What are the characteristics of the climate of solar terms in beginning of winter?

Cold air appears frequently, and cooling has become the normal state of this season, so we must pay attention to keeping warm.

The arrival of solar terms in beginning of winter means the official start of winter. This climate is characterized by an increase in the north wind and a decrease in the temperature. Astronomy regards "beginning of winter" as the beginning of winter, but according to the division of climatology, China will postpone winter for about 20 days. In early winter, the sun has reached 225 degrees, and the amount of solar radiation in the northern hemisphere is getting less and less. However, due to the storage of heat and some energy on the surface in the second half of this year, it is generally not too cold, but the temperature is gradually decreasing. When there is no wind on a sunny day, sunny, warm and comfortable "Xiaoyangchun" weather often appears in October.

In northern South China during beginning of winter, even if the cold wind sweeps away, the temperature will rise rapidly. When there is no wind on a sunny day, it is often said that "October is sunny and there is no wind to warm". It is often winter here in 65438+February. In South China, Taiwan Province Province and Hainan Island to the south, 165438+ 10 has not yet entered winter. However, the temperature in June 5438+065438+ 10 is not very high, and the highest temperature is generally below 30℃. In addition, it is not excluded that there is a strong cooling due to the influence of strong cold air, but it is rare in recent years.
