Q: what month and day will the frost fall in 2020? A: the frost fall in 2020 is the time of the Gregorian calendar: October 23, 2020. Lunar date: the seventh day of September (small).and
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 ofand
, 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.and
Su Shi, a great literary scholar in the Northern Song Dynasty, wrote a poem: "a thousand trees make a yellow, and only Hibiscus is fragrant alone." the climate in Sichuan Basin is mild. During frost, the fields are green, orange, yellow and orange green, autumn chrysanthemums are in full bloom, and hibiscus trees are in full bloom, making the rich "Tianfu" more gorgeous.

frost, which is the last solar term in autumn and the solar term for the transition from autumn to winter. This solar term is called frost fall, but frost does not fall from the sky, but condenses when it meets things. 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.

The old man in Quanzhou said that eating persimmons by frost is: eating Ding persimmons by frost will not have a runny nose. In some places, the explanation for this custom is: eat pancakes on the day of frost, otherwise your lips will crack all winter. At this time, people living in rural areas will climb tall persimmon trees and pick some bright and sweet persimmons to eat.and
frost fall, as the transitional solar term between autumn and winter, it is particularly important to take necessary dietary supplements at this time. In tonic, we should focus on "moistening dryness, consolidating exterior and Supplementing Qi". For example, royal jelly is more suitable for the frail elderly. Take it once in the morning and once in the evening, which is good for promoting sleep and defecation; If it is a woman over 40 years old, eating a little properly can also make the skin smooth, but it is not suitable for children. For example, American ginseng can nourish yin and generate saliva. For tumor patients, postoperative patients and patients with low leukocyte, American ginseng can help enhance the body's immunity. Other chronic diseases such as diabetes can also be eaten with American ginseng. For example, Korean ginseng is relatively warm and suitable for people with cold hands and feet, fear of cold and white face, but it is not suitable for people with phlegm, red face, impatience, thirst, bitter mouth and dry stool.
