Why is there a difference in precipitation during a summer and winter moonsoon?

The difference in precipitation during summer and winter monsoons is primarily due to variations in atmospheric conditions and temperature. During the summer monsoon, intense heating of land leads to low-pressure systems, drawing in moisture-laden winds from the ocean, resulting in heavy rainfall. In contrast, the winter monsoon is characterized by cooler temperatures and high-pressure systems over land, causing drier air to flow from the land to the sea, which results in significantly less precipitation. These seasonal shifts in pressure and temperature drive the contrasting rainfall patterns associated with each monsoon phase.
