Cold dew solar term characteristic map

The sudden drop in temperature is a feature of the cold dew solar terms. It is common for the temperature to drop by 8℃ and 10℃ after the autumn rain brought by a strong cold air. However, most stormy weather does not last long (except in western China). Under the control of cold and high pressure, the days are warm and the nights are cool. In autumn, the weather is often crisp and dry.

2. Cold air frequently goes south.

According to climatology, 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. The weather is usually warm during the day and cool at night, with clear skies in Wan Li and a scene of late autumn. In normal years, at this time, the isotherm of 10℃ has moved southward to the Qinling Mountains and Huaihe River, and generally falls below 0℃ to the north of the Great Wall. The first frost can be seen in most years in Beijing, the capital.

3. The weather and precipitation are scarce, and thunderstorms almost disappear.

65438+10.8 is the "cold dew" in the 24 solar terms, which means the turning point from cold to cold in a year. With the arrival of cold dew, most parts of China will turn cold, and the northeast and northwest regions have entered or will soon enter winter, with less rain. ?

The custom of cold dew solar terms

Gordon 1

Because the Double Ninth Festival is around the cold dew solar terms, the climate with pleasant cold dew solar terms is very suitable for mountaineering, so the custom of climbing slowly on the Double Ninth Festival has become the custom of cold dew solar terms. Climbing means "step by step" and "long life".

2. Look at the red leaves

In the cold dew season, the autumn wind is rustling, and the red leaves on the mountain are as beautiful as Xiajin and picturesque. Walking on the winding path and looking at the hillside, you will see clusters of red leaves.

3. Fishing in autumn

Because of the cold dew season, the temperature drops rapidly, the sunlight in the deep water can't penetrate, and the fish swim to the shallow water with higher water temperature, so it is called "autumn fishing".
