How to say the slight cold solar terms?

In northern China, there is a saying that "mild cold is better than severe cold, which is common but not rare".

It means that the slight cold solar terms are colder than the severe cold solar terms, which is not unusual. Slight cold usually occurs from February 9th to March 9th, which is the coldest time of the year in northern China. After the slight cold, the temperature of heavy cold rose slightly.

The coldest in southern China is in April and September, which is colder than in March and September. In April and September, it was the great cold solar term, and the great cold in the southern region was colder than the slight cold. 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.

During the slight cold season, most parts of China have entered a severe cold period, with frozen soil and rivers frozen. In addition, the cold air in the north keeps going south and the weather is cold. People call it "counting nine cold days"

Although the south of China is not as cold as the north, the temperature drops obviously. The coldest time in the south is slight cold and severe cold, between rain and fright. It is dry and cold when it is a little cold, and it is wet and cold after the rain.

Weather characteristics of slight cold

It's getting cold, but it's not. 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.

The climate in south and north of China is quite different. According to China's long-term meteorological records, the slight cold solar terms in the northern region are colder than the severe cold solar terms; But for most parts of the south, the big cold solar terms are colder than the small ones.

During the slight cold solar term, the East Asian trough developed the strongest and most stable, the Mongolian cold high and Aleutian low also reached the strongest and most stable, and the ridge scale of the westerly trough reached the maximum, which matched the strongest westerly intensity. The cooling process of cold air is frequent in the slight cold season, but few of them reach the cold wave standard.
