What does the solstice mean in winter?
"Twenty-four solar terms" said: "In mid-November, the ultimate Tibetan gas is extremely extreme." After the winter solstice, the climate in all parts of China has entered the coldest stage, which is often called "nine cold".
Weather characteristics of winter solstice
In winter solstice, although the sun is low and the days are short, the temperature in winter solstice is not the lowest in meteorology. In fact, because there is still "accumulated heat" on the surface, it is usually not very cold before the winter solstice, and the real cold is after the winter solstice.
Because of the great difference in climate in different parts of China, this winter climate is obviously late for most parts of China. The winter solstice marks the beginning of the cold season, and people begin to count nine to calculate the cold days.
