What are the characteristics of the great cold solar terms? How does the weather change in the cold season?

First, the characteristics of the great cold solar term, the cold wave frequently goes south, which is the cold period in most parts of China in a year. The wind is strong, the temperature is low, and the snow on the ground does not melt, showing a cold scene of ice and snow. The poem says, "The wax trees are shady and the mountains are bright, and the north wind roars the three rivers alone." The old farmer still likes Gao Xue, which will taste like wheat and fruit in the coming year. "The Great Cold is the last of the 24 solar terms in China. After the severe cold, beginning of spring will usher in a new year's solar cycle. In ancient China, the Great Cold was divided into three stages: "One stage is chicken milk; Second, the symptoms of bird disease; Three times, water is strong. "That is to say, you can hatch chickens in the cold solar terms. 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 strongest and thickest. Children can enjoy skating on the river.

Second, how does the weather change during the severe cold season? The atmospheric circulation is relatively stable, and the circulation adjustment period 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. Under the influence of the northwest wind flow control and the constantly supplemented cold air, there will be sustained low temperature in China. 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. At the same time, the severe cold is the period with the least rain in a year. During the cold solar term all the year round, the rainfall in most parts of the south only increased slightly compared with the previous period, with 5 ~10mm in most parts of the south and only1~ 5mm in the mountainous areas of the northwest plateau. At the same time, cold waves frequently go south during this period, and most parts of our country are quite cold in a year.
