Answer 1

This causes a complete reversal of the direction of winds during summer. Air moves from the high pressure area over the southern Indian ocean in a south-westerly direction, crosses the equator and turns right towards the low pressure area over the Indian sub-continent. These winds are known as south-west monsoon winds.
