What is the meaning of "Cold Dew"?
Cold Dew: The temperature is lower, and the air has already formed dew, gradually showing a sense of cold.The Cold Dew solar term starts at the end of October and ends in late October. The sun's direct point continues to move southward in the southern hemisphere, and the angle of sunlight in the northern hemisphere begins to tilt significantly. The amount of solar heat received by the ground is significantly reduced compared to summer, and the influence of cold air sometimes extends to South China.
In the Guangdong area, there is a folk proverb: "After three days of Cold Dew, one needs to look for a bridge when crossing water," which means that the weather has turned cooler and one can no longer walk barefoot across rivers or into fields as before. It can be seen that during the Cold Dew period, people can clearly feel the change of seasons. More regions and more people begin to use the word "cold" to express their feelings about the weather.
Is "Cold Dew" a symbol of the weather starting to get colder?
The "Cold Dew" solar term is a symbol of the weather turning cooler, marking the transition from cool to cold weather. The dewdrops shine with cold light, as the folk saying goes, "Cold Dew, Cold Dew, everywhere is cold dew."A rapid drop in temperature is a characteristic of the Cold Dew solar term. After a strong cold front brings autumn winds and rains, it is common for temperatures to drop by 8°C or 10°C. However, the duration of such weather is usually short (except in the western regions), and under the control of a cold high-pressure system, it is warm during the day but cool at night, often with clear and fresh autumn weather.
In October, the regional differences in China's average temperature are obvious. In South China, the average temperature in most areas is above 22°C, with Hainan even higher than 25°C, and it has not yet left summer. In the Jianghuai and Jiangnan areas, the average temperature ranges between 15°C and 20°C. In the southern part of Northeast China, North China, and the Yellow River basin, it ranges between 8°C and 16°C. Meanwhile, some parts of the northwest and the central and northern parts of Northeast China have average temperatures below 8°C. In some plateau areas of Qinghai Province, the average temperature even drops below 0°C.
