Which one of the following regions of India greatly benefits from the north-east trade winds in terms of good rainfall inwinter ?
Explanation
During the winter season, the north-east trade winds prevail over India, blowing from land to sea. While these winds are generally dry, they pick up moisture as they cross the Bay of Bengal [2]. This moisture-laden air causes significant rainfall along the Coromandel coast, primarily benefiting Tamil Nadu, southern Andhra Pradesh, and parts of Karnataka [3]. Tamil Nadu receives approximately 48% of its annual rainfall during this northeast monsoon period, which occurs between October and December [t1]. In contrast, the rainfall in Punjab, Haryana, and the plains of Uttar Pradesh during winter is primarily caused by western disturbances—weak temperate cyclones originating from the Mediterranean Sea—rather than the north-east trade winds [c4][t6]. Therefore, Tamil Nadu is the region that greatly benefits from the north-east trade winds for winter precipitation.
