Question

what is the difference between northeast monsoon and southwest monsoon?

Answer 1

Southwest winds come from the Southwest parts of the country like Kanyakumari. Northeast winds come from the Northeast parts of the country like Sikkim.

Answer 2

Southwest monsoon

The southwestern summer monsoons occur from July through September. TheThar Desert and adjoining areas of the northern and central Indian subcontinentheats up considerably 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 in to 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. Some areas of the subcontinent receive up to 10,000 mm (390 in) of rain annually.[1]

Northeast monsoon

Around September, with the sun fast retreating south, the northern land mass of the Indian subcontinent begins to cool off rapidly. With this air pressure begins to build over northern India, the Indian Ocean and its surrounding atmosphere still holds its heat. This causes cold wind to sweep down from the Himalayas andIndo-Gangetic Plaintowards the vast spans of the Indian Ocean south of theDeccan peninsula. This is known as the Northeast Monsoon or Retreating Monsoon.

While travelling towards the Indian Ocean, the dry cold wind picks up some moisture from the Bay of Bengaland pours it over peninsular India and parts of Sri Lanka. Cities like Chennai, which get less rain from the Southwest Monsoon, receive rain from this Monsoon. About 50% to 60% of the rain received by the state ofTamil Nadu is from the Northeast Monsoon.
