When was the Great Cold in 2022? How many minutes and seconds?

The solar term of the severe cold in 2022 is 65438+10: 38: 56 on the Gregorian calendar in 202210/8, on the Thursday of the lunar calendar 12 18.

The Great Cold is the last of the 24 solar terms, and it is called "Great Cold" every year when the sun reaches 300 degrees on June 20-2 1 day of the Gregorian calendar. There is a folk saying that "a slight cold is the most important thing, and it is cold without wind." Great cold refers to extremely cold weather. Although the solar term from winter solstice is the lowest in the northern hemisphere, it is also the coldest time of the year. After beginning of winter, the slight cold and the great cold reached the sun, especially the great cold, which was particularly cold. This is because after the winter solstice, the direct point of sunlight will gradually move northward, but in the following time, the direct point of sunlight will always be in the southern hemisphere, and the heat in the northern hemisphere will always be lost, and the heat absorbed during the day is still less than the heat released at night. Therefore, after the winter solstice, the temperature in the northern hemisphere will continue to decrease, and the temperature will be the lowest during the great cold solar term, so the great cold is the coldest solar term in a year.

The meaning of severe cold solar terms

Great cold means extreme cold, and great cold means very cold weather.

Initially, during the winter solstice in the northern hemisphere of China, the sun directly shines on the Tropic of Capricorn. The shortest day and the longest night. The ground receives the least light and heat, and the weather should be the coldest. However, the actual cooling is during the solar terms of slight cold and severe cold from winter to the future, which is the so-called "March 9 cold weather". This is because during the Great Cold Festival, although the daytime is slightly longer than the winter solstice, the daytime is still shorter and the night is longer. The heat radiated from the sun to the ground is less than that radiated from the ground to the air, so the temperature keeps dropping. In addition, cold waves from the polar regions, Siberia and the Mongolian Plateau frequently go south, constantly invading vast areas of China and promoting the emergence of the lowest temperature throughout the year.

Seasonal characteristics of severe cold

During the severe cold solar term, the atmospheric circulation is relatively stable, and the adjustment period of circulation is about 20 days. When this circulation is adjusted, there will often be a wide range of rain and snow weather and strong winds to cool down. When the west of 80 degrees east longitude is a long wave ridge and East Asia is a coastal trough, under the influence of northwest wind flow control and constantly supplemented cold air, China will have a sustained low temperature.

Like slight cold, great cold is also a solar term indicating the degree of cold weather. Modern meteorological observation records show that in some areas of China, severe cold is not as good as slight cold, but in some years and a few coastal areas, the annual minimum temperature will still appear in the severe cold solar terms. Therefore, it is necessary to continue to do a good job in the cold protection of crops, especially to protect livestock from wintering.

In the severe cold season, the average temperature in most parts of southern China is 6℃ to 8℃, which is nearly 65438 0℃ higher than slight cold. The proverb "slight cold and cold, cold into a ball" shows that the great cold solar terms are also the cold period of the year.

Health care skills of bad cold

Bushen qi

Winter is the best season for tonic, and according to the theory of Huangdi Neijing, winter is also the best season for tonifying kidney. The four seasons in Huangdi Neijing correspond to different organs, and winter corresponds to kidney. Of course, this kidney is not only a solid organ of western medicine, but also a concept of Chinese medicine, including reproductive organs and urinary system. A person's kidney is full of qi and blood, and it is prone to many diseases. Therefore, it is particularly necessary to tonify the kidney in winter.

It is recommended to go outdoors to bask in the sun every day.

In winter, the sunshine is mild and the ultraviolet rays are weak, which does little harm to people's skin. So I suggest going to the sun every day. Sunbathing children can help them absorb calcium and help them grow taller. Sunbathing for adults is good for their health.
