The mechanism of monsoons :
(a) The different rates of heating and cooling of land and water : At the end of May, due to high temperature, low pressure is created on the landmass of India while seas around experience comparatively high pressure.
(b) The shift of the position of Inter Tropical Convergence Zone (ITCZ) : In summer, over the Ganga plain, low pressure trough is positioned.
(c) The presence of high pressure area at 20° South over the Indian ocean : The intensity and position of this high pressure area affects the Indian monsoon.
(d) The Tibetan Plateau gets intensely heated during summer which results in strong vertical air currents and formation of high pressure over the plateau at about 9 km above sea level.
(e) The movement of the westerly jet streams to the north of the Himalayas and the presence of the tropical easterly jet streams over the Indian Peninsula during summer. This periodic change in pressure conditions is known as the Southern Oscillation or "SO".

The relevant features in explaining the monsoon mechanism are as follows: The presence of abundant water bodies around the subcontinent: the Arabian Sea, Bay of Bengal, and Indian Ocean. ... The presence of abundant highlands like the Western Ghats and the Himalayas right across the path of the southwest monsoonwinds.
