The last volt is the last of the three volts, which is usually the hottest time of the year. Although the solar term in beginning of autumn is before the last day of the solar term, the last day of the solar term is still the period with the highest temperature, the highest humidity and the hottest weather in a year. During this period, the daily temperature may be high and the night temperature may be relatively low. In addition, after the end of the world, the weather is getting colder and colder, colder in the morning and evening, and still hotter at noon.
It won't get cold immediately after beginning of autumn. If you want to make it cold, it will take at least half a month to a month, because autumn begins in the last few days of the dog days when the festival is held on August 7 or 8 of the Gregorian calendar every year, and the weather will obviously get cold after the last few days.
The last stage refers to the day from the first Geng Day after beginning of autumn to the day before the second Geng Day after beginning of autumn, *** 10. The last volt is the last volt of the dog days, commonly known as the autumn tiger. The last few days are cooler in the morning and evening, and the sunshine is still strong during the day. But if there is an autumn tiger, it will delay the hot time. However, whether beginning of autumn is cool after autumn or after autumn, it can be clearly said that it will be even cooler after autumn.
Climatic characteristics of autumn tigers;
Although the temperature has dropped since beginning of autumn, it doesn't mean that autumn is coming. The division of climatic seasons should be based on the "average temperature", that is, the local average temperature is below 22℃ for five consecutive days, which is the real autumn.
China is a vast country. Although the climate varies from place to place, most areas have not yet entered the autumn climate, and the last days of dog days are still the third day after beginning of autumn. Especially in the south of China, this solar term is still a hot summer. At the same time, with the typhoon and rainy season gradually away, the temperature is even hotter, so the period from beginning of autumn to the autumnal equinox is called "long summer".
What is really cool is generally after the Millennium solar terms. The watershed of summer heat is in autumn, not at the turn of summer and autumn. In autumn, music is mainly divided into two stages. The first stage is called early autumn, which is mainly sultry. In the second stage, when autumn begins to get hot, it is often dry and cool, which is a season of alternating hot and cold in summer.
