What causes rainfall on the coastal areas of Tamil Nadu in the beginning of winters?
- A.North-Eastern Monsoon
- B.Local Air Circulation
- C.Temperate Cyclones
- D.South-West Monsoon
Correct answer
Explanation
The correct answer is A, the north-east monsoon. As the monsoon retreats in October and November the wind direction reverses and air moves from the land towards the sea. Crossing the Bay of Bengal it picks up moisture and strikes the Coromandel coast, giving Tamil Nadu and coastal Andhra Pradesh their main rainy season. This is why Tamil Nadu is the one large part of India whose farming calendar depends on winter rather than summer rain.
Option B, local air circulation, produces land and sea breezes that are too small to give a season of rain. Option C, temperate cyclones, are the western disturbances, and they bring winter rain to the north-west of India, not to the far south. Option D, the south-west monsoon, leaves Tamil Nadu dry because the state lies in the rain shadow of the Western Ghats during those months.
