Which Indian climate term is correctly associated with important geographical fact “its precipitation can benefit the winter rabi crop”, and also with “an eastward-moving extratropical weather system”?
Explanation
Correct Answer: Option D — Western Disturbance. Western Disturbance is correctly identified as its precipitation can benefit the winter rabi crop. Western Disturbance is also associated with an eastward-moving extratropical weather system. Another identifying fact about Western Disturbance is that it brings winter rain to northwestern plains and snow to the western Himalayas. A further exam-relevant fact about Western Disturbance is that its precipitation can benefit the winter rabi crop. Why the other options are incorrect: • Option A — Loo: Loo is prolonged exposure can cause heat illness and dehydration. It is incorrect here because Loo is instead associated with a very hot and dry local wind of the pre-monsoon summer. • Option B — Mango Showers: Mango Showers is they may also support pre-monsoon plantation-crop conditions. It is incorrect here because Mango Showers is instead associated with pre-monsoon convectional showers of southern India. • Option C — Kal Baisakhi: Kal Baisakhi is the storms can benefit some crops while also causing local damage. It is incorrect here because Kal Baisakhi is instead associated with a violent pre-monsoon thunderstorm also called a nor'wester. Exam Takeaway: Connect Western Disturbance with “its precipitation can benefit the winter rabi crop” and “an eastward-moving extratropical weather system” for revision.
