How is the Indian monsoon formed?
India receives south-west monsoon winds in summer and north-east monsoon winds in winter. South-west monsoons are formed due to intense low pressure system formed over the Tibetan plateau. North-east monsoons are associated with high pressure cells over Tibetan and Siberian plateaus.
