Ladakh is a high altitude desert as the Himalayas create a rain shadow, denying entry to monsoon clouds. The main source of water is the winter snowfall on the mountains. Recent flooding in the region (e.g., the 2010 floods) has been attributed to abnormal rain patterns and retreating glaciers, both of which might be linked to global warming. The Leh Nutrition Project, headed by Chewang Norphel, also known as the 'Glacier Man', currently creates artificial glaciers as one solution for retreating glaciers.
The regions on the north flank of the Himalayas — Dras, the Suru valley and Zangskar — experience heavy snowfall and remain cut off from the rest of the region for several months in the year, as the whole region remains cut off by road from the rest of the country. Summers are short, though they are long enough to grow crops. The summer weather is dry and pleasant. Temperature ranges are from 3 to 35 °C in summer and minimums range from -20 to -35 °C in winter
