Is it air-cooled after the first frost?

It will be cold after the first frost, and the temperature will be colder than the solar terms of the white dew and cold dew before the first frost. At this time, the cold air will become active, and there will be strong winds and cool weather in many areas.

The "first frost" solar term is characterized by cold weather in the morning and evening, hot weather at noon, large temperature difference between day and night, and obvious autumn dryness. On the national average, the first frost is the season with the largest temperature difference between day and night in a year. After entering the first first frost solar term, the cold air activities affecting our country became more and more frequent, and the temperature difference between day and night increased rapidly. Especially in Jiangnan and South China, the temperature fluctuation is more and more obvious; Some areas in northwest and northeast China have shown the scene of "cold wind and fallen leaves" in early winter.

During the first frost, it usually lasts from late June 10 to early October110. With the dry and cold air gradually dominating the whole country, the warm and humid air is marginalized, and many weather with the characteristics of summer and early autumn exits, so the weather is relatively simple. Before and after beginning of winter, there were often strong winds and cool weather, and some places entered winter in a short time.
