1. Climatic Influence

The impact of the Himalayas on the climate, especially on distribution of precipitation and temperature, is quite significant. The altitude of the Himalayas, their sprawl and extension intercept the summer monsoon coming from the Bay of Bengal and the Arabian Sea. They also prevent the cold Siberian air masses from entering into India. Had there been no Himalayas, the whole of northern India would have been a desert. According to the latest meteorological studies, the Himalayas are responsible for the splitting of the jet streams into two branches, and these in turn, play an important role in the arrival, success and failure of the monsoons in India.
