What is the annual cold dew? What season is the temperature over?

The cold dew we are talking about is not meteorological, but solar terms. Cold dew in this solar term, people will begin to feel the change of temperature. So what is the annual cold dew temperature? What season is after the cold dew? Let's analyze and discuss our old almanac with you!

What is the annual temperature of cold dew?

The regional difference of the average temperature distribution from June 5th to 10 in China is obvious. The average temperature in most parts of South China is above 22, and Hainan is even higher, above 25, and it has not yet come out of summer; Jianghuai and Jiangnan are generally between 15-20, and the southeast, North China and Huanghuai are between 8- 16. At this time, the average temperature in the northwest and parts of the north-central part of the northeast has reached below 8. The average temperature in some plateau areas of Qinghai Province is even lower than 0.

Although it is only a short 15 day from the cold dew to the first frost of the solar term, the temperature drops rapidly within one year. After cold air, the average daily temperature usually drops by 8 degrees, 10 degrees. Therefore, this season is the turning point of climate change in many parts of China.

After the cold dew, the cold air in the north has a certain influence, and most parts of the country are controlled by cold high pressure, and the rainy season is over. The weather is usually warm during the day and cool at night. The sky is clear and it is a scene of late autumn. In normal years, the 10 isotherm moves southward to the Qinling-Huaihe line, and generally falls below 0 to the north of the Great Wall.

What season is after the cold dew?

Cold dew is the solar term in autumn, after which it is the first frost, but the first frost is the last solar term in autumn, after which it enters winter. Cold dew means that the temperature is lower than that of the white dew, and the dew on the ground is colder and will soon condense into frost. White dew, cold dew and first frost all indicate the phenomenon of water vapor condensation, and cold dew is the transition from cold to cold.

Cold dew, cold dew, will freeze. When the cold dew is white dew, the weather turns cold and dew begins to appear. When there is cold dew, there will be more dew and the temperature will be lower. So some people say that cold is dew, white first and then cold, which means that the climate will gradually turn cold. Water vapor condenses into dew.
