Due to the high altitude, the air on the Qinghai-Tibet Plateau is relatively dry and thin, the solar radiation is relatively strong, and the temperature is relatively low. Due to its complex and changeable terrain, the climate itself on the Qinghai-Tibet Plateau also varies greatly from region to region. Generally speaking, there is less rainfall on the plateau. The Tibetan Plateau itself is also an important factor affecting the earth's climate.
According to paleontological and geological investigations, the uplift of the Tibetan Plateau caused huge changes in the global climate. As a tall wind screen, it effectively blocks the cold air from the northern continent from entering South Asia. At the same time, the Himalayas block the warm and humid air from the south from moving northward, and are an important factor in causing the rainy season in South Asia.
In summer, the plateau is heated significantly, forming an anticyclone at high altitude - the Tibetan High, which greatly strengthens the intensity of the South Asian monsoon and can affect the location and intensity of the subtropical high.
In winter, due to the cooling of the plateau ground, the temperature of the surrounding atmosphere is higher. The plateau absorbs heat from the surrounding air, forming a low-temperature downdraft. The cold air on the plateau sinks to nearby areas. Part of the cold air sinking from the Tibetan Plateau will flow to Mongolia, greatly strengthening the intensity of surface high pressure in Mongolia and forming another cold high pressure center in winter - the Mongolian High.
The Qinghai-Tibet Plateau has a vast territory, a long and complex geological history, and rich materials formed in various environments. Among the more than 100 mineral resources that have been discovered, nearly 70 have proven partial reserves, among which chromium, copper, lead, zinc, crystal, asbestos, salt lake, and hydrothermal mineral reserves are relatively large; silver, gold, tin, and platinum have large reserves. Mineral reserves of group elements and rare earth elements are also considerable.
The copper deposits on the Qinghai-Tibet Plateau are widely distributed, with large scale and reserves. There are many types of deposits and associated minerals, which are often composite types with lead, zinc, diamond, silver and other minerals. Polymetallic deposits. The most typical copper mine is the Yulong Copper Mine in eastern Tibet, with preliminary proven copper metal resource reserves of 6.5 million tons.

Topography
There are many mountains around the Qinghai-Tibet Plateau. Most of them run from northwest to southeast. Compared with the mountains outside the plateau, The ground rises steeply and rises a lot. Many of the peaks in the southern Himalayas are among the top ten in the world, especially Mount Everest, the highest mountain in the world.
At the same time, in addition to the plains, there are many mountain peaks within the plateau, with huge differences in height. There are also many glaciers, mountain lakes and alpine swamps on the plateau. The major rivers in Asia (Yellow River, Yangtze River, Lancang River, Nu River, Brahmaputra River, Ganges River, Indus River) all originate here.
