Meteorological changes in early winter season

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 in 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.
