Climate of India Questions and Answers

Correct Answer: Option D — La Nina. La Nina is correctly identified as La Nina should not be treated as a guaranteed cause of uniform excess rain across India. La Nina is also associated with the cool phase of the El Nino-Southern Oscillation. Another identifying fact about La Nina is that it alters tropical atmospheric circulation and can influence the Indian monsoon. A further exam-relevant fact about La Nina is that La Nina should not be treated as a guaranteed cause of uniform excess rain across India. Why the other options are incorrect: • Option A — Southwest Monsoon: Southwest Monsoon is its advance and withdrawal organize much of India's rainy season. It is incorrect here because Southwest Monsoon is instead associated with the principal rain-bearing seasonal wind system of India. • Option B — Northeast Monsoon: Northeast Monsoon is Bay of Bengal depressions and cyclones can enhance its rainfall. It is incorrect here because Northeast Monsoon is instead associated with a seasonal wind regime associated with the retreating-monsoon period. • Option C — Inter-Tropical Convergence Zone: Inter-Tropical Convergence Zone is over northern India its monsoon-season position is linked with the monsoon trough. It is incorrect here because Inter-Tropical Convergence Zone is instead associated with a low-pressure belt where trade-wind systems converge. Exam Takeaway: Connect La Nina with “La Nina should not be treated as a guaranteed cause of uniform excess rain across India” and “the cool phase of the El Nino-Southern Oscillation” for revision.

Correct Answer: Option C — La Nina. La Nina is correctly identified as it alters tropical atmospheric circulation and can influence the Indian monsoon. La Nina is also associated with La Nina should not be treated as a guaranteed cause of uniform excess rain across India. Another identifying fact about La Nina is that it alters tropical atmospheric circulation and can influence the Indian monsoon. A further exam-relevant fact about La Nina is that La Nina should not be treated as a guaranteed cause of uniform excess rain across India. Why the other options are incorrect: • Option A — Southwest Monsoon: Southwest Monsoon is the Western Ghats cause strong orographic rainfall on their windward side. It is incorrect here because Southwest Monsoon is instead associated with its advance and withdrawal organize much of India's rainy season. • Option B — Northeast Monsoon: Northeast Monsoon is winds cross the Bay of Bengal and acquire moisture before reaching the southeast coast. It is incorrect here because Northeast Monsoon is instead associated with Bay of Bengal depressions and cyclones can enhance its rainfall. • Option D — Inter-Tropical Convergence Zone: Inter-Tropical Convergence Zone is rising warm moist air encourages cloud formation and convection. It is incorrect here because Inter-Tropical Convergence Zone is instead associated with over northern India its monsoon-season position is linked with the monsoon trough.

Correct Answer: Option B — La Nina. La Nina is correctly identified as it involves unusual cooling in the central and eastern equatorial Pacific. La Nina is also associated with it alters tropical atmospheric circulation and can influence the Indian monsoon. Another identifying fact about La Nina is that it alters tropical atmospheric circulation and can influence the Indian monsoon. A further exam-relevant fact about La Nina is that La Nina should not be treated as a guaranteed cause of uniform excess rain across India. Why the other options are incorrect: • Option A — Southwest Monsoon: Southwest Monsoon is it reaches India from the Arabian Sea and Bay of Bengal sectors. It is incorrect here because Southwest Monsoon is instead associated with the Western Ghats cause strong orographic rainfall on their windward side. • Option C — Northeast Monsoon: Northeast Monsoon is it is especially important for rainfall over coastal Tamil Nadu. It is incorrect here because Northeast Monsoon is instead associated with winds cross the Bay of Bengal and acquire moisture before reaching the southeast coast. • Option D — Inter-Tropical Convergence Zone: Inter-Tropical Convergence Zone is its seasonal northward shift influences the Indian summer monsoon. It is incorrect here because Inter-Tropical Convergence Zone is instead associated with rising warm moist air encourages cloud formation and convection. Exam Takeaway: Connect La Nina with “it involves unusual cooling in the central and eastern equatorial Pacific” and “it alters tropical atmospheric circulation and can influence the Indian monsoon” for revision.
