Question

Difference between north east monsoon and south west monsoon

Answer 1

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 subcontiAround 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 Plain towards 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
