How does the temperature of the slight cold solar term change?

It is very cold, but it is not particularly cold.

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.

Phenological characteristics of slight cold solar terms

The ancients in our country divided the fifteen days of the slight cold season into three periods: one was waiting for Yanbei Township; Second, magpies began to build nests; Three wait for the pheasant to start. Although the temperature is low in the slight cold season, the yang has begun to sprout, and the geese move north along the yin and yang.

At this time, magpies can be seen everywhere in the north. They feel the sun be the spirit and start to build nests. The word "pheasant" means singing, and pheasant sensed Yang's growth and began to sing.
