Correct: "The clouds turn into rain, and the dew turns into frost" is an image of the ancients' understanding of the three-state changes of water.
Under normal circumstances, the quality of cold air is higher than that of hot air, which is also the principle of hot air balloons and sky lanterns. When the water on the earth is heated, it turns into water vapor and evaporates into the air. The water vapor is cooled in the high altitude and turns into small water droplets. The small water droplets are small and light and are held up by the rising airflow in the air and slowly join together to form. Clouds, when the cloud layer becomes thicker and the air is not enough to hold it up, the water droplets inside will turn into rain and fall to form precipitation. If the weather is cold during the falling process, they will turn into snowflakes. There are also other forms of precipitation such as hail.
Due to the temperature difference between day and night, water vapor in the air will turn into dew and condense on the surface of objects such as plants, trees, stones, etc. at night. If the temperature at night is below zero, then the water vapor in the air will directly condense on the surface of the object. Ice that condenses into solid form is frost.
Original text: The clouds turn into rain, and the dew turns into frost.
Translation: The rising clouds form rain when they become cold, and the dew turns into hoarfrost when it becomes cold at night.
These two sentences explain the formation of the natural phenomenon of clouds, rain, frost and dew, "the earth's atmosphere rises into clouds, and the weather falls into rain." Frost and dew are the same thing, except that dew is liquid and frost is solid. Our earth absorbs heat after the sun rises during the day and dissipates heat after sunset at night. The earth's atmosphere is hot. When it disperses upward, the surface temperature gradually decreases, and the water vapor turns into dew when it cools. When the temperature drops further at night, it will form frost. Especially during the white dew and frost seasons, it will completely turn into white frost.
"The clouds cause rain" comes from "Suwen Yin and Yang Ying Xiang Da Lun" which says: "The earth's atmosphere is clouds" and "Book of Rites Yue Ling" says: "When the weather drops, the earth Angry."
"Dew condenses into frost" comes from the words "Kun Gua" in "Book of Changes", "When the frost reaches solid ice, the yin begins to condense." If you step on frost, you will think that the time of freezing ice is coming soon. The yin begins to condense, and the yin energy begins to condense.
