Explanation

Ladakh Cold Desert: Situated in the Trans-Himalayan region at an elevation ranging from 3,000 to over 6,000 meters above sea level, Ladakh is widely known as the cold desert of India.
-
Rain Shadow Effect: It lies in the rain shadow of the Great Himalayas, which blocks the moisture-laden Southwest Monsoon winds. As a result, the region receives extremely low annual rainfall (less than 10 cm per year).
-
Climate & Features: Characterized by extreme cold winters, freezing winds, low humidity, arid gravelly terrain, high solar radiation, and sparse vegetation.
