is the cold dew solar term after the White Dew solar term, but many people are not very clear about the cold dew solar term, so what does 2020 cold dew mean? What is the approximate temperature of cold dew? Let's understand the solar term of cold dew with the old yellow calendar!
what does the 2020 cold dew mean: the temperature is lower than the White Dew. After the cold dew, the dew increases and the temperature is lower. At this time, there will be frost in some parts of China. It is late autumn in the north. There are white clouds and red leaves, and early frost occasionally. In the south, the autumn is getting thicker and the cicadas are silent and the lotus remains. Beijingers have more climbing customs. Jingshan Park, Badachu and Xiangshan are all good places for climbing. The double ninth Climbing Festival will attract many tourists. Dew is traditionally regarded as a sign of the cooling weather in China. The mid autumn White Dew solar term "dew condenses and turns white", and the autumn cold dew is "dew is cold and will condense into frost". Cold dew means that the temperature is lower than that of White Dew. The dew on the ground is colder and is about to condense into frost. In the cold dew season, Nanling and the vast areas to the north have entered autumn, and the northeast and northwest have entered or will enter winter.
what is the cold dew temperature? The rapid temperature drop is a feature of the cold dew solar term. After the autumn wind and rain brought by a strong cold air, it is common for the temperature to drop by 8 ℃ and 10 ℃. In October, the regional difference of average temperature distribution in China is obvious. Although the frost fall from the cold dew to the solar term behind it is only 15 days, it is a relatively rapid period of time in a year. It is common for the daily average temperature to drop by 8 ℃ and 10 ℃ after a cold air. Therefore, this season is a turning point of climate change in many parts of China. After the cold dew, the cold air in the North has a certain force. Most parts of China are under the control of cold and high pressure, and the rainy season ends. The weather is usually warm in the day and cool at night. The sky is clear for thousands of miles. It is a scene of late autumn. In normal years, the isotherm of 10 ℃ at this time has moved south to the Qinling Huaihe River line, and generally dropped below 0 ℃ to the north of the Great Wall. In most years of the capital Beijing, early frost can be seen at this time. In addition to the Qinghai Tibet Plateau, where snow flies all year round, snow has generally begun to fall in the northeast and Northern Xinjiang.https://www.dailyq-a.com/Culture/30275.html
