Is it sunny or cloudy at noon, and at night!

Sunny day, high temperature at noon. Because the earth absorbs heat in the morning, the heat absorbed by specific heat capacity begins to radiate like air when it arrives, so the temperature in the air is the highest at noon, reaching an exothermic state. In the afternoon, as the sun goes away, the heat decreases, and the temperature will gradually drop, and the night is not as hot as noon. On cloudy days, the sun's heat is blocked by clouds, so the heat exchange is reduced and the temperature is naturally low. But you will be bored because of the air pressure. It's warmer on cloudy days at night, because the clouds emit heat, so it won't be particularly cold at night, especially the temperature difference between morning and evening is not big.
