After the Beginning of Autumn, does it mean it is already autumn?

The beginning of autumn just means the beginning of autumn. The heat of summer has not completely ended yet. The heat will not dissipate until the end of summer and the weather will slowly turn cooler. Based on their experience over the years, Han folk have concluded the saying of the Twenty-Four Autumn Tigers, which is widely circulated. This means that if it does not rain on the day of Beginning of Autumn every year, then the twenty-four days after Beginning of Autumn will also be very hot. .

Autumn tiger weather will appear after the beginning of autumn. Autumn tiger refers to the short-term hot weather after the beginning of autumn in my country. It usually occurs at the turn of August and September and lasts for about 7-15 days.

The reason for the formation of autumn tiger is that the western Pacific subtropical high pressure that controls my country gradually moves southward in autumn, but then moves northward. Under the control of this high pressure, it is sunny and cloudy, with strong insolation and rising temperatures. This kind of returning hot weather is called "Old Woman Summer" weather in Europe and "Indian Summer" weather in North America.

Due to the vast territory of our country, the performance of "autumn tigers" is slightly different. For example, the autumn tigers in South China arrive later than those in the Yangtze River Basin, and are generally delayed by 2-4 seasons. In addition, the period of tiger control in autumn varies from half a month to two months each year.
