough Ferrel's law etc...
Answers
Answer:
Indian Monsoons are Convection cells on a very large scale. They are periodic or secondary winds which seasonal reversal in wind direction. India receives south-west monsoon winds in summer and north-east monsoon winds in winter.
Annual average monsoon precipitation in India over 110 years. The long-term average has been 899 millimeters of precipitation.[1] However, the monsoon varies over the Indian subcontinent within a ±20% range. Rains that exceed 10% typically lead to major floods, while a 10% shortfall is a significant drought.[2]
The monsoon of South Asia is among several geographically distributed global monsoons. It affects the Indian subcontinent, where it is one of the oldest and most anticipated weather phenomena and an economically important pattern every year from June through September, but it is only partly understood and notoriously difficult to predict. Several theories have been proposed to explain the origin, process, strength, variability, distribution, and general vagaries of the monsoon, but understanding and predictability are still evolving.
The unique geographical features of the Indian subcontinent, along with associated atmospheric, oceanic, and geophysical factors, influence the behavior of the monsoon. Because of its effect on agriculture, on flora and fauna, and on the climates of nations such as Bangladesh, Bhutan, India, Nepal, Pakistan, and Sri Lanka — among other economic, social, and environmental effects — the monsoon is one of the most anticipated, tracked,[3] and studied weather phenomena in the region. It has a significant effect on the overall well-being of residents and has even been dubbed the "real finance minister of India".[4][5]
