When does the highest temperature usually appear in a day?
The sun shines on the ground to make it hot, and the heat absorbed by the ground is released to make the air hot, so it takes some time for the temperature to rise after the ground gets hot. After noon, when the heat released from the ground is still less than the heat provided by the sun, the ground temperature will not rise to the highest until two or three o'clock in the afternoon, and the temperature will be the highest.
Extended data
The main factor affecting the temperature is the intensity of solar radiation, and the light and heat of the sun can not directly raise the temperature. The heat energy directly absorbed by various gases in the air is only about 14%, while about 43% is absorbed by the ground.
After the ground absorbs solar radiation heat, it is conducted into the air through radiation, convection, turbulence and other forms. The result of this upward heat transfer is the main reason for the temperature increase. Therefore, the increase of ground temperature is mainly the result of absorbing solar radiation energy.
