Question

Why does the northeast trade wind become dominant when the Sun moves towards the Tropic of Capricorn from the Tropic of Cancer?

• A. Because of the high pressure area created over Indian ocean and the low pressure area created over the south of the Bay of Bengal.
• B. Because of the low pressure area created over Central Asia and the high pressure area shifted over to the north of the Bay of Bengal.
• C. Because of the high pressure area created over Central Asia and the low pressure area shifted over to the north of the Bay of Bengal.
• D. Because of the high pressure area created over Central Asia and the high pressure area created over the north of the Bay of Bengal.

Answer 1

The correct option is C Because of the high pressure area created over Central Asia and the low pressure area shifted over to the north of the Bay of Bengal.

When the Sun moves towards the Tropic of Capricorn from the Tropic of Cancer, the low-pressure area over the Indian subcontinent weakens and the monsoon vanishes. During this time, a high-pressure zone is created over Central Asia, and the low-pressure area gets transferred to the northern parts of Bay of Bengal, causing the northeast trade wind to be more dominant.
