What is the weather like in Tibet? Is it hot in summer?

Every cubic meter of air in Tibet Plateau contains only150-170g of oxygen, which is the lowest temperature in summer. Especially in northern Tibet, the temperature is below 8 degrees Celsius in summer and July.

Judging from the temperature difference, the characteristics of small annual temperature difference and large daily temperature difference in Tibet are particularly obvious. The annual temperature difference between Lhasa, Qamdo and Shigatse is 18-20 degrees Celsius, while Wuhan and Nanjing with similar latitudes are 26 degrees Celsius. The annual average daily range of Lhasa, Qamdo and Shigatse is 14- 16 degrees Celsius, while that of Chengdu, Changsha and Nanchang is only 7 degrees Celsius. The diurnal range of heliostats is 18.2 degrees Celsius, which is about 2.5 times that of Nanchang at the same latitude.

In places above 5000 meters above sea level in Ali area, the daytime temperature can reach 10 degrees Celsius in summer and August, and the nighttime temperature drops below zero degrees Celsius. Lhasa and Shigatse, located in the Yarlung Zangbo River basin, have the highest temperature of 27-29 degrees Celsius at noon in June, giving people the feeling of midsummer. The temperature drops in the evening and the air is crisp in autumn; At midnight, the temperature drops to 5 degrees Celsius, and the quilt should be covered all night; After sunrise in Rosty Yi, the temperature rises, giving people a feeling of spring. It's really "cold clothes are prepared all year round".

According to the distribution of climate types, the areas below 1 100 meters above sea level in southeastern Tibet and the southern slope of Himalayas belong to tropical mountain monsoon humid climate. The average temperature in the warmest month here is above 22 degrees Celsius, and the average temperature in Leng Yue is below 13 degrees Celsius, which is higher than that in eastern China at the same latitude.

The annual precipitation is 2,500 mm, reaching 4,495 mm in some places, which is the most rainy area in Tibet and one of the rainy areas in China. Here, the trees are lush, the seasons are evergreen, all kinds of tropical plants grow luxuriantly, vines are entangled, and the wild banana, wild lemon forest and bamboo forest all over the mountains constitute a beautiful tropical scenery. Tropical cash crops can be planted here and harvested three times a year.

The Yarlung Zangbo River basin, north of Himalayas, south of Gangdise Mountain and Nyainqentanglha Mountain, is 500-4200m above sea level, and belongs to the semi-humid and semi-arid climate of plateau temperate monsoon. The average temperature in the warmest month is 10- 18 degrees Celsius, and the annual precipitation is 400-800 mm. It can be used to grow cool crops such as wheat, highland barley and potato and temperate fruit trees, and the crops can be harvested once a year.

The lake basin area in the south of northern Tibet Plateau, north of Gangdise Mountain-Nyainqentanglha Mountain, is 4200-4700 meters above sea level, and belongs to the semi-arid and arid monsoon climate in the plateau sub-cold zone. The average temperature in the warmest month is 6- 10 degrees Celsius, and the annual precipitation is100-300mm. It is a prairie in Tibet, with animal husbandry as its main industry.

The plateau in northern Tibet is 4700-5500 meters above sea level, which belongs to the monsoon dry climate in the cold region of the plateau. The average temperature in the warmest month is below 6 degrees Celsius, and the annual precipitation is100-150 mm. This is a vast natural pasture. The area above 5500 meters above sea level is covered with snow all year round, which is a world of ice and snow with crystal clear as pearls and broken jade.
