How much does the temperature drop for every 1000 meters of rise?

The temperature drops by 4-6°C for every 1000 meters of rise. Due to the influence of landforms, biology, etc., the vertical change of mountain temperature generally decreases by about 0.4-0.6°C for every 100 meters of rise, that is, an altitude of 600-1200 meters. The temperature here is 3-6℃ lower than that in the plains.

Troposphere: The temperature decreases with altitude, decreasing by 0.6°C for every 100 meters of altitude. The convective movement is significant (low latitude 17-18, mid-latitude 10-12, high latitude 8-9 kilometers), and the weather phenomena are complex and changeable. Reason: Most of the heat comes from the upper and lower parts of the ground. The difference is large, the convection is strong, there are many water vapor impurities, and the convection movement is significant.

Stratosphere: At first, the temperature changes little, and the temperature rises rapidly above 30 kilometers. The atmosphere mainly moves horizontally. Smooth atmosphere and clear weather are conducive to high-altitude flying. Reason: Ozone absorbs ultraviolet light. Hot at the top and cold at the bottom. Water vapor has less impurities and moves horizontally.

Upper atmosphere: There are several ionized layers that can reflect radio waves and play an important role in radio communications. (Divided into three layers from bottom to top): middle layer, warm layer (ionized layer), escape layer Reason: the action of solar ultraviolet rays and cosmic rays.
