What does the high temperature in early winter mean?

If the weather in beginning of winter is sunny and the temperature is high, it means that there is little rain and snow in winter, and it is prone to winter drought.

The ancients observed that if the solar terms in beginning of winter are sunny, it also means that there is less rain and snow in winter, which is prone to winter drought. If it rains in early winter, it will rain in winter. This is what the agricultural proverb says: "The early winter is sunny, and the winter is sunny; The winter rain began, a winter rain. "

Climatic characteristics of beginning of winter.

1, the temperature dropped obviously.

With the strengthening of cold air, the cooling trend accelerates. People are used to the coolness in the north. Since the end of 10, heating has been provided one after another, and people have shelter from the cold. For people in the middle and lower reaches of the Yangtze River in late autumn, the average temperature is generally 12℃ to 15℃.

The rain has stopped in Mao Mao. If you encounter strong cold air and move south quickly, sometimes in less than a day, the temperature can be close to 8- 10℃, or even more. But after all, after the gale, the sun shines, the cold air mass degrades rapidly, and the temperature rises rapidly. The rise of temperature and the accumulation of heat prompted the next round of cold air to bring a strong cooling.

At this time, the pleasant late autumn weather is coming to an end, and the obvious cooling makes this area enter the first frost period and the best viewing period of red leaves, and 1 1 enters the winter at the end of the year.

2, tropical cyclones, a spent force

According to statistics, there are 2-3 tropical cyclones in June165438+1October every year. In particular, cyclones generated in the northwest Pacific may develop into typhoon intensity. In the past 55 years, there have been 1 1 tropical cyclones landing in China's coastal areas in1month, mainly in Taiwan Province Province, Guangdong Province and Hainan Province. If zonal circulation prevails in mid-latitude this year, tropical cyclones will be more active. If meridional circulation prevails in mid-latitude, that is, cold air is stronger, typhoons will not occur easily.

3. It is easy to have frost and fog in winter and late autumn.

In normal years165438+1early October, frost will appear one after another from the Qinling Mountains in the north, the western and southern parts of Huanghuai, and the northern part of Jiangnan in the south. In the cold year165438+1mid-October, the first frost will also appear north of Nanling.
