Question
Why maximum rainfall in India occurs after the summer season?
Solution
- The large landmass to the north of the Indian Ocean gets intensely heated during April and May. This causes the formation of intense low pressure in the north-western part of the Indian subcontinent.
- Since pressure in the ocean to the south of the landmass is high, it attracts the south-east trade winds, which prevail in the southern hemisphere.
- These S.E. Trade winds, after crossing the equator, are deflected towards the right and reach the west coast as the south-west monsoon. These winds bring heavy rainfall accompanied by thunder and lightning.
