So the summers we gather all the low possible pressure here and at its end, we welcome winds of monsoon. Atleast that is my understanding.
The stronger a light shines the darker are the shadows around it.
The wind which starts blowing from sea to land takes water vapour (clouds) to the land and the clouds are trapped not able to go across Himalayas and start precipitating in Indian peninsula only.
This is the general scenario at the time of monsoon. There are rare instances where due to geographical reasons this pattern does not repeat in a particular year and we have drought situation.
Thoughts exchanged is knowledge gained.
