Introduction: The solar terms are one of our country’s traditional cultures since ancient times, and different solar terms represent different meanings. So which season is Cold Dew? Analysis of the weather characteristics of the Cold Dew solar term! Mr. Shui Mo has carefully compiled detailed information about the eighth month of the lunar calendar in 2018. If you want to know the auspicious and inauspicious days in the eighth month of the lunar calendar, please go to Mr. Shui Mo.Which season is Cold Dew?Cold Dew is the seventeenth solar term in the twenty-four solar terms of the lunar calendar and the fifth solar term of autumn, marking the official start of the autumn season; it falls between October 7th and 9th of the Gregorian calendar every year. When the sun reaches 195° ecliptic longitude. "Collected Explanations of the 72 Seasonal Changes" says: "In the ninth month, the dew is cold and is about to condense." Cold Dew means that the temperature is lower than that during White Dew, the dew on the ground is colder, and is about to condense into frost. During the Cold Dew season, the Nanling Mountains and vast areas to the north have entered autumn, the northeast has entered late autumn, and the northwest has entered or is about to enter winter.Analysis of weather characteristics during the Cold Dew solar term!The temperature drops quickly during Cold Dew, and the weather becomes drier <br /> A characteristic of the Cold Dew solar term is that the temperature drops quickly. After a strong cold front brings autumn winds and rains, it is not uncommon for the temperature to drop by about eight or ten degrees. However, windy and rainy weather usually does not last long (except in western China). Under the control of cold high pressure, it is warm during the day and cool at night, and the daytime is often clear and cool.The weather also becomes drier during the Cold Dew season. It is understood that Cold Dew is a festival in late autumn, and the word "cold" appears first among the 24 solar terms. At this time, wild geese fly south and chrysanthemums turn yellow. Compared with the White Dew season a month ago, the temperature is lower, there is more dew, and it is chilly. The average temperature distribution of Cold Dew varies greatly <br /> Cold Dew falls in October of the Gregorian calendar, and the average temperature distribution in China varies significantly across regions. In South China, the average temperature in most areas is above 22℃, and even higher in Hainan, above 25℃. Summer has not yet arrived. The temperatures in Jianghuai and Jiangnan areas are generally between 15℃ and 20℃, while the temperatures in southern Northeast China, North China, and Huanghuai are between 8℃ and 16℃. At this time, the average temperature in some areas of Northwest China and central and northern Northeast China has dropped below 8℃. The average temperature in some plateau areas of Qinghai Province is even below 0℃. Cold air frequently moves southwards during the Cold Dew period. <br /> From a climatological point of view, after the Cold Dew period, the cold air in the north has gained some strength, and most areas of China are under the control of cold high pressure, and the rainy season ends. The weather is often warm during the day and cool at night, with clear skies, a scene reminiscent of late autumn. In normal years, the 10℃ isotherm has moved south to the Qinling Mountains and the Huaihe River, while the temperature north of the Great Wall generally drops below 0℃. In most years, the first frost can be seen in the capital Beijing at this time. After entering the Cold Dew season, the frequency and intensity of cold air invasions from the north will increase. A rapid drop in temperature is a major feature of the Cold Dew season. After an autumn wind and rain brought by a strong cold air, it is common for the temperature to drop by 8℃ to 10℃. Cold Dew has little precipitation and thunderstorms almost disappear <br /> The arrival of Cold Dew marks the transition from cool to cold in the year. During the Cold Dew season, most parts of my country will become cooler. The Northeast and Northwest regions have entered or are about to enter winter, and the rain will gradually decrease. Except for the Qinghai-Tibet Plateau where snow falls all year round, snow has generally already started to fall in Northeast China and northern Xinjiang. During the Cold Dew season, thunderstorms have disappeared in most parts of mainland my country, and thunder can only be heard in parts of Yunnan, Sichuan and Guizhou. The precipitation in North China in October is generally only half of that in September or less, while in Northwest China it is only a few millimeters to more than 20 millimeters. Drought and low rainfall often make it difficult to sow winter wheat in time, becoming one of the main limiting factors for achieving high yields of dryland wheat. |
