Tamil Nadu Coast receives rainfall during winter season due to

The correct answer is (A) Retreating of South-west Monsoon

The Tamil Nadu coast receives most of its rainfall during the winter season (October–December) due to the retreating (northeast) monsoon winds.

These winds blow from land to sea but pick up moisture from the Bay of Bengal, causing rainfall on the Tamil Nadu coast.

This is why Tamil Nadu gets less rainfall in the southwest monsoon but more during the retreating monsoon.

The retreating monsoon is also called the Northeast Monsoon.

It is crucial for agriculture in Tamil Nadu, especially for crops like rice and pulses.

Cyclonic depressions in the Bay of Bengal during this period enhance rainfall.

South-west Monsoon:

Brings heavy rainfall to most of India but gives limited rain to Tamil Nadu due to its location in the rain shadow region.

Western Disturbance:

Affects northwestern India in winter, not Tamil Nadu.
