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 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.

In the southern region, sunny, warm and comfortable "Xiaoyangchun" weather often occurs from beginning of winter to Xiaoxue. 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.

Rain and snow will cool down in most parts of northern China in early winter. The first snow in parts of North China often falls at this time. In the northeast and northwest regions, it is already a scene of heavy snow, especially in the northeast Heilongjiang region, which is extremely cold and has already presented a scene of winter long before the arrival of beginning of winter. The continuous exertion of cold air has also caused the northern region to enter the heating season.
