Which Indian climate term is correctly associated with important geographical fact “Bay of Bengal depressions and cyclones can enhance its rainfall”, and also with “a seasonal wind regime associated with the retreating-monsoon period”?

Correct Answer: Option D — Northeast Monsoon. Northeast Monsoon is correctly identified as Bay of Bengal depressions and cyclones can enhance its rainfall. Northeast Monsoon is also associated with a seasonal wind regime associated with the retreating-monsoon period. Another identifying fact about Northeast Monsoon is that winds cross the Bay of Bengal and acquire moisture before reaching the southeast coast. A further exam-relevant fact about Northeast Monsoon is that Bay of Bengal depressions and cyclones can enhance its rainfall. Why the other options are incorrect: • Option A — 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. • Option B — Monsoon Trough: Monsoon Trough is depressions moving along it can produce widespread rain. It is incorrect here because Monsoon Trough is instead associated with an elongated low-pressure zone across northern India during the summer monsoon. • Option C — Western Disturbance: Western Disturbance is its precipitation can benefit the winter rabi crop. It is incorrect here because Western Disturbance is instead associated with an eastward-moving extratropical weather system. Exam Takeaway: Connect Northeast Monsoon with “Bay of Bengal depressions and cyclones can enhance its rainfall” and “a seasonal wind regime associated with the retreating-monsoon period” for revision.
