, cold dew is the 17th solar term and belongs to the solar term in autumn. The climate in autumn is dry and getting colder and colder. What are the characteristics of cold dew solar term? When is the cold dew solar term? Next, let's follow the old yellow calendar of this issue and have a look!
Q: when is the 2019 cold dew solar term? A: the 2019 cold dew solar term is on Tuesday, October 8, the tenth day of the ninth lunar month. What are the characteristics of theand
cold dew solar terms? 1. The temperature drops faster and drier, and the temperature drops faster is a characteristic 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 ℃. However, most of the stormy weather does not last long (except in West China). Under the control of cold and high pressure, it is warm in the day and cool at night. During the day, it is often clear and crisp in autumn. The weather has also become drier. It is understood that cold dew is a festival in late autumn. The word "cold" first appeared in the 24 solar terms. At this time, the wild geese fly south and the chrysanthemums turn yellow. Compared with the "White Dew" a month ago, the temperature is lower, there is more dew and a chill.
2. Cold air frequently goes south. It is known from climatology that after the cold dew, the cold air in the North has a certain force. Most parts of China are under the control of cold 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. After entering the "cold dew", the invasion frequency and intensity of the cold air in the north will increase. A major feature of the "cold dew" solar term is that the temperature drops rapidly. After the autumn wind and rain brought by a strong cold air, it is common for the temperature to drop by 8 ℃ to 10 ℃.
3. There are great differences in the distribution of average temperature. In October, there are obvious regional differences in the distribution of average temperature in China. In South China, the average temperature is above 22 ℃ in most areas, higher in Hainan, above 25 ℃, and has not gone out of summer; Jianghuai and Jiangnan are generally between 15 ℃ - 20 ℃, and the south of Northeast China, North China and Huanghuai are between 8 ℃ and 16 ℃. At this time, the average temperature in some parts of Northwest China and the middle and north of Northeast China has reached below 8 ℃. The average temperature in some plateau areas of Qinghai Province is even below 0 ℃.
4. The weather and precipitation are scarce and thunderstorms almost disappear. October 8 is the "cold dew" in the 24 solar terms, which means the turning point from cool to cold in the year. With the arrival of cold dew, most parts of China will turn cool. The northeast and northwest regions have entered or are about to enter winter, with less rain. 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. Thunderstorms have disappeared in most parts of China's mainland, and thunder can be heard only in some areas of Yunnan, Sichuan and Guizhou. The precipitation in October in North China is generally only half or less of that in September, while that in Northwest China is only a few millimeters to more than 20 millimeters. Drought and little rain often bring difficulties to timely sowing of winter wheat, which has become one of the main limiting factors for high yield of dryland wheat.https://www.dailyq-a.com/Culture/28677.html
