Is it true that there is dew in the south during the cold dew season?

Literally, the "cold" of cold dew is cold, and "dew" represents the phenomenon that water vapor in the near-surface layer condenses into dew. However, from the meteorological point of view, the cold dew solar terms are the same as the white dew and the first frost, and the significance of its heat change is more obvious than its humidity change It should be said that it more embodies a process of temperature change and seasonal change.

Maybe friends in the south will have such a problem. Why didn't we see dew when it was cold? In fact, it is easy to understand, because the 24 solar terms come from the Yellow River Basin. At this time, the temperature in the south of the Yangtze River is still high, and the dew appears later than in the north.

The solar term from the cold dew to the back of the first frost is only a short 15 day, but it is a period of time in a year when the temperature drops rapidly. After a cold air, it is common that the daily average temperature drops by 8℃ and 10℃. Therefore, this season is the turning point of climate change in many parts of China.
