The mechanism of Indian Monsoons:- 

(i) The different 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. It fixes the direction of the moisture-laden wind from sea to land. 

(ii) The shift of the position of Inter Tropical Convergence Zone (ITCZ): In summer, low-pressure trough is positioned over the Ganga plain, making the region suitable for the occurrence of rain. 

(iii) The intensity and position of the high atmospheric pressure over the Indian Ocean affect the Indian monsoon. 

(iv) 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 9km above the sea level. 

(v) The movements 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 the summer affects monsoon.
