What is the temperature of the cold dew?

After the cold dew, it belongs to the late autumn period, some areas in the north have gradually transitioned to winter, and most areas in the south belong to the late autumn, but there will be obvious cooling in the whole country.

In the cold dew season, dew increases and the temperature decreases. At this time, frost will appear in some parts of China. In the north, it is already a scene of late autumn, with white clouds and red leaves and occasional early frost. In the south, autumn is getting stronger and cicadas are dying. At this time, the temperature in most parts of South China continues to drop, and the average daily temperature in South China is less than 20℃. Even in the areas along the Yangtze River, it is difficult for the temperature to rise above 30℃, and the minimum temperature may drop below 10℃. Except for a few valley lowlands, the average climate temperature in the northwest plateau is generally lower than 10℃, which belongs to winter according to the standard of climate division of four seasons. What is the difference between cold dew and white dew?

The white dew is the third solar term in autumn, and the cold dew is the fifth solar term in autumn. One belongs to early autumn and the other belongs to late autumn. Although there is dew condensation, the difference is quite big.

Millennium solar terms:

Millennium, the fifteenth of the twenty-four solar terms, the third solar term in autumn, the end of the lunar calendar and the beginning of the unitary month. Fighting fingers; The sun reaches longitude 165 degrees; Gregorian calendar September 7-9.

The ancients used four seasons with five elements, autumn was gold, gold and white, and white was used to describe autumn dew, hence the name Bailu. During the white dew, the summer monsoon is gradually replaced by the winter monsoon, and the cold air changes from defense to attack. In addition, when the direct point of the sun moves south, the sunshine time in the northern hemisphere becomes shorter, the light intensity weakens, and the ground radiation dissipates heat quickly, so the cooling speed gradually accelerates. The Millennium basically ended the sultry summer, and the weather gradually turned cold, and the cold gave birth to dew condensation.

Cold dew solar terms:

Cold dew, the seventeenth solar term in the twenty-four solar terms, the fifth solar term in autumn and the beginning of the dry calendar. Finger e; Does the sun reach longitude 195? ; It will be celebrated on Gregorian calendar1October 7 -9 10.

"Twenty-four solar terms" said: September solar terms, cold dew, will condense. At this time, the temperature is lower than the white dew, with more dew and cold weather, hence the name cold dew. After the cold dew, the cold air in the north has a certain influence, and most parts of China are controlled by cold high pressure, and the rainy season is over. From the climate characteristics, in the cold dew season, the autumn in the south is getting stronger, cool and cool, with little rain and dryness; The vast areas in the north have entered or will enter winter from late autumn.
