What is the meaning of an autumn rain and a cold? After the beginning of autumn, is the air filled with a trace of cool? Then, after the autumn rain, the temperature is naturally reduced, so we should do a good job in keeping warm.
In autumn, a stream of cold air from Siberia and Mongolia flows south into most parts of China. When it meets the declining warm and humid air in the south, rain forms.
One time cold air southward, often causes one time rainfall, and causes the local temperature to reduce one time.
In addition, at this time, the direct sunlight gradually moves to the south, reducing the light and heat in the northern hemisphere day by day, which is also conducive to the enhancement of cold air and southward.
After several times of cold air going south, the local temperature is very low. This is the principle of "one autumn rain and one cold".
When does an autumn rain and a cold start
The saying of "one autumn rain and one cold" is mainly applicable to the Mid Autumn period. The saying that "ten autumn rains need to wear cotton" means that there is gradual cooling, and the word "cold" is certainly different from "cool". Some people call "cold dew Festival" in the subtropical region as a turning point from cold to cold, which seems to be earlier. It is more accurate to say "frost fall festival". Because the twenty-four solar terms of White Dew, cold dew and frost fall reflect the influence of water vapor condensation and cooling on the ground. Frost fall means frosting, which mainly refers to the Yellow River Basin. In the middle subtropical zone, even in the north subtropical zone, the average time of frost period at the beginning of each year is to the end of November, and rarely to the end of October. Since then, the cold air has gone south again, making the transition from late autumn to winter.
