Characteristics of summer temperature distribution in southern Xizang Autonomous Region and its influencing factors

Tibet, with an average elevation of about 4,000 meters, is known as the "roof of the world". Due to the complex terrain, solar radiation and high-altitude atmospheric circulation, a plateau climate with low temperature, dryness, lack of oxygen, windy, great vertical variation and obvious regional differences has been formed.

Climatic characteristics of Tibet:

1, Tibet Plateau is in the middle and low latitudes, with long sunshine hours, and because of high altitude, thin air, strong ultraviolet rays, less water vapor and partial cloudy weather, the light energy resources rank first in the country.

2. The annual temperature is low, the temperature difference between morning and evening is large, and the annual difference is small.

3. The precipitation is small and unevenly distributed, and the annual precipitation gradually decreases from southeast to northwest.

4. Climate types are diverse, with obvious vertical changes. The vertical band spectrum of climate decreases from southeast to northwest, and there is a scene of "one mountain with four seasons and ten miles of different days".

The following is the annual temperature distribution table of some important towns:

The climate in Tibet

Climate of Spring and Summer in Tibet (May to 65438+ 10) dressing index:

In Lhasa, Linzhi, Shigatse and other places below 4,000 meters above sea level, you can wear coats during the day, and it is not recommended to wear shorts, because the ultraviolet rays here are strong and easy to get sunburned. You should take good sun protection measures, keep warm and prevent colds. In high altitude areas such as Ali and Naqu, the temperature is low in the morning and evening, so you should bring down jackets, sweaters and other warm clothes.
