climatic characteristics of cold dew 1. The weather becomes cold. The cold dew solar term begins at the end of early October. At this time, the direct point of the sun will continue to move southward in the southern hemisphere. The angle of sunlight in the northern hemisphere obviously begins to tilt and move. The solar heat that the ground can receive is significantly less than that in summer. At this time, the influence range caused by the cold air can also be extended to South China and will not end until late October. "When the cold dew passes through three dynasties, look for a bridge when crossing the water", which is a proverb circulating in Guangdong. It means that once the cold dew arrives, the temperature becomes lower. It will be very cold if you cross the river or go to the field barefoot as before. During the cold dew period, due to the obvious climate change, people use the word "cold" to express their obvious changes in the season.

2. The temperature drops rapidly. The sudden drop of temperature is also one of the characteristics of cold dew solar terms. After a strong cold air brings autumn wind and rain, the temperature drops between 8 ℃ and 10 ℃, with a large range. However, with the exception of West China, most of these rainy days do not last long, and are controlled by cold and high pressure. They are warm in the day and cool at night. They feel more crisp in autumn during the day.

3. The average temperature distribution varies greatly. In October, there are obvious regional differences in the distribution of average temperature in China. In South China, the average temperature in most areas is above 22 ℃, and it is still some time before leaving in summer. The temperature in Jiangnan is generally between 15 ℃ and 20 ℃, and that in the south of Northeast China and North China is 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 is even below 0 ℃.
