Question

from where does the south west monsoon winds pick up humidity?

Answer 1

Monsoon is traditionally defined as a seasonal reversing wind accompanied by corresponding changes in precipitation, but is now used to describe seasonal changes in atmospheric circulation and precipitation associated with the asymmetric heating of land and sea. it comes from the big seasonal winds blowing from the Bay of Bengal and the Arabian Sea in the southwest bringing heavy rainfall to the area.

Answer 2

At the time of summer, a powerful low pressure develops over interior Asia as well as over North Western Asia. On the other hand, high pressure develops over the Southern Indian Ocean. Due to this, the movement of air takes place over the ocean in South Westerly direction, which crosses the equator and turns right towards the low-pressure regions over the Indian subcontinent. These are the South West monsoon winds, which blow from the sea to land and carry ample amount of moisture that brings rain.
