At present, four seasons are often divided according to the temperature change, and the method of "weather average temperature" proposed by modern scholar Zhang Baokun is adopted. According to the four seasons divided by the weather average temperature method, the average daily temperature is equal to or lower than 10 degrees Celsius for five consecutive days, which is regarded as entering winter.

Climatic characteristics

Beginning of winter said that since then, winter has traditionally started with "beginning of winter" in 24 solar terms. "beginning of winter" refers to wind and rain, humidity, light, temperature, etc. At the turning point, the climate is gradually changing from autumn to winter. In winter, the direct point of the sun moves south to the tropic of Capricorn, and then turns back to the north.

In early winter, the sun reaches the longitude of 225 degrees, and the earth is at declination-16 19'. The height of the sun in the northern hemisphere becomes smaller, the daylight time becomes shorter, and the amount of solar radiation obtained in the northern hemisphere becomes less and less. However, there is still some energy in the heat stored on the surface in the second half of this year, so it is not very cold.

During the period of Meng Dong (winter solstice and light snow), when there is no wind, there is often sunny, warm and comfortable "Xiaoyangchun" weather, and there is a folk saying of "Xiaoyangchun in October". It is generally not very cold in early winter (Meng Dong) in some parts of the south, but with the passage of time, cold air frequently goes south and the temperature gradually drops.
