Solution
The Himalayas play a very significant role in influencing the climate of South Asia by virtue of their high altitude, length and direction. They effectively intercept the summer monsoons coming from Bay of Bengal and Arabian Sea and cause precipitation in the form of rain or snow. Besides, they prevent the cold continental air masses of Central Asia from entering into India.
