The climate of the Western Himalayas varies significantly with altitude and location. Lower elevations experience
temperate conditions, while higher altitudes are subject to
subarctic and alpine climates. Winters are long and harsh in the upper reaches, with heavy snowfall between November and March. In contrast, the foothills enjoy a relatively mild winter and warm summer. •
Western Disturbances, originating from the Mediterranean region, are the primary source of winter precipitation. These systems bring snow to the higher altitudes and rainfall to the valleys. • Summers are generally cooler than the adjacent plains, making hill stations like Shimla and Srinagar popular retreats. • Due to the
rain shadow effect caused by the Pir Panjal range, areas like
Ladakh and
Spiti Valley remain dry throughout the year, receiving less than 100 mm of precipitation annually. The climate plays a crucial role in shaping the region’s ecology, agriculture, and tourism patterns. == Geology ==
