Whenever the surface level pressure is high over the Pacific Ocean and low over Indian Ocean, the south west monsoons in India tend to be stronger.

(ii) Northern Mountain Ranges: The Himalayas and the adjoining mountain ranges protects India from the bitter cold dry winds of Central Asia during winters. The mountains also act as an effective physical barrier for the rain bearing southwest monsoons to cross the northern frontiers of India.
