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, but when plum blossoms are in full bloom.

The slight cold solar term is characterized by cold, but it is not extremely cold.

Meteorological changes and phenological phenomena of slight cold;

Meteorological changes of slight cold;

The weather characteristics of slight cold are: it gets cold, but it is not cold yet. 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.

Slight cold phenomenon:

In ancient China, the "slight cold" was divided into three stages: "First-class Yanbei Township, second-class magpies started their nests, and third-class pheasants started their lives." The ancients believed that the geese among migratory birds migrated along the yin and yang, and at this time, the yang had moved, so the geese began to migrate north.

At this time, magpies can be seen everywhere in the north, feeling the yang and starting to build nests; The word "pheasant" means singing. As April 9th approaches, pheasants can sing.
