Statistics of historical data show that the situation is different in different places and different years. Generally speaking, the average minimum temperature of severe cold solar terms in the north is lower than that of slight cold solar terms. The south is the opposite.

During the slight cold season, most parts of China have entered a severe cold period, with frozen soil and rivers frozen. In addition, the cold air in the north continues to go south and the weather is cold. People call it "counting nine cold days" Although it is not as cold in the south of our country as in the north, the temperature has dropped obviously. The coldest time in the south is slight cold, between rain and fright. It is dry and cold when it is a little cold, and it is wet and cold after the rain.

Characteristics of slight cold

When the sun meridian reaches 285 degrees, the slight cold solar term begins. Cold means cold, and slight cold means the degree of cold.

In the south of China, winter is very warm. The middle of winter is 1 month, with frost and snow attacking and often freezing. The lowest temperature is about-10℃. The lowest temperature in northern South China is rarely below MINUS 5℃, and the low temperature below 0℃ in southern South China is even rarer. The coldest area in the middle of winter in China is the northern part of Heilongjiang, and the lowest temperature can reach about MINUS 40℃. It's freezing, dripping into ice.

The low-altitude valley is the warmest place in the middle of winter in most parts of southern China. The average temperature in 65438+ 10 is around 12℃, and only a few teenagers may have a low temperature below 0℃. In addition, the inversion effect is very significant, so tropical fruits such as bananas and mangoes can grow well.

As the saying goes, "March 9th is cold". "Sanjiu" is mostly from 65438+1October 9 to 17, which is also within the slight cold solar terms. But this is just a general rule. In a few years, a bad cold may be colder than a mild one.

Citrus "was born in the south" generally requires a minimum temperature of not less than minus 5℃ and an annual temperature higher than 15℃, which can be met in most parts of South China and almost all subtropical plants. Only in this way, the unique climatic conditions should be a very important factor.

Slight cold has "third class"

The ancients used phenological representations of flowers, birds, grasses and insects to annotate each solar term, and each climate had a response, that is, the most representative phenology was extracted as the phenological response of this climate. Then the climate of each climate is integrated to form 72 climates with 24 solar terms.

Among the 24 solar terms, only the white dew and slight cold are completely recognized by birds. The ancients thought that "birds are not on fire", and birds have unparalleled talent in sensing the flow of yin and yang.

The story of Han Xiao described by the ancients is: waiting for Yanbei Township, waiting for magpies to build nests, waiting for pheasants to build nests. Wild geese move northward, magpies build nests, and pheasants sing.

Yanbei Township (Xiang). The meaning of hometown and guide. When the sun goes down, the geese will avoid the heat and return. Today, they will fly to the north of the country, and they will all return to the beginning of spring, so the birds will be angry first.

Magpies began to build nests. Magpie, the door of the magpie's nest is too old. From the solstice in beginning of winter to Tianyuan, and then to the solar term in the next year, magpies can nest and know what to do.

It's only a matter of time. Pheasant, a civilized bird, is also a sunny bird; "Pheasant" means singing. The pheasant will sing because of Yang's growth near April 9th.

Slight cold solar terms knowledge 3 little common sense about slight cold solar terms

Slight cold tonic is based on people's diet.

Speaking of tonic, there has been a saying since ancient times that "three nine make up one winter, and there will be no disease in the coming year". After eating in spring, summer and autumn, the yin, yang, qi and blood of zang-fu organs will decrease to some extent. Reasonable tonic can not only replenish qi, blood and body fluid in time to resist the cold, but also make young people suffer from less diseases in the future and achieve the goal of getting twice the result with half the effort. Tonifying in winter, combining food tonic with medicine tonic, and warming tonic is appropriate.

Sun Simiao, a famous doctor in the Tang Dynasty, pointed out: "The foundation of peace of mind must be based on food ... those who don't know how to eat correctly are not enough to survive ... so food can dispel evil spirits and stabilize viscera." This shows the effect of diet on human body. Although the light snow solar term has been cold for several days, it is understandable that people make up for it, but it is essential to make up for it. We should understand the meaning of dietary taboos according to the principle of "different from person to person". The dietary instructions of the Yuan Dynasty emphasized: "Diet is for health, but I don't know whether the physical properties are suitable for each other. Even if they are mixed together, it will lead to internal discord and cause great disaster. " Therefore, young people should not be hurt by the "five flavors" when taking supplements, but should selectively take supplements according to their own situation.

Fat, sweet and delicious, eating too much will hurt your health.

Carbohydrate mainly comes from cereals, so young people should ensure adequate appetite, pay attention to the proportion of coarse grains in flour and rice and take in appropriate amount of fat, which are all considerations when choosing medicinal diet for tonic. But young people have the characteristics of young people. People often eat greasy and spicy products and attract uninvited guests-"acne", which brings endless troubles to young people.

Warming is the best way to keep warm.

From the point of view of diet health, we should pay special attention to eating more warm food in our daily diet to supplement our health and prevent the invasion of cold climate. Commonly used tonics include Ginseng, Astragalus, Colla Corii Asini, Cordyceps sinensis, Polygonum Multiflori Radix, Lycium barbarum and Angelica sinensis. Dietary supplement should choose mutton, dog meat, pork, chicken, duck, eel, turtle, Spanish mackerel, sea shrimp and other foods such as walnut kernel, jujube, longan, sesame, yam, lotus seed, lily, chestnut, etc. All the above foods have the effects of nourishing spleen and stomach, warming kidney and strengthening yang, strengthening spleen and resolving phlegm, relieving cough and tonifying lung. Of course, people who are too hot, too solid and easy to get angry should pay attention to slow tonic and eat less.

During the winter solstice, the ground gets the least solar heat, but some heat in the deep soil can still be emitted upwards, so it is not the coldest time all year round. In the slight cold, the heat in the deep soil is lost to the lowest point. Although the days are a little longer and the sun's light and heat are slightly increased, it is actually the most difficult time to make a living, so it becomes the coldest season all year round.

China's traditional culture emphasizes "extremes meet" and thinks that the "day" of alternating cold and summer is to recover quickly after a cold. If you caught a bad cold before the slight cold, you can't just feel "recovered" after the coldest. Therefore, it is in line with the thinking habit of China people to put the severe cold behind them and let them return to beginning of spring quickly after the severe cold.
