Who knows the climate situation on the day of the "White Dew" of the 24 solar terms and the situation after that?

Millennium is the first solar term in September. Dew is water droplets formed by condensation of water vapor on the ground or near-earth objects due to temperature drop. So the Millennium actually indicates that the weather is getting cold. At this time, people will obviously feel that the hot summer has passed and the cool autumn has arrived. Because the temperature is still more than 30 degrees during the day, but it drops to more than 20 degrees at night, and the temperature difference between them is 10 degrees. Yang Qi reached its peak in the summer solstice, and these two extremes must be reversed, and Yin Qi also rose at this time. When it comes to the White Dew, the yin gradually increases, and the morning dew gradually thickens and condenses into a layer of white water drops, so it is called the White Dew.
