Question:
Discuss the mechanism of monsoons.

Answer:

Following are the factors responsible for the mechanism of monsoon:

(i) Sun causes the differential heating and cooling of land and water. This creates low pressure on India's landmass and high pressure over the oceanic surface.

(ii) The inter tropical convergence zone (ITCZ) is normally positioned approx 5 N of the equator. It shifts over the ganga plains during the summers which is also called as the monsoon trough during the season of monsoon.

(iii) The high pressure area, east of Madagascar is about 20 S over the indian ocean which affects the Indian monsoon.

(iv) The Tibetan plateau gets intensely heated during the summers which results in strong vertical air currents and formation of high pressure over the plateau. This high pressure zone is approx. 9 km above the sea level . The westerly jet stream moves to the north of the himalayas and the tropical easterly jet stream moves over the Indian peninsula during the summers.
