What are the characteristics of slight cold solar terms?

The Gregorian calendar has passed in 2020, which means that the lunar calendar is coming to an end in 2020. Before the end of the lunar calendar in 2020, we will also experience slight cold and severe cold, which represent the two coldest solar terms in a year. Among them, the slight cold solar term is tomorrow, that is, 202 1 year 1 day. So, what are the characteristics of the slight cold solar terms? What should I pay attention to? Let's have a look!

Characteristics of slight cold solar terms

The slight cold solar term is characterized by entering the coldest day of the year. Slight cold is the 23rd solar term among the 24 solar terms, the 5th solar term in winter, the end of the second month of the dry calendar and the beginning of the ugly month. The solar longitude is 285, and the solar calendar is 65438+1October 5-7 every year.

Cold air is cold for a long time, and slight cold means that the weather is cold but not extreme. Like severe cold, mild heat, severe heat and intense heat, it is a solar term indicating temperature change. The slight cold solar term is characterized by cold, but it is not extremely cold.

After the winter solstice, the cold air frequently goes south, and the temperature continues to drop, and the temperature drops to the lowest during the slight cold and severe cold in a year. There is a folk saying that "it's 239 when it's cold, and it's shivering with cold", which shows the cold degree of solar terms.

In the slight cold season, the direct point of the sun is still in the southern hemisphere, and the heat in the northern hemisphere is still in a state of loss. The heat absorbed during the day is still less than the heat released at night, so the temperature in the northern hemisphere continues to decrease.

According to China's long-term meteorological records, the slight cold solar terms in the north are colder than the severe cold solar terms, and there is a saying in the north that "slight cold is better than severe cold"; However, for most parts of the south, the lowest temperature in the whole year will still appear in the great cold solar terms.
