What is the relationship between altitude and temperature?

Many students want to know what is the relationship between altitude and temperature. I sorted out the relevant information, hoping to help everyone!

What is the relationship between the altitude of 1 and the temperature? At standard atmospheric pressure, the temperature drops by 6℃ for every elevation increase of 1km, and the troposphere temperature decreases with the elevation increase, because the main direct heat source of troposphere atmosphere is the ground, and the farther away from the ground, the less ground radiation is obtained.

Altitude refers to the vertical distance above or below the sea level of a certain place or geographical thing on the ground, which is the abbreviation of altitude. For example, the higher the altitude, the thinner the air and the lower the air pressure, and the boiling point of water in this place decreases.

1 Why the higher the altitude, the lower the temperature. 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.

In popular words:

The temperature change we feel is not directly from the heat of the sun, but from the air above the earth. The earth absorbs the heat from the sun and radiates it into the surrounding air. Therefore, the air is getting warmer from bottom to top. Therefore, the higher the mountain, the less heat in the atmosphere and the lower the natural temperature; In addition, the higher the mountain is, the thinner the air is and the less heat is saved. Therefore, when we climb mountains near the sun, we feel not too hot, but too cold.

1 What are the factors that affect the temperature 1? Latitude (decisive factor): it affects the height of the sun, the length of a day, the amount of solar radiation, and the daily temperature difference within the annual interval (the number of temperature days in low latitudes and annual intervals is smaller than that in high latitudes).

2. Topography (height, topography): shady slopes, sunny slopes, mountains, plains, river valleys and basins at different altitudes (for example, the topographic heat in river valley basins is not easy to dissipate, and the tall terrain blocks the winter wind, and the daily amplitude of mountain areas at the same latitude is worse than that in the plains, and the annual amplitude is smaller).

3. Location of land and sea: the annual variation range of temperature caused by ocean intensity.

4. Ocean current (warm current: warming and humidifying; Cold current: cooling and dehumidification)

5. Weather conditions (in cloudy and rainy places, the temperature changes daily, and the annual change range is smaller than that in cloudy and rainy places).

6. Underlying surface: ground reflectivity (high snow reflectivity and low temperature); The daily temperature and annual range of green land are less than that of bare land.

7. Human activities: heat island effect, greenhouse effect, etc
