  • Seasonal reversal of wind direction takes place over the Indian subcontinent?

    Answer: Seasonal reversal of wind direction over the Indian subcontinent takes place due to pressure differential. El Nino has major role to play in the seasonal reversal of wind direction over the Indian subcontinent.
  • The bulk of rainfall in India is concentrated over a few months.

    Answer: The monsoon begins from the first week of June and advances quite rapidly to cover almost the whole country by mid-July. Hence, the bulk of rainfall in India is concentrated over the months of a few months; mainly June to August.
  • The Tamil Nadu coast receives winter rainfall.

    Answer: The Tami Nadu coast receives winter rainfall because of movement of low-pressure conditions to the Bay of Bengal.
  • The delta region of the eastern coast is frequently struck by cyclones.

    Answer: The Bay of Bengal is the centre of various pressure changes and hence there is always a chance of development of cyclone. Due to this, the delta region of the eastern coast is frequently struck by cyclones.
  • Parts of Rajasthan, Gujarat and the leeward side of the Western Ghats are drought-prone.

    Answer: These parts fall in the rain shadow area of the Aravalli. Hence, they are drought prone.
