As the saying goes, "indulge in the white dew and slip away every day." Is there a scientific basis for "rotten white dew"?

"Rotten white dew" has no scientific basis. Although the Millennium season means the real arrival of autumn, whether it rains or not actually depends on the relevant principles of meteorology, so this statement is unreliable.

The Book of Songs says, "White dew is frost." . After the white dew, the dew turned into frost, indicating that autumn has really come from now on. The night is cool, the temperature difference between morning and evening is getting bigger and bigger, and the climate difference between north and south is becoming more and more obvious. The dew in the north condenses into frost, which is colder, but relatively dry, but there will be drought most of the time; The south is relatively warm and humid, and the water content is much higher than that in the north, but the precipitation may increase. So whether it will rain or shine every day after the Millennium cannot be summarized in one sentence. It is closely related to regional environment, meteorology and other reasons.

Rain is a thousand years ago, ghosts are a thousand years later. In order to get a better harvest, hardworking farmers seem to pay more attention to the weather after the Millennium. In ancient times, people thought that it usually rained on the day of the Millennium, and it probably continued to rain all autumn. Because ancient farmers lived by the weather, they hated the rain in the Millennium. They think that if it rains that day, it will be very unlucky, and autumn will no longer be the harvest season, which will affect their crops. For the sake of the family's livelihood, farmers who believe in ghosts and gods even pray that it will not rain in the Millennium, or they will starve to death and freeze to death for a year.

Agricultural proverbs are generally summarized according to the experience of predecessors, but there is still no scientific basis for "rotten white dew" The weather forecast is still based on the real-time water content of clouds and other reasons. The weather in the whole autumn cannot be determined by the weather of the white dew on that day, so the saying of "rotten white dew" is only empirical and for reference only.
