What are the phenological characteristics of the Great Cold?

The severe cold solar term is the last solar term from the winter solstice and the end of the twenty-four solar terms. So what does it mean to wait for three days? What are the phenological characteristics of the Great Cold? Let's take a look at Bian Xiao.

What do you mean, cold? The three stages of a bad cold are: first, chicken milk, second, severe bird disease, and third, watery abdomen.

In the cold season, chicks can be hatched; Falcons such as eagles are in a state of strong predation ability, hovering in the air to find food to supplement their body energy to resist the cold; In the last five days of the year, the ice in the water has frozen to the center of the water, and it is the thickest and strongest.

The three waiting periods of severe cold are divided into: the day of severe cold, the day of severe cold, the day when vultures are seriously ill, and the day of Shui Ze. In other words, every five days is a wait. For example, the new calendar time of the 2022 Great Cold is 65438+1October 20th, 65438+1October 20th ~ 24th, 65438+1October 25th ~ 29th, and 65438+1October.

Waiting for chicken milk: incubating chicks.

Secondary syndrome bird disease: birds such as eagles are in a state of strong predation ability, hovering in the air to find food to supplement energy to resist the cold.

Three times, water moistens the abdomen: in the last five days of the year, the ice in the water has frozen to the center of the water, and it is the strongest and thickest.

What is the solar term of the great cold? The Great Cold is the sixth solar term in winter and the last solar term among the 24 solar terms. Fighting refers to ugliness; The longitude of the sun reaches 300; Celebrate every year on Gregorian calendar 65438+1October 202 1.

Great cold refers to extremely cold weather. Great cold is a solar term that indicates the degree of cold weather from March 9 to April 9, just like slight cold. At this time, the cold wave frequently goes south, which is the coldest period of the year.

Quote the "Three Rites and Righteousness Sect" in "A General Examination of Giving Time" to explain: Great cold is moderate, and the upper surface is slight cold, so it is called great cold ... The extreme of cold is called great cold. There is also a folk saying: slight cold and severe cold, no wind and no cold. , all reflect the cold of the great cold.

Great cold refers to extremely cold weather. Although the winter solstice solar terms are the lowest in the northern hemisphere, the coldest time in a year is the slight cold and severe cold solar terms after the winter solstice solar terms, especially the severe cold solar terms; 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, with the lowest temperature during the severe cold solar term, which is the coldest solar term in a year. Because China has a vast territory and a large span between the north and the south, the climate between the north and the south is quite different. According to China's long-term meteorological records, there is no slight cold in the great cold solar terms in the northern region; But for most parts of the south, the coldest is the great cold solar term.
