What does the slight cold solar term mean?

The so-called slight cold means that the weather is cold, but it has not reached the extreme.

When the sun meridian reaches 285 degrees, the slight cold solar term begins. Cold means cold, and slight cold means the degree of cold. 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.

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 the great cold rose slightly. The coldest in southern China is in April and September, which is colder than in March and September.

Agriculture:

At this time, we should continue to do a good job in the cultivation of spring flower crops, do a good job in frost prevention and moisture prevention, and strive for a bumper harvest of flowers in spring. In order to prevent snow and freezing rain from breaking fruit trees in bamboo forests, it is foggy and windy in winter, so special attention should be paid to safety in fishing and breeding operations at sea or in rivers and lakes. Monsoon climate is the main feature of China climate, which is a mixture of continental climate and maritime climate.

Judging from the seasonal distribution of precipitation, precipitation in China is mainly concentrated in summer, that is, when the southeast monsoon prevails. The northwest monsoon from Eurasia prevails in winter in China, with less water vapor content and less precipitation. Slight cold and severe cold are the two solar terms with the least precipitation in a year.
