One summer in 24 solar terms has come, but it's still hot at 2 o'clock. What is the reason?

In the southern region under its control, people who feel a little cool in autumn often feel the high temperature climate again in late summer, which is a veritable "autumn tiger". In China, autumn tiger refers to the short-term high temperature weather after beginning of autumn (around August 8).

It usually occurs at the turn of August and September and lasts about 7 15 days. The reason for the formation of autumn tiger is that the western Pacific subtropical high that controls China gradually moves southward in autumn, but moves northward. Under the control of this high pressure, it is cloudy in sunny days, with strong solar radiation and rising temperature. This regenerative weather is called "old woman summer" weather in Europe and "Indian summer" weather in North America. Due to the vast territory of China, the performance of "Autumn Tiger" is slightly different. For example, the autumn tiger in South China is later than the autumn tiger in the Yangtze River valley, and it is generally delayed by 24 solar terms.

In addition, the prevention and control time of autumn tigers is long and short every year, ranging from half a month to two months; Sometimes the autumn tiger comes and goes, and then goes back. "Autumn Tiger" weather, although the temperature is high, but generally speaking, the air is dry and sunny, it will not be very hot in the morning and evening, and it will not be too hot to breathe.
