Air moves from the high-pressure area over the southern Indian Ocean in a south-easterly direction and turn right towards low pressure areas over the Indian subcontinent. These we know as the ____________ winds.

Correct option is C

The correct answer is (c) South-West Monsoon

The South-West Monsoon winds are a seasonal wind system that brings significant rainfall to the Indian subcontinent. These winds result from a complex interaction between high-pressure and low-pressure zones.

How it Works:

• High-Pressure Area:

  • During summer (June to September), a high-pressure system develops over the southern Indian Ocean.

• Low-Pressure Area:

  • The intense heat over the Indian subcontinent creates a low-pressure zone.

• Wind Movement:

  • Air moves from the high-pressure area over the southern Indian Ocean to the low-pressure area over the Indian subcontinent.
  • Due to the Earth's rotation (Coriolis effect), the winds deflect to the right in the Northern Hemisphere and move in a south-westerly direction.

• Moisture-Laden Winds:

  • As the winds cross the warm Indian Ocean, they pick up moisture, causing heavy rainfall upon reaching the Indian landmass.

• Easterly Winds: Blow from east to west but are not associated with monsoon patterns.
• Westerly Winds: Blow from west to east in the mid-latitudes, unrelated to the monsoon.
• Trade Winds: Blow from east to west in tropical regions but do not turn northward to bring monsoon rains.
