What are the climatic characteristics of solar terms in beginning of winter and beginning of winter?

1. Climatic characteristics of solar terms in beginning of winter: the temperature difference between north and south is widening. China has a vast territory, and the north and south span dozens of latitudes, so there is a temperature difference between the north and the south. However, after winter, the temperature difference between the north and the south widened. 1 1 In recent months, the average temperature in most parts of the Qinghai-Tibet Plateau, Inner Mongolia and northern Heilongjiang has reached about-10℃. The temperature difference between Mohe in the northernmost part and Haikou in Hainan Province can reach 30℃-50℃. Many places in the north have been dry, everything is withered, and the cold is pressing; South China is still green mountains and green waters, birds and flowers are fragrant, warm and pleasant.

2. Climatic characteristics of solar terms in beginning of winter: tropical cyclones are at the end of the road. 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, tropical cyclones are more active, and if meridional circulation prevails in mid-latitude, that is, cold air is stronger, typhoons are not easy to occur.

3. Climatic characteristics of solar terms in beginning of winter, autumn and summer in south and north China. 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. 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.
