The main reasons for the formation of mountain climate in Qinghai-Tibet Plateau are as follows

The Qinghai-Tibet Plateau is located in the middle latitude. Because of the high altitude and low temperature all the year round (the temperature drops by about 0.6 degrees Celsius every time the altitude rises 100 meters), the plateau and mountain climate is formed.

The plateau and mountain climate has two most important characteristics: "high terrain (altitude)" and "low temperature (cold)". The vertical distribution of climate and biodiversity is a very special climate type. Other climates are mainly influenced by latitude, and the plateau and mountain climate is mainly influenced by topography, especially altitude. The daily temperature difference between plateau and mountain climate shall not exceed 10 degrees. There is frost and snowfall in winter, and there are many hot thunderstorms in summer. There is a lot of hail when it rains. Hot thunderstorms in summer on high mountains are mostly in the afternoon.
