One of the 24 solar terms of the first frost, the weather is getting colder and frosty. The first frost time is Gregorian calendar1October 23-24 10, and when the sun reaches 2 10 degrees of the longitude of the Yellow River, it is the first frost in the 24 solar terms. At this time, the ground heat dissipation in autumn is very large, and the temperature suddenly drops below 0 degrees. Water vapor in the air directly condenses on the ground or plants to form fine ice needles, and some become hexagonal frost flowers, which are white and loose in structure.

In ancient times, the first frost was divided into three stages: first, the jackal sacrificed animals; Second, the vegetation is yellow; Three stings are salty.

Jackals are sacrificial animals. The word "jackals are sacrificial animals" first appeared in Yizhoushu: "On the day of the first frost, jackals are sacrificial animals". He also said, "It is not good for jackals not to sacrifice animals." It means that in this solar term, the jackal began to catch prey, sacrificed the beast with the first thing he caught, and returned the book to heaven with the beast, which paved the way for offering autumn gold. Like the harvest of the new valley on the earth, it is used to worship the sky to show the return and pray for good weather in the coming year. It is the meaning of animals and the foundation of human beings.

Second, the vegetation will turn yellow. Paraquat is exhausted in autumn, and butterflies fly in first frost. In autumn, the west wind is rolling, knocking down leaves and blowing drafts. The gradually cooling climate has destroyed all the vitality of nature again and again. Green decreases, red disappears, and geese disappear. And people's emotions have also entered a deep trough. Don't hate to stay sad, wind and rain are bitter in late autumn, touching people's hearts.

Three stings are salty. The stinging insects are motionless in the cave and hang their heads into hibernation. Nature at this time is a silent beauty. After a vigorous spring, a lively summer, a festive autumn and the cycle of life, it entered a dormant state. There are no traces of bees and butterflies, and the stinging insects are silent, all preparing for the long winter. It is a gesture of practice, looking forward to the new students in the coming year.

The first folk activity in first frost:

In some parts of our country, people eat red persimmons in the first frost season.

In Shandong Province, there is an agricultural proverb, "Summer sorghum, Bailu Valley, first frost pulls radish", so first frost, Shandong people, like to eat radish.

Climatic characteristics of the first frost;

The solar term of the first frost means that the weather is getting colder and first frost begins. To the south of latitude, the average temperature is around 16℃, and there are three solar terms before the first frost day. In the southern valley of South China, frost can only be seen in the dead of winter. Of course, even at the same latitude, the temperature and humidity of the air close to the stratum are different due to the difference of altitude and topography, and the first frost period and frost day are also different. In the first frost season, the cool autumn wind blew to Guangzhou, the flower city. The average temperature in northeast China, eastern Inner Mongolia and most parts of northwest China has been below 0℃.

Because there is frost when it is frozen (sometimes no frost is called black frost), autumn frost and spring frost are collectively called frost. Frost refers to the phenomenon of crop freezing injury caused by the sudden drop of temperature, and its harmful temperature varies with crops, varieties and growth periods. To form frost, the temperature of the ground or ground objects must drop below 0℃, and the water vapor content in the air on the ground should reach a certain level. Therefore, there may not be frost in first frost, and there may not be frost in first frost. However, due to the low temperature during frost, if the temperature continues to drop, it will easily lead to frost.

As far as the annual frost days are concerned, there are frost and snow in some parts of the Qinghai-Tibet Plateau even in summer, and the annual frost days are over 200, which is the place with the largest number of frost days in China.

The annual frost days in eastern Tibet, southern Qinghai, Qilian Mountains, western Sichuan Plateau, northwestern Yunnan, Tianshan Mountains, Altai Mountains, western mountainous areas of northern Xinjiang, northeast China and eastern Inner Mongolia all exceed 100 days, and the vast areas south of Huaihe River, Hanshui River and east of Dongpo of Qinghai-Tibet Plateau are all below 50 days, with only the annual frost days in the south of 25 north latitude, Sichuan Basin, south of Fuzhou and coastal areas of Guangdong and Guangxi being/kl.
