What are the characteristics of cold dew solar terms?

The temperature drops, there is less rain and dryness, and the morning dew is colder.

1, temperature drop

The arrival of cold dew solar terms will lead to a sudden drop in temperature, a cold air may lead to a drop in temperature, and an autumn rain may also lead to a drop in temperature. After the autumn rain, the temperature will basically drop by 8℃, 10℃.

2. Dry with little rain

It may not rain after the cold dew solar term. At this time, it is generally controlled by high pressure, resulting in a large temperature difference between day and night. The weather is very cold and the air is very dry at this time. So pay attention to autumn dryness. It is advisable to eat foods that clear away heat, promote fluid production and moisten dryness during this time.

3. Morning dew is cooler

In the morning of cold dew and solar terms, there will be dew on the leaves of some plants because the temperature in the morning is very low. Therefore, when you go out in the morning with cold dew and solar terms, you should pay attention to keeping warm, and reduce your clothes at noon to avoid catching a cold due to temperature difference.

Cold dew agricultural activities

After the cold dew, if there is strong cold air going south, the cold dew wind weather with low temperature and strong wind is easy to appear in the south. Cold dew wind is a chilling injury caused by the invasion of cold air in autumn, which reduces rice production. It is one of the main meteorological disasters in the growth period of late rice in southern China, which mostly occurs around the cold dew festival in the southern lunar calendar. Therefore, Guangdong, Guangxi and Fujian are called cold dew wind, and the Yangtze River basin is called autumn low temperature.

In the cold dew season, wheat should be sown in the north, not late, so as not to reduce production. South China should sow rape and plant broad beans in due course. There will be a disastrous weather in South China-Mianyu, which is characterized by high humidity, more clouds, less sunshine and more cloudy days. After that, the number of foggy days will increase obviously, which will directly affect the progress and quality of Sanqiu. Therefore, it is necessary to use the weather forecast to harvest and sow in sunny days.
