Factors Affecting Indian Monsoon

Major Factors that Affect Indian Monsoon

Himalayan Barrier

• The Himalayas block the cold and dry air masses coming from Central Asia during the summer monsoon season.
• This barrier forces the warm and moist air from the Indian Ocean to ascend, cool, and release heavy rainfall over the subcontinent.
• The Himalayas create an orographic effect, causing increased rainfall on the windward side (northern slopes) and a rain shadow region on the leeward side.
• This uplift of moist air contributes to the formation of the South Asian monsoon trough, a low-pressure region responsible for the onset and intensity of the monsoon.
