The time of the Great Cold solar term in 2022
Great Cold, the last solar term in the twenty-four solar terms, from January 20 to 22 every year, when the sun is at 300° ecliptic longitude The big cold solar term means the end of the four seasons and the beginning of the new year.After the great cold, it is the beginning of spring, which will usher in the cycle of solar terms in the new year.So the big cold solar term in 2022 is at 10:30 on January 20, 2022 in the Gregorian calendar, which is December 18, the year of Xin Chou in the lunar calendar.During the Great Cold Season, the cold waves travel south frequently, which is the coldest period of the year in most parts of China.Like the Minor Cold, the Great Cold is also a solar term that characterizes the degree of cold weather.
Climatic characteristics of the Great Cold solar term in 2022
At this time of the Great Cold, cold waves are frequent to the south, and it is the coldest period of the year in some parts of China.The wind is strong, the temperature is low, and the snow does not melt on the ground , showing a frosty scene of ice and snow and freezing cold.At this time, the cold wave is frequent southward, which is the cold period of the year in most parts of our country.The wind is strong, the temperature is low, and the snow does not melt on the ground.After the big cold, like the small cold, the big cold is also a solar term that indicates the degree of cold weather.Although modern meteorological observation records show that in some areas of China, the big cold is not as good as the small cold, but in some years and a few places along the coast, the lowest temperature throughout the year will still appear in the big cold solar term.During the big cold season, the average temperature in most parts of southern China is mostly 6°C to 8°C, nearly 1°C higher than the minor cold.The proverb "Small cold and big cold, cold into a ball" indicates that the Great Cold solar term is also a cold period of the year.
Minor cold and major cold are the least rainy periods of the year.With the perennial cold and solar terms, the rainfall in most parts of southern China has only increased slightly compared with the previous period, 5 to 10 mm in most parts of southern China, and only 1 to 5 mm in the northwest plateau and mountains.South China is dry in winter, and the water consumption during winter crops is relatively small, and the contradiction between water supply and demand in farmland is generally not prominent.But "don’t blame the weather for the bitter cold, rain and snow, the snow will be left to next year’s wheat".In the case of sparse rain and snow, according to different farming habits and conditions in different regions, timely watering is undoubtedly beneficial to the growth of wheat crops.
The phenological characteristics of the Great Cold solar term in 2022
Like other solar terms, the ancients also found out the typical characteristics of animal responses and natural changes during the Great Cold Season, that is, the "Three Weathers of Great Cold"."Book of Yi Zhou Shi Xun" said:"On the day of the great cold, the chicken begins to milk.For another five days, the bird of prey suffers severe illness.For another five days, the belly becomes firm." The chickens start laying eggs and the chicks can be hatched; in another 5 days, the falcons will circle and prey more violently; in another 5 days, a hard layer of ice will form in the middle of the river pond.If the "Three Hours of Great Cold" summarized by the ancients based on these phenomena and characteristics is abnormal, it will be regarded as a bad omen.
