Indian Monsoon:

1) South West Monsoon:

- 80% of rainfall we are getting from South West Monsoon.

-In summer land is getting heated and forms a heat low pressure in Indian Main lands.

--This in turn pulls the ocean current from Sea to land.

- Arabian Sea current from the South of Indian Ocean and Bay of Bengal current from the South of Andaman Sea flows in to the mainland.

-The Himalayas acts as barrier to these monsoon current and deflects it towards low pressure area causing South West Monsoon Rainfall(May - September)

2) NorthEast Monsoon:

-Same as SWM , Himalayas acts as a Barrier in protecting the heavy Cold current from Northern side.

-During (September - October) the landmass in the northern parts of India is cool so it forms high pressure.

-This high pressure pushes the cold current from the land to sea through Bay of Bengal and Southern States gets rainfall.
