Himalayas, the barrier of the North are an integral part of Indian geography. It is also an important influencing factor in the climatic conditions of India. Some of its impacts are:

1. Barrier to Air Masses: The Himalayas act as a barrier to the winds due to their formidable height and large size. They obstruct southward moving cold winds from Central Asia from entering the Indian subcontinent. This plays a vital role in the moderation of temperature in India.

2. Monsoon Patterns: During the summer monsoon, the Himalayas lift moist winds from the Indian Ocean causing cooling and condensation, leading to heavy rainfall on the windward side. On the leeward side of the Himalayas, the air loses moisture leading to arid conditions.

3. Glacial Meltwater: The Himalayas are home to numerous glaciers and snowfields. This acts as a source of freshwater for the majority of the river systems in India. Seasonal melting of the snow and ice aids the river flow.

4. Impact on Local Weather: The mountains contribute to diverse local weather patterns. For instance, the Kumaon and Garhwal regions experience different climatic conditions compared to the plains due to their altitude and proximity to the Himalayas.

Therefore, the fact that the Himalayas are important in deciding the climatic controls of the Indian continent make them an important part of the geography of India. Climate change and pollution on the mountains expose the Himalayas to imminent threat in as far as its climate regulatory duties are concerned. Consequently the following message is needed: the people must be informed that the mountains have to be clean for people to have a safe future.
