The primary reason for the seasonal reversal of winds, which characterizes the monsoon, is the differential heating and cooling rates of land and water. During summer, the land heats up much faster and to a higher temperature than the surrounding seas, creating a low-pressure area over the Indian subcontinent. This draws moisture-laden winds from the high-pressure area over the oceans. In winter, the land cools faster, creating high pressure, and the winds reverse. While the Himalayas influence precipitation distribution and the ITCZ is associated with monsoon trough, differential heating is the fundamental driver of the wind reversal.
