What is the general temperature of light snow solar terms?

The temperature in the light snow stage is lower than that in winter. Entering this solar term, the northeast wind in China began to become a frequent visitor, and the temperature gradually dropped below 0℃, but the earth was not too cold. Although it began to snow, the amount of snow was not large, so it was called light snow. At this time, the yang drops and the yin rises, which leads to the impassability of heaven and earth, the incoherence of yin and yang, the loss of vitality of everything, and the occlusion of heaven and earth into the severe winter. The first snow will appear in the area north of the Yellow River, reminding people that it is time to keep out the cold and keep warm. Generally speaking, the average maximum temperature in North China is 15 degrees, and the average minimum temperature is 5 degrees. Light snow solar terms, the northern part of the southern region began to enter winter. Due to the barrier of Qinling Mountain and Daba Mountain in the north, the invasion of cold air is blocked and the cold wave is weakened. The "warm winter" in South China is remarkable. The number of snowfall days in the whole year is mostly less than 5 days, which is much less than that in the middle and lower reaches of the Yangtze River at the same latitude. There is little possibility of snow before the heavy snow. Because the surface temperature in South China is often above 0℃ in winter, it is more difficult to snow than to snow. In the cold northwest plateau, it usually begins to snow all the year round 10. The number of snowfall days in the northwest of the plateau can reach more than 60 days a year, and snowfall is possible in some alpine regions all year round.
