Whether winter is cold or not depends on which solar term.

See if beginning of winter is cold in winter, because there is a proverb: "beginning of winter is sunny and winter is sunny;" The winter rain began, a winter rain. "

"beginning of winter sunny, sunny in winter; The proverb "It rains in beginning of winter and it rains in winter" is very popular, and friends in many areas have heard of it, and it is easy to explain it literally. If that day is sunny in early winter, there will be more sunny days in winter that year. On the contrary, if that day is rainy in early winter, there will be more rainy days in winter that year.

In winter, if it is sunny, people will feel warmer, and if it rains or snows, they will feel colder. Therefore, from this proverb alone, it is sunny on the day of beginning of winter solar terms, and it is not very cold in winter, and there is not much rain and snow. On the contrary, it is rainy in early winter, so it is relatively cold and rainy in winter.

Meteorological changes in early winter;

In early winter, the sun has reached the longitude of 225 degrees, the sunshine time will continue to be shortened, the height of the sun will continue to decrease at noon, and the amount of solar radiation obtained by the northern hemisphere will be less and less, but there is still some energy due to the heat stored on the surface in the second half of this year. Because there is still "accumulated heat" on the surface, it is usually not very cold in early winter, and the real cold is after the winter solstice. Due to the large span between north and south in China and the great climate difference between north and south, the winter with this climatic significance is obviously late for some parts of China.

After winter, the climate changes from dry autumn to rainy and cold winter. Beginning of winter —— In the southern part of Xiaoxue (a small spring in October), from beginning of winter to Xiaoxue, sunny, warm and comfortable "small spring" weather often appears. There is a folk saying that "it's sunny in October", which means "it's warm in August and warm in September, and it's sunny in October". It is generally not too cold in early winter in the south. With the passage of time, after the winter solstice, cold air frequently goes south, and the temperature gradually drops.
