Less cloud cover in Lhasa weakens solar radiation, and high temperature is reasonable, isn't it? Why?

1 Because the air pressure is low, the air is thin. Poor atmospheric heat preservation at high altitude leads to a large amount of heat loss.

High altitude, less clouds, weak adverse radiation to the ground at night and low temperature.

Because of the high altitude, less ground radiation is absorbed during the day, because the higher the altitude, the lower the temperature.

The temperature of the atmosphere mainly comes from the long-wave radiation on the ground. At high altitude, the air is thin, and the ground absorbs less long-wave radiation during the day, so the temperature is low. At night, the atmosphere has poor thermal insulation and low temperature. So the higher the altitude, the lower the temperature. In the troposphere, the temperature drops by about 0.6 degrees for every elevation increase of 100 meters.
