What clothes to wear in Tibet 10?

Tibet may wear short suits, T-shirts, thin jeans and trousers, leisure suit, professional suits and other clothes and trousers during the day, and coats, long coats, jackets, sweaters, woolen suits, suits, mountaineering clothes and other warm clothes and trousers at night.

1. It rains many nights in Tibet.

Even if you travel to Tibet in the rainy season, you will never get wet without rain gear during the day. Be careful when going out at night. Night rain is a feature of Tibet's climate. The rainy season in Tibet began in April and May in Chayu and Medog in southeast Tibet, and the rainfall center moved westward. Gradually expand to the hinterland areas such as Lhasa and Shigatse, and the rainy season will enter the whole territory of Tibet in July, and the rainy season will soon end from mid-late September to early June 10.

The night rain rate (that is, the precipitation from 8: 00 p.m. to 8: 00 a.m. the next day, accounting for the percentage of 24-hour precipitation) in all parts of Tibet is mostly above 60%, especially in the Yarlung Zangbo River basin, where the annual night rain rate is 85% in Lhasa and 82% in Shigatse. Only the southeast of Tibet and the Himalayas have less night rain, accounting for about 50%.

Second, the formation conditions of night rain in Tibet.

Besides the large-scale weather situation, the formation of nocturnal rain in Tibet is mainly influenced by local topographic conditions. During the day, the solar radiation heating area on the hillside is large and the temperature rises rapidly, forming a low-pressure area, while the heating area in the valley is small and the temperature rises slowly, forming a high-pressure area, and the airflow rises from the valley to form a valley wind, forming a cumulus cloud with a convex top and a flat bottom in the air, which is shaped like steamed bread.

However, during the day, the solar radiation is strong, and the water droplets in the clouds are easy to absorb heat, evaporate and dissipate, so the clouds become thinner, and even the sky is partly cloudy or clear and Wan Li. When the sun goes down, the ground cools down quickly, and the hillside cools down quickly. The cold air sinks and lifts the warm air in the valley, which increases the atmospheric disturbance and provides conditions for rainfall.

Coupled with the cooling of the cloud top at night, the warmth of the lower layer, the strengthening of convection and the increase of instability in the cloud are conducive to the saturation and condensation of water vapor, which eventually forms night rain.

Thirdly, the overall characteristics of temperature in Tibet are analyzed.

1, the daily range of annual average temperature in Lhasa, Shigatse and Qamdo is 14~ 16 degrees. Ali area is more than 5000 meters above sea level. In summer and August, the daytime temperature can reach above 10 degrees, and the nighttime temperature drops below zero, and streams and pools freeze.

2, all the year round, be prepared for the cold winter all the year round. Every June, the highest temperature in Lhasa and Shigatse at noon can reach 27~29 degrees, giving people the feeling of midsummer. When the temperature drops at night, people will feel cool in autumn. In the middle of the night, the temperature drops to 0~5 degrees, and the quilt should be covered all night, just like in winter. After sunrise in Rosty Yi, the temperature rises again, just like in spring.

In order to adapt to this special climate of "preparing for the cold winter all the year round", Tibetans take off their sleeves during the day when there is plenty of sunshine, adjust their body temperature, and then wrap their Tibetan robes tightly at sunset.

3. Most parts of Tibet have high altitude and large temperature difference between day and night. In winter and early spring, the climate is dry and cold, the wind and sand are heavy, the oxygen content in the air is obviously lower than that in summer, and many areas and road sections are covered with snow and ice. So April -65438+ 10 is the ideal time to travel to Tibet. July-August is the rainy season in Tibet, and there will be mudslides, landslides and swamps. In some sections, this will make it impossible for vehicles to pass.
