Question

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

During summer, a powerful low pressure develops over interior Asia as well as over north western Asia. On the other hand, high pressure appears over the Southern Indian Ocean.

These are South West Monsoon winds.They blow from the sea to land and carry lots of moisture which brings rain.
