Do you think it is right that ancient Chinese characters once recorded the frost on L Road?

It rains in Yun Teng, and the dew becomes frost. It means: Yun Sheng goes to the sky, and when it is cold, it forms rain; Dew quickly condenses into frost on a cold night.

Modern science and technology have proved that our earth absorbs heat after the sun comes out during the day and dissipates heat after the sun goes down at night. The earth's atmosphere is hot. When scattering upwards, due to the gradual decrease of surface temperature, water vapor turns into dew when it is cold. When the temperature drops further at night, it becomes frost, especially in the Millennium and the first frost solar terms, it becomes frost completely. In ancient times, only two sentences explained the causes of natural phenomena such as sex, rain and frost.

From a scientific point of view, the statement that "dew becomes frost" is not accurate. The frozen dew formed by dew freezing is hard small ice beads. Frost refers to the phenomenon of crop freezing injury caused by sudden drop of temperature. To form frost, the temperature of the ground or ground objects must drop below 0℃, and the water vapor content in the ground air should reach a certain level.

Therefore, there may not be frost in first frost, and there may not be frost in first frost. However, due to the low temperature when frosting, if the temperature continues to drop, it will easily lead to frosting.
