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.
What are the mechanism of the monsoon?
Monsoons are mainly seasonal winds that reverse their direction according to the change in season. The monsoons starts its journey from the sea to the land in summers and from land to the sea during winters, hence, are a double system of seasonal winds.
What are the five factors that affect the mechanism of Indian monsoon?
1) The differntiated heating and cooling of land and water creates low pressure on the landmass of India while the seas around experiences comparitively high prrssure. 2) The position of Inter Tropical Convergence zone (ITCZ) in summer shift over the ganga plains.
How does the Indian monsoon work?
What Causes the Monsoon in India. The monsoon is caused by differing temperature trends over the land and ocean. … During the monsoon, the wind direction reverses. Moisture-laden winds from the Indian Ocean come to fill up the void, but because they can’t pass through the Himalayas region, they’re forced to rise.
What factors are responsible for the monsoon mechanism in India?
The monsoon, which is essentially the seasonal reversal in wind direction, causes most of the rainfall received in India and some other parts of the world. The primary cause of monsoons is the difference between annual temperature trends over land and sea.
What are the factors affecting monsoon?
The major factors which affect the monsoon winds are:
- The presence of the Tibetan Plateau and the Himalayan ranges.
- The differential heating of the Indian Ocean and the landmass of Asia.
- The presence and circulation of upper air jet streams in the troposphere.
- The occurrence of snow over the Tibetan Plateau.
What are the types of monsoon in India?
India’s climate is affected by two seasonal winds – the northeast monsoon and the southwest monsoon.
There are four seasons:
- Winter (January-February)
- Hot weather summer (March-May)
- Rainy southwestern monsoon (June-September) and.
- Post-monsoon, also known as northeast monsoon in the southern Peninsula (October-December)
What is an Indian monsoon?
A monsoon is a seasonal change in the direction of the prevailing, or strongest, winds of a region. … Monsoons are most often associated with the Indian Ocean. Monsoons always blow from cold to warm regions. The summer monsoon and the winter monsoon determine the climate for most of India and Southeast Asia.
What is monsoon Class 9?
Answer: The seasonal reversal in wind direction during a year is called monsoon. Monsoon tends to have ‘breaks’ in rainfall; which means that there are wet and dry spells in between. The monsoon rains take place only for a few days at a time and then come the rainless intervals.
What are the types of monsoon?
The Types of Monsoons
- Monsoon Cycles. In India, Australia and other equatorial regions, monsoons move from cold, high pressure systems to warmer areas of less resistance with low atmospheric pressure. …
- Summer Monsoons. …
- Dry Monsoons. …
- Embryo Monsoons.
Why are Indian monsoons important?
Why is it so important to have normal rains? The monsoon is critical for agriculture in the country since nearly 60% of India’s net arable land lacks irrigation. The monsoon delivers about 70% of India’s annual rainfall and determines the yield of several grains and pulses, including rice, wheat, and sugarcane.
