Origin of Monsoon winds
Depending on the season, different directions produce monsoon winds. Monsoon winds originate at sea and move inland during the summer. Air over land goes out to sea while the wind is blowing the other way during the winter.
The difference in heat capacity between land masses and ocean water causes monsoons. The summer sun’s heat heats the land far more quickly than it warms the oceans, and as the land quickly cools, it radiates heat back into the atmosphere above it. During the summer, this causes the warm air over landmasses to expand and rise, drawing moist air from the oceans, which also rises. When the moist air from the oceans condenses into clouds, it produces the monsoons’ torrential precipitation. The opposite occurs in the winter since the land has already cooled since summer and the oceans discharge heat into the air above them.

During the monsoon season, India’s climate is hot and muggy, similar to that of South and Southeast Asia. Two of the four seasons that exist in the Indian subcontinent are monsoon seasons. Those are Season of the Southwest Monsoon and The Monsoon Season in the North-East.
The Arabic term mausin or the Malayan word monsin, both of which indicate season, are the origins of the name monsoon. Seasonal winds (rhythmic wind movements) (periodic winds) that change direction with the seasons are known as monsoons. A seasonal wind pattern known as the monsoon moves from the sea to land in the summer and from the land to the sea in the winter. According to some academics, monsoon winds are significant land and sea breezes.
Inter-Tropical Convergence Zone (ITCZ) is one of the important facts to understand the mechanism of the monsoons.
