The frosty season is characterized by colder weather in the morning and evening, hotter weather at noon, a big difference in temperature between day and night, and obvious autumn dryness. The relevant explanations are as follows:

1. Cold weather in the morning and evening: During the Frost Festival, the weather in the morning and evening becomes colder due to the gradual decrease in temperature. This is due to the gradual decrease in the angle of direct sunlight, the solar radiation energy received during the day gradually decreases, while more energy is dissipated at night. As a result, the temperature difference between morning and evening is greater and the temperature gradually drops.

2, hotter at noon: Although the weather is colder in the morning and evening of the Frost Festival, the temperature is relatively high at noon, and sometimes even feels hotter. This is because during the frosty season, the sun's angle of direct sunlight gradually decreases, but at noon the sun's altitude angle is larger, the sun shines directly on the ground, the ground receives more solar radiation energy, so the temperature at noon is relatively high.

3, day and night temperature difference: during the frosty season, due to the gradual decrease in temperature, the temperature difference between day and night is greater. This is because during the frosty season, the solar radiation energy received during the day is less, while the night is more energy dissipation, so the temperature difference between day and night is larger. This is one of the characteristics of the frosty season.

4, autumn dryness is obvious: after the frost festival, the late autumn scene is becoming more and more obvious, the air humidity gradually reduced, the climate becomes dry, easy to appear dry skin, dry mouth, cough and other symptoms. This is due to the reduction of moisture in the air, humidity decreases, resulting in faster water loss in the human body, prone to dry symptoms. Pay attention to maintaining indoor humidity during the frosty season and drink more water to keep your skin moist.
