The North-East Monsoon winds blow from the land area of northeastern India toward the ocean. As they cross the Bay of Bengal, they absorb moisture and cause heavy rainfall along the Coromandel Coast of Tamil Nadu between October and December.

Adım Adım Çözüm

Identify the geographical region and seasonal timing mentioned in the stem.

The target region is the Coromandel Coast (Tamil Nadu) and the season is winter (October to December).

Rainfall patterns in India vary significantly across regions and seasons due to changing wind regimes.

Analyze the prevailing wind directions and moisture sources during the autumn/winter transition.

As the apparent position of the Sun shifts southwards, high pressure develops over Northern India and winds blow northeast to southwest (North-East Monsoon).

These winds cross the Bay of Bengal, pick up moisture, and strike the eastern coast of Tamil Nadu.

Select the option that correctly describes this wind system.

North-East Monsoon winds are the primary mechanism for winter rainfall on the Coromandel Coast.

This matches the seasonal wind reversal phenomenon of the Indian subcontinent.
