what are Monsoon winds ?describe the South West monsoon of the Indian subcontinent
Answers
This causes a complete reversal of the direction of winds during summer.
Air moves from the high-pressure area over the southern Indian Ocean, in a south-easterly direction, crosses the equator, and turns right towards the low-pressure areas over the Indian subcontinent.
These are known as the Southwest Monsoon winds.
These winds blow over the warm oceans, gather moisture and bring widespread rainfall over the mainland of India.
Answer:
Because of high temperatures in summers, low pressure area develop in Punjab plains and Thar desert of Rajasthan. This attracts the winds blowing from the high pressure area in the Indian Ocean which starts blowing towards the mainland of India. These moisture laden winds bring rainfall because of the obstruction caused by the Western and Eastern Ghats, it rains more in the coastal areas. This rainfall reduces in the leeward side of the hills. As this winds blow parallel to Aravalis. As a result rainfall is low in parts of Gujarat and Rajasthan. Later these winds move towards the Himalayas. their moisture carrying capacity increase. Orographic type of rainfall occurs because of natural obstruction of the Himalayas. This winds return from the Himalayas and their retreating journey starts.
