Will it be cold after winter this year?

The weather will get cold after the start of winter in 2023.

Beginning of winter marks the official entry of winter in China, so it will get colder and colder after beginning of winter, but the temperature in different regions is different. In early winter, the height of the sun in the northern hemisphere becomes smaller, the daylight time becomes shorter, and the amount of solar radiation obtained by the northern hemisphere becomes less and less. However, due to the heat stored on the surface in the second half of this year, it is generally not too cold, but the temperature is gradually decreasing. In some areas in the south, sunny, warm and comfortable October "Xiaoyangchun" weather often appears when there is no wind. In the north, the weather is very cold in early winter.

In winter, northeast winds and north winds prevail, and the temperature drops gradually. Because there is still some energy in the heat stored on the surface, it is generally not very cold in early winter. As time goes by, strong cold air frequently goes south and crosses Nanling, and the weather is getting colder and colder. In the north, it is already very cold before winter begins.

The Historical Origin of beginning of winter

Beginning of winter is the first solar term in winter, representing the beginning of winter. It's early March in winter. Beginning of winter, beginning of spring, Changsha and beginning of autumn are collectively called "Li Si". Spring is planted in Xia Yun and harvested in autumn and stored in winter. Everything germinates in spring, grows in summer and harvests in autumn, and enters the state of fallow storage in winter. Beginning of winter means that life begins to close, everything enters a state of rest and collection, and plants wither. For example, "The Book of Filial Piety" says: What the bucket refers to is the beginning of winter and the end of winter, and everything is collected.

As for the division time of the four seasons, China traditionally takes "Li Si" (beginning of spring, Changchun, beginning of autumn and beginning of winter) among the "24 solar terms" as the beginning of the four seasons, and "Bi Fen" (vernal equinox and autumnal equinox) and "Two Fingers" (summer solstice and winter solstice) as the midpoint of the four seasons, which has obvious astronomical significance.

The change throughout the year is a continuous process. It is also a process of yin-yang transformation, from one side to the other, quantitative change produces qualitative change. In this gradual process, beginning of spring, Changxia, beginning of autumn and beginning of winter, also known as "Sili", are the opening of the season and the turning point in the 24 solar terms.
