Which of the following statements accurately explains the phenomenon of the winter rainfall experienced in the coastal districts of Tamil Nadu?
A. Southwest monsoon winds blowing from the Arabian Sea strike the Nilgiri hills and drop moisture.
B. Retreating southwest monsoon winds pick up moisture from the Bay of Bengal and strike the eastern coast.✓ Correct Answer
C. Western disturbances originating in the Mediterranean region travel eastward across northern India to reach Tamil Nadu.
D. Local sea breeze circulation interacting with tropical cyclones forming in the Arabian Sea.
💡 Solution & Explanation
Tamil Nadu receives a significant portion of its annual rainfall during the northeast monsoon season between October and December, as the retreating southwest monsoon wind system reverses direction and blows northeast-to-southwest across the Bay of Bengal, picking up moisture and depositing rain upon the eastern coastal plains. Western disturbances bring winter precipitation primarily to northwestern India. The southern peninsula relies heavily on this cyclonic and northeast monsoon rainfall regime for agricultural recharge.
