Is the big cold necessarily colder than the small cold?

The Great Cold is the last of the 24 solar terms. Fighting fingers ugly; The ecliptic longitude of the sun reaches 300°; It is held on January 20-21 of the Gregorian calendar every year. Dahan, like Xiaohan, is also a solar term that indicates the degree of coldness of the weather, and Dahan means that the weather is cold to the extreme.

According to China's long-term meteorological records, there is no small cold in the northern region; But for most of the south, the coldest is during the Great Cold Solar Term. As soon as the cold passes, a new cycle begins, which is the so-called winter.

As the saying goes: "Flowers and trees are in season, and birds are singing to report the agricultural time". Flowers, trees, birds, beasts and birds all move according to the seasons, so their regular actions are regarded as an important symbol to distinguish the seasonal solar terms.

In ancient China, the Great Cold was divided into three phases: "one is chicken milk; Second, the migratory birds are severely ill; Three waits for Mizusawa to have a strong belly. "That is, when it comes to the big cold solar term, you can hatch chicks.

However, eagle falcons and other signs of birds are in a state of extremely strong predation ability, hovering in the air everywhere in search of food to replenish the body's energy.

During the last five days of the year, the ice freezes until it is the strongest and thickest, and children can skate on the river to their heart's content (the average daily temperature can only be carried out when the average daily temperature is below -5 for many consecutive days, which is usually seen in areas north of the Yellow River). In addition, the flower trade wind weather that appeared in the Great Cold is "one is Ruixiang, the second is orchid, and the third is alum (born in the Jiangnan area)". It can also be used as an important symbol to judge the great cold.

According to the customs of the Great Cold in our country, especially in the countryside, every time the Great Cold Festival, people begin to be busy removing the old and clothing the new, pickling New Year's dishes, and preparing New Year's goods.

During the period from the Great Cold to the beginning of spring, there are many important folk customs and festivals. Such as the tail tooth festival, the festival stove and Chinese New Year's Eve, etc., sometimes even the largest festival in our country, the Spring Festival, is also in this solar term. The Great Cold Solar Term is filled with an atmosphere of joy and joy, and it is a cheerful and relaxing solar term.

The tail tooth originates from the custom of worshipping the land to make "teeth". The so-called second day of February is the first tooth, and in the future, every second and sixteenth day of the first month will do "teeth", and it will be the tail tooth on the sixteenth day of the twelfth month of the lunar calendar. The tail tooth has the same spring cake (called run cake in the south) to eat on the second day of February, and on this day the buyers and sellers have to set up a banquet, and the white chicken is an indispensable dish on the banquet.

It is said that whoever the head of the chicken faces indicates who the boss will fire next year. Therefore, some bosses now generally face the head of the chicken towards themselves, so that employees can enjoy the food with peace of mind and have a peaceful year when they return home.

Hello dear. No. From the perspective of spatial distribution, in most areas north of the Yellow River, the average minimum temperature during the "Great Cold" solar term is lower than that of the Xiaohan solar term. In the area between the Yangtze River and the Yellow River, the "big cold" and "small cold" are as cold as ever; In the area south of the Yangtze River, the "Xiaohan" solar term is colder than the "Dahan" solar term.

However, this is based on the average situation, and in a specific year, whether the "big cold" or the "small cold" is affected by many factors, such as the weather circulation situation of the year, etc., it is necessary to analyze it according to the actual situation.

Compared with the big cold, the small cold is colder, because during the small cold season, the precipitation and sunshine are strong**, the temperature continues to drop, and the wind blows more fiercely.

I think Dahan will be colder, because from the name it looks like Dahan, it will be colder than Xiaohan, so the temperature will definitely be lower than Xiaohan.

The weather in the big cold is colder, the temperature is lower, you must pay attention to keep warm, and most of the cold is in the third and ninth days.

It will be colder during the small cold period; According to meteorological data, Xiaohan is the coldest time of the year.

It's colder during the light cold period.

In northern China, there is a saying that "a small cold is better than a big cold, and it is not uncommon to see it", which means that the small cold solar term is colder than the big cold solar term, which is not unusual.

Xiaohan is generally in the period from "29" to "39", Xiaohan is the coldest time of the year in northern China, and the temperature rises slightly after the big cold. The coldest in southern China is in the 49th day, 49 is colder than 39, and the big cold in the southern region is colder than the small cold in the 49th hour.

Xiaohan and Dahan both belong to the winter solar terms, of which Xiaohan is the 5th solar term in winter, and Dahan is the 6th solar term in winter, Xiaohan and Dahan are both solar terms that indicate the change of cold and warm weather, and the characteristics of Xiaohan solar terms are cold, but they are not cold to the extreme, so there may be colder times later.

The phenological phenomenon of the Xiaohan solar term.

In ancient China, "Xiaohan" was divided into three phases: "one is the first to wait for the wild goose to go to Beixiang, the second is for the magpie to start the nest, and the third is for the pheasant to start the robin." The ancients believed that the geese in the migratory birds migrated along with the yin and the lack of yang, and the yang energy had moved at this time, so the geese began to migrate northward.

At this time, magpies can be seen everywhere in the north, and they feel the yang energy and begin to build nests; The "robin" of "pheasant" means to chirp, and the pheasant will feel the growth of yang energy and chirp when it is close to forty-nine.
