Introduction to frost term contains the meaning that the weather is getting colder and begins to frost. In the Sichuan basin with south latitude, the average temperature is mostly about 16 ℃, and there are three solar terms before the first frost date. In the valley area in the south of the basin, frost can only be seen in the middle of winter. Of course, even in places with the same latitude, due to different altitude and terrain, the temperature and humidity of the air near the stratum are different, and the initial frost period and frost days are different.

and

from a scientific point of view, the saying that "dew turns into frost" is inaccurate. The frozen dew formed by freezing dew drops is a small hard ice bead. Frost refers to the phenomenon of crop freezing damage caused by sharp temperature drop, and its damage temperature varies with crops, varieties and growth periods; To form frost, the temperature of the ground or ground object must be reduced below 0 ℃, and the moisture content in the air in the adjacent formation must reach a certain degree.

therefore, frost does not necessarily occur when frost occurs, and frost does not necessarily occur when frost occurs. However, because the temperature at the time of frost is relatively low, it is easy to cause frost if it continues to cool. After the frost of

, the basin began to collect and dig a large number of sweet potato. If the harvest and excavation is too early and the sweet potato has not been fully expanded, the yield will be affected; However, if the harvest and excavation is too late, it may suffer from early frost, and the sweet potato blocks are frozen and deteriorated, which is not resistant to storage. Therefore, it is very important to dig sweet potato in time.

frost, which is the last solar term in autumn and the solar term for the transition from autumn to winter.

When the temperature near the ground is lower than 0 ℃, the water vapor condenses into crystal frost flowers or ice needles.

,

, "frost" is a solar term that represents the change of temperature. It means that the weather turns cold, dew condenses into frost and begins to see frost. According to meteorological experts, "the beginning of frost" reflects the climatic characteristics of the Yellow River Basin. After the "frost" solar term, the influence of cold air southward will be more frequent, and the autumn will be thicker and thicker everywhere. The seasons of

,

and "frost fall" are also seasons. At this time, under the action of cold and warm air, it is easy to have atmospheric inversion, that is, the temperature of the upper atmosphere is higher than that of the lower atmosphere. Once the temperature inversion occurs, the pollutants in the near surface atmospheric environment will accumulate due to the lack of convection and diffusion, resulting in pollution, and a haze will come again.

,

and "frost beginning" reflect the climate characteristics of the Yellow River Basin. The first frost in autumn is called the first frost. The earlier the first frost, the greater the harm to crops. The first frost in China is gradually delayed from north to South and from high mountains to plains.

and

in addition to the areas with frost all year round, the earliest frost is in the north of Daxinganling, which is generally visible at the end of August; The first frost mostly occurs in September in most of Northeast China, Inner Mongolia and Northern Xinjiang; At the beginning of October, frost has appeared in Shenyang, Chengde, Yulin, Changdu Lhasa line; In early November, frost can be seen from Shandong Peninsula, Zhengzhou, Xi'an to Northwest Yunnan; Frost will not appear until early December in areas around 30 ° n in eastern China, Hanshui and 2 ° n in Yunnan Province; It was early January after the new year when the frost appeared in Xiamen, Guangzhou, Baise and Simao.

and

in the frost season, the cool autumn wind has blown to the flower city of Guangzhou. The average temperature in the north of Northeast China, the east of Inner Mongolia and most of the Northwest has been below 0 ℃, the soil is frozen, the winter crops stop growing and enter the overwintering period. Su Shi, a great literary scholar in the Northern Song Dynasty, wrote a poem: "thousands of trees sweep to make a yellow, only Hibiscus fragrance alone". The climate in the south is mild. During frost, the fields are green, orange, orange and green, autumn chrysanthemums are in full bloom, and hibiscus trees are in full bloom, which makes the land in the South more beautiful.
