2. Winter in astronomy: Winter is the solar term in beginning of winter. From beginning of winter's point of view, "Li" also means the beginning, so beginning of winter is the beginning of winter. At this time, except for some areas in the north, it is still winter, and many places in the south are still autumn scenery, where the temperature is neither high nor low, and it is refreshing and comfortable.

As far as the south China coast is concerned, the early winter is still a crisp autumn scene, even a little hot. This "winter" is not "winter" On the contrary, in the northeast and northwest, it is already a snowy scene, which naturally belongs to winter. So in order to meet the actual situation, there is a second winter standard.

According to this standard, the area north of Huaihe River in Qinling Mountains in China generally reached the standard in 1 1 and 65438+February, and some areas south of Huaihe River also reached the standard, but less. In Hainan and beginning of winter, Guangdong, it was definitely not up to standard.
