This article was reviewed by Zhang Feng, meteorological engineer at the National Meteorological Center These past few days It's rainy in many places After the rain Although the sky cleared But I still feel that the weather is getting colder I often hear elders say "An autumn rain brings a chill" Actually, think about it carefully Since the beginning of autumn It's true So "An autumn rain brings a chill" Is there any scientific basis for this? Come and see turn out to be There is a saying that “an autumn rain brings a chill” Because: First After entering autumn A cold front moving south from Siberia and Mongolia Encountered warm and humid air from the south It forms rainfall No matter how high the local temperature is, it cannot withstand the frequent rainfall. Second After the Autumnal Equinox The sun's direct point slowly moves southward In this way The angle of sunlight in the Northern Hemisphere will also continue to tilt The heat gained by the ground gradually decreases In addition, the ground itself radiates and cools The temperature on the ground will get lower and lower besides It also depends on latitude The higher the latitude, the more cold air there is. As it goes south again and again The rainfall also increased Do you all understand? The weather will gradually get colder Friends, please add clothes at any time. Be careful not to catch a cold! |
