How many degrees does the temperature drop per altitude 1000 meters?

Every altitude 1000 meters, the temperature will drop by 6℃.

The influence of topography on climate is mainly manifested in the decrease of temperature with the increase of topography. Generally speaking, the temperature drops by about 0.6℃ every time the altitude rises 1000 m, and it drops by about 6℃ every time the altitude rises1000 m, which is the main reason why "one mountain has four seasons" and some snow on the top of the mountain does not melt all year round.

Details are as follows:

At high altitude, there are few clouds, and the inverse radiation to the ground at night is weak and the temperature is low. Because of the high altitude, less ground radiation is absorbed during the day, because the temperature decreases with the elevation. 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.

More information is as follows:

Every altitude 1000 meters, the temperature drops by about 6.5℃. Due to the influence of topography, biology and other factors, the temperature in alpine areas generally drops by about 0.4-0.6℃ for every increase of 100 m, that is, the temperature at 600- 1200 m above sea level is 3-6℃ lower than that in plain areas.

This is the variation law of the adiabatic temperature in the troposphere, and the average temperature drops by 0.6℃ for every rise 100 meter. Temperature is actually the result of the impact of molecular motion, and molecular motion is also the cause of air pressure.

With the elevation, the density of air molecules decreases. For molecules with the same motion state (speed), the statistical effect of impact will be weakened, so people will feel "temperature drop" In extreme cases, when the altitude is above the atmosphere and there are almost no air molecules, the temperature will be close to absolute 0 degrees.

As follows:

From the actual situation, people living in low-altitude areas generally feel normal below 2400 meters above sea level and have no obvious reaction; Above 2400 meters, if there are reasonable height steps and enough time, you can still adapt gradually; After more than 5500 meters, no matter how much time it takes, you can't fully adapt.
