Abstract
About 2×109 people live around the Tibetan Plateau and receive much water supply from the snowfall and rainfall over these mountains. Wet monsoon current make continuous and heavy rainfall on the southern side of Tibetan Plateau due to the orographic effect. Sometimes, Indian and Pakistan people are suffered from disastrous floods by these rainfalls. In the upper portion of the Himalayas, monsoon current make much snowfall in the warmer season by the monsoon. The glaciers and snowfields in the Himalayas are thus developed in summer. In the other hand, the snow and ice near the peak of these mountains are melting and supplying water to the rivers in summer.
North-western part of the Tibetan Plateau has not so much precipitation in summer, but relatively much snowfall in winter. In this region, water resource is mainly stocked in winter and supply the melting water to the deserts mainly in summer.
In this paper, several data are collected mainly from the mountaineering reports, and the mechanism of the water supply around the Tibetan Plateau are discussed.
