The primary cause of monsoons is the difference between annual temperature trends over land and sea . ... This low pressure regions sees continuous rise of moist wind from the sea surface to the upper layers of the atmosphere, where the cooling means the air can no longer hold so much moisture resulting in precipitation.

Following facts are important in formation of monsoon: The Sun causes differential heating and cooling of land and water . This creates low pressure on the landmass of India and high pressure over the ocean surface. ... This results in strong vertical air currents and formation of high pressure over the plateau.
What is the major cause of monsoon?
The primary cause of monsoons is the difference between annual temperature trends over land and sea . The apparent position of the Sun with reference to the Earth oscillates from the Tropic of Cancer to the Tropic of Capricorn. Thus the low pressure region created by solar heating also changes latitude.
