enters November. The temperature changes subtly and the cold air is ready to move. People sometimes call it "season change month", and the beginning of winter solar term comes on November 7 or 8 every year. In custom, Chinese people also take the beginning of winter as the beginning of winter. So whether the beginning of winter is a season change or not, let the old yellow calendar introduce it to you.

立冬是不是换季

in November, people ushered in the beginning of winter. Usually, people often think that the beginning of winter is the beginning of winter, but according to astronomy experts, the "beginning of winter" in the lunar calendar is not the beginning of winter in meteorology. It will take a while to really change the season.

and

experts say that the beginning of winter and the beginning of winter are not the same thing. Lidong is just an astronomical saying, which means that the sun comes to 225 ° of the Yellow meridian. Lidong indicates the change of solar terms. The time of each year is relatively fixed, both on November 7 or 8. The annual climate conditions are different, and there are great differences in the morning and evening of winter. The time difference can reach two or three weeks. It is often necessary to wait for more cold air and the temperature drops to a certain extent before we can say that the real winter comes.

and

are divided into four seasons according to climatology. Winter is when the average temperature drops below 10 ℃ in the next half year (5 days). Mohe in the northernmost part of China and the area north of Daxinganling have already entered a long winter in early September; In the first and middle of October, some areas in the northwest and northeast successively entered the threshold of winter. The capital of

and

, Beijing, is already a scene of winter in late October; From the end of October to the beginning of November, winter comes to the south of Northeast China, North China and Huang Huai; During the light snow solar term at the end of November, the scene of winter can be seen in the Yangtze River Basin; In early December, winter finally approached the Wuyi Mountains and the north slope of Nanling in the north of Guangdong and Guangxi.

and

experts also pointed out that the lowest temperature usually occurs before and after sunrise, but after the autumn equinox and before the winter solstice, the sunrise time will be later and later. Therefore, the occurrence time of the minimum temperature will also be postponed, getting closer and closer to the time of going out to work. Therefore, in November, I believe everyone will soon feel cold, especially those who go out early and return late.
