Why do seasonal reversal of wind takes place over the Indian subcontinent?

The seasonal reversal of winds over the Indian subcontinent is primarily due to the differential heating of land and water. During summer, the land heats up rapidly compared to the surrounding ocean, creating low pressure over the continent and drawing in moisture-laden winds from the southwest, resulting in the southwest monsoon. Conversely, in winter, the land cools more quickly, leading to high pressure, which causes cold, dry winds to blow from the northeast. This shift in pressure systems and temperature differences drives the monsoon cycle and the seasonal wind patterns.
