How do the mountains along the northern borders affect the climate of south asia?

Mountains along the northern border, including the Himalayas affect the climate of south Asia by influencing their temperatures and humidity. Most of the Southern Asian countries like India experience a warm, humid climate. The height of the Himalayas concentrates most of the monsoonal winds on the Indian subcontinent as well as blocking cold winds from Siberia from reaching the region. As a result, most of India experiences a warm, tropical climate with more precipitation.
