Question
Consider the following statements The South-West monsoon originates in India due to
Which of the statements given above are correct?
- low pressure in the Punjab plain.
- high pressure in areas South of India
- equatorial low being filled up by descending air current.
- the Himalayas.
Which of the statements given above are correct?
Answer: Option D
Answer: (d)
Southwest monsoon is the main mechanism through which nearly all Indian landmass experience rainfall. It accounts for nearly 80% rainfall of whole India.
The vast size of the Indian continent helps in developing the thermal gradient necessary to attract the vapour laden air from the sea. Very high and extensive mountain systems of the Himalayas in the north, extending in an east-west direction, thus posing a formidable physical barrier between tropical and polar air masses.
These barriers induce the precipitation of water from moisture-laden air. As the air climb up the Himalayas their moisture retention capacity decreases due to the cooling effect and this results in high rainfall.
