Consider the following statementsThe South-West monsoon originates in...
- The southwest Monsoon brings rains towards the end of summer as the high pressure built in the Indian Ocean pushes the wind masses towards the low pressure formed on land.
- The southwestern summer Monsoons occur from July through September. Northern and central Indian subcontinent heats up during the hot summers.
- This causes a low-pressure area over the northern and central Indian subcontinent. To fill this void, the moisture-laden winds from the Indian Ocean rush into the subcontinent.
- These winds, rich in moisture, are drawn towards the Himalayas. The Himalayas act like a high wall, blocking the winds from passing into Central Asia and forcing them to rise. As the clouds rise their temperature drops and precipitation occurs.

Consider the following statementsThe South-West monsoon originates in...
Origin of South-West Monsoon in India
There are four statements given regarding the origin of South-West monsoon in India. Let's discuss each statement in detail:
1. Low pressure in the Punjab plain
- The South-West monsoon winds blow towards India from the Indian Ocean. As they reach the Indian subcontinent, they are deflected towards the low-pressure area over the Punjab plains.
- This low-pressure area is created by the intense heat of the summer months and the Himalayan mountain range that blocks the monsoon winds from moving towards the north.
- Therefore, the statement 1 is correct.
2. High pressure in areas South of India
- The South-West monsoon winds blow towards India from the Indian Ocean. As they reach the Indian subcontinent, they are deflected towards the low-pressure area over the Punjab plains.
- There is no high pressure in areas South of India that can affect the origin of South-West monsoon in India.
- Therefore, the statement 2 is incorrect.
3. Equatorial low being filled up by descending air current
- The South-West monsoon winds originate from the equatorial low-pressure area over the Indian Ocean.
- As the landmass of India heats up during summer, a low-pressure area is created in the Punjab plains which attracts the monsoon winds towards it.
- Therefore, the statement 3 is incorrect.
4. The Himalayas
- The Himalayan mountain range acts as a barrier for the South-West monsoon winds, preventing them from moving towards the north.
- The monsoon winds are deflected towards the low-pressure area over the Punjab plains due to the Himalayas, which plays a crucial role in the origin of South-West monsoon in India.
- Therefore, the statement 4 is correct.
Conclusion
From the above discussion, we can conclude that the correct statements regarding the origin of South-West monsoon in India are 1 and 4, i.e., the low pressure in the Punjab plain and the Himalayas.
