The climate features strong radiation, abundant sunshine, less accumulated temperature, and the temperature decreases with the increase of the altitude and latitude. According to calculations, the average annual temperature decreases by 0.57°C for every 100 meters of altitude increase, and the annual average temperature decreases by 0.63°C for every 1-degree increase in latitude. Winter is dry and cold with strong wind; Summer is cool and rainy with hail sometimes. In a word, the four seasons are not easy to distinguish. The average temperature of the warmest month in most areas is below 15℃, and the average temperature in January and July is 15-20℃ lower than that of the eastern plain at the same latitude. According to climate classification, except for the valley area in the southeastern margin, the whole of Tibet has no summer throughout the year. The annual total radiation value is as high as 5850-7950 MJ/m2, which is 0.5-1 times higher than the eastern plain at the same latitude.
The living habits of the people thriving on the Tibetan Plateau are summarized in short: the clothing is mainly Tibetan robes. Men wear trousers and women wear long skirts. The main food is Zanba, butter tea, beef, and mutton. And the Tibetan people in pastoral areas live in tents, while tibet women in rural areas live in 2 or 3 stories blockhouses, or wooden and stone single-story houses.
