The very high rainfall in the Khasi Hills is linked with which monsoonal process?
Answer and explanation
Correct answer: Orographic lifting of moist winds
The governing climate concept is orographic rainfall. Moist air from the Bay of Bengal branch of the southwest monsoon moves toward the north-eastern hills. When this air encounters the Khasi Hills, it is forced to rise along the slopes. Rising air cools, water vapour condenses, and intense rainfall occurs on the windward side. Hence option A is correct. Glacial deposition, lava flow, and sand storms are not mechanisms that produce monsoonal rainfall. Cherrapunji and Mawsynram are well-known examples of places receiving exceptional rainfall because of this combination of moist monsoon flow and relief-induced uplift.
