Why does the temperature drop?

The decrease of temperature is caused by the decrease of thermal energy in the atmosphere or the change of its propagation mode. These factors include:

Earth rotation: The rotation of the earth will make a certain area out of direct sunlight and enter the shadow area, and the temperature in this area will drop.

Solar radiation: the intensity of solar radiation energy is an important factor affecting temperature. When the solar radiation energy is insufficient or the sun is far away from the earth, the temperature will drop.

Humidity: As the water vapor content in the air increases, the temperature will drop, because water vapor can absorb the heat in the air, thus reducing the heat energy in the atmosphere.

Ocean current: Ocean current can affect the temperature distribution, because the water temperature on the ocean surface will affect the air temperature, thus affecting the temperature distribution.

Terrain: Terrain also has a great influence on the temperature. For example, the temperature in high mountains is lower, because the higher the altitude, the lower the temperature.

In a word, the temperature drop is caused by many factors. On the basis of understanding these factors, we can better understand and predict the temperature change.
