GENERAL KNOWLEDGE

Detailed explanation-1: -The dry winter monsoon blows from the northeast. These winds start in the air above Mongolia and northwestern China. Winter monsoons are less powerful than summer monsoons in Southeast Asia, in part because the Himalaya Mountains prevent much of the wind and moisture of the monsoons from reaching the coast.

Detailed explanation-2: -Monsoonal precipitation reaches the Himalaya beginning in the eastern sector then moving westward. During the course of the Southwest Monsoon there are periods when the monsoon trough moves northward over Nepal, and precipitation over much of India decreases.

Detailed explanation-3: -Monsoons are driven by the land-sea thermal contrast as the continent heats up and cools down faster than the ocean. Thus, in summer, land reaches a higher temperature than the ocean and the hot air over the land tends to rise, creating an area of persistent low pressure.
