What are the characteristics of the cold climate?

The Gregorian calendar is coming to an end in 2020, but the last solar term in the 24 solar terms of the lunar calendar in 2020, the Great Cold, has not yet arrived, which means there is still a period of time before the end of the lunar calendar in 2020. The arrival of the great cold solar terms means the arrival of the coldest period. So, what are the main characteristics of the climate of the great cold solar terms? Let's take a look at Bian Xiao!

Characteristics of severe cold solar terms

The great cold solar term is characterized by cold weather and the least rain. Great cold, like slight cold, is also a solar term indicating the cold weather. Great cold is the coldest solar term in a year. 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, April and September are the coldest, so the big cold solar terms are colder than the small ones.

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.

As soon as the great cold is over, a new cycle begins, which means that winter goes and spring comes. In some places in the south of China, especially in rural areas, there are many important folk customs from the Great Cold to beginning of spring, such as rich food, offering sacrifices to stoves and New Year's Eve.

Tail luxury food is also called "making teeth" and "making luxury food". There is a folk custom of "eating tail teeth" after eating luxury food. The popular "annual meeting" at the end of modern enterprises is developed from abundant food.
