Weather characteristics in early winter

The weather features in early winter are: gradually cooling temperature, cold wave, dry weather, increasing rain and snow, tropical cyclone, strong typhoon, south and north of South China, autumn and summer, etc.

First, the temperature is getting cold.

During the beginning of winter season, the temperature in most parts of China began to drop gradually. The northern region has already felt the chill, and the southern region has gradually turned cold.

Second, the impact of cold wave

Since winter, the frequency of cold wave has gradually increased, especially in the northern region. Cold wave attacks are often accompanied by strong winds, heavy rains and obvious cooling.

Third, the weather is dry.

After winter, the humidity in many areas began to gradually decrease and the air became relatively dry.

Fourth, the rainy and snowy weather has increased.

With the arrival of beginning of winter, the rainy and snowy weather is increasing gradually, especially in the north of China. The drop in temperature leads to the change of precipitation form, and rain may gradually turn into snow, which will have a certain impact on traffic.

Five, tropical cyclones, a spent force

On average, two or three tropical cyclones are generated 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.

Sixth, South China, autumn, winter and summer.

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.
