Climatic characteristics of slight cold solar terms

The climate characteristic of the slight cold solar term is that the weather is getting colder and colder, 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. 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.
