Meteorological change

Cold dew is a solar term reflecting the characteristics of climate change. After the cold dew solar terms, the days become shorter, the nights become longer, the sunshine decreases, the hot air slowly recedes, the cold gradually increases, the temperature difference between day and night is larger, and it feels a little chilly in the morning and evening. After the cold dew, the cold air in the north has a certain influence, and most parts of China are controlled by cold high pressure, and the rainy season is over. Wan Li is clear, warm during the day and cool at night. Thunderstorms have disappeared in most parts of Chinese mainland. ?

From the climate characteristics, in the cold dew season, the autumn in the south is getting stronger, cool and cool, with little rain and dryness; The northeast and northwest regions in the north show a scene of winter, with thousands of miles of frost and snow in Wan Li, which is quite different from the autumn colors in the south.

As the direct point of the sun continues to move southward in the southern hemisphere, the angle of sunlight in the northern hemisphere begins to tilt obviously, and the solar heat received by the ground is obviously reduced compared with that in summer. The influence of cold air's sphere of influence can sometimes extend to South China.

In the cold dew season, dew increases and the temperature decreases. At this time, the temperature in most parts of South China continued to drop. The average daily temperature in South China is less than 20℃. Even in the areas along the Yangtze River, it is difficult for the temperature to rise above 30℃, while the minimum temperature can drop below 10℃. Except for a few valley lowlands, the five-day average temperature in the northwest plateau is generally lower than 10℃, and the standard of dividing the four seasons according to the "average temperature" is winter.
