Is it cool sooner or later after the start of autumn? In fact, the early or late of the start of autumn has little to do with the hot weather. Whether there will be hot weather in the future depends on the subtropical high and cold air. The main factors affecting the weather are the general circulation, solar radiation, underlying surface conditions and human activities. There is no scientific basis for the statement that the early or late of the start of autumn affects the cold and warm weather.
How long it will be cool after the beginning of autumn there is a folk saying that "cool wind will arrive on the third day of the beginning of autumn". However, most areas are still dominated by sunny and cloudy weather after the beginning of autumn. The rainfall weather is not obvious, the temperature can still reach 31-33 ℃, the daily average temperature is still high, and the weather is still "sultry".

There will be autumn tiger weather after the beginning of autumn. Autumn tiger is a short-term hot weather after the beginning of autumn. It usually occurs at the turn of August and September and lasts for about 7-15 days. The reason for the formation of the autumn tiger is that the subtropical high in the Western Pacific Ocean, which controls China, gradually moves southward in autumn, but then moves northward. Under the control of the high, there are clear clouds, strong solar radiation and rising temperature. This kind of regenerative weather is called "old woman summer" in Europe and "Indian summer" in North America. (this article is exclusively compiled by WYH, editor of sihai.com.

Because of China's vast territory, the performance of "autumn tiger" is slightly different. For example, the autumn tiger in South China comes later than that in the Yangtze River Basin, generally delaying 2-4 seasons. In addition, the control time of the autumn tiger varies from half a month to two months every year; sometimes the autumn Tiger comes, goes and looks back. Although the temperature of autumn tiger is high, the air is dry and sunny in general. It's not very hot sooner or later, so it won't be too hot to breathe.

But there will still be a temperature of about 35 ℃ during the day, and sometimes it will still feel sultry. The real cool usually comes around the White Dew in early September. This is relative to the weather in the south. In fact, it's hot for several days every year in the beginning of autumn, but the daily temperature range is increasing. It's warm in the day and cool in the night. This temperature environment is very conducive to the production and accumulation of dry matter in agricultural objects. Other crops are mostly like this, that is, people often say: 'how can crops mature when it's not hot'! Actually, the beginning of autumn doesn't mean that the weather will be cool.
