What is the solar term with the biggest temperature difference between day and night?

The solar term with the biggest temperature difference between day and night is the white dew.

"The Millennium is divided into autumn nights, and it is cool all night." September 7th is the "white dew" in the twenty-four solar terms of the lunar calendar, and it is the solar term with the largest temperature difference between day and night in a year. Experts suggest that in this festival, the public should always pay attention to the temperature changes, moderately increase or decrease clothing, and prevent colds.

After entering the Millennium solar terms, the warm air gradually retreated and the cold air began to attack. The Central Meteorological Observatory predicts that there will be no large-scale high-temperature weather in China in early September, and the temperature is more suitable, but the cold air force is increasing, so attention should be paid to prevention.

Meteorologists said that the Millennium is a typical autumn solar term, and the temperature difference between day and night is generally 10℃ to 15℃. The temperature drops rapidly, and autumn is getting stronger.

Millennium folk custom

1, clear dew

In China, there is a custom of "picking the dew" in the Millennium solar terms. In the Compendium of Materia Medica written by Li Shizhen in the Ming Dynasty, it said: "When the autumn dew is numerous, it is collected on a plate and fried like rice, which makes people not hungry for a long time." "The autumn dew on the head of a hundred herbs is collected when it is not embarrassing. The more sick you are, the thirst will be quenched, and people will be light and hungry. " The flower is exposed, which is a good color. Thus, dew-clearing has become the most special "ceremony" in the Millennium.

Yu Wang is the legendary water control hero Dayu, and the fishermen on Taihu Lake are called "water gods". Every year on the eighth day of the first month, Tomb-Sweeping Day, the seventh day of July and the Millennium, incense parties are held to commemorate Yu Wang. Among them, Tomb-Sweeping Day and Bailuyuan have the largest Spring and Autumn Festival, which lasted for one week.
