Correct:
C
Explanation
The correct answer is Option 3: Western disturbances. While all four phenomena influence Indian weather, Western Disturbances are primarily associated with the winter season rather than the monsoon climate.
- Western Disturbances: These are extra-tropical cyclones originating over the Mediterranean Sea. They bring sudden winter rain to the north and northwestern parts of India. Since they occur during the winter months (December–February), they are not a driver or component of the summer monsoon system.
- El Niño (Option 1): This involves the warming of central and eastern tropical Pacific waters, which weakens the trade winds and is historically linked to deficient monsoon rainfall in India.
- South-equatorial warm currents (Option 2): The heating of the Indian Ocean and the resultant pressure gradients are fundamental to the onset and intensity of the moisture-laden Southwest Monsoon winds.
- Cyclones of Bay of Bengal (Option 4): Tropical cyclones originating in the Bay of Bengal during the monsoon and retreating monsoon phases are crucial for the spatial distribution of rainfall across the eastern coast and interior peninsula.
