Will it get cold after the dog days?

It may not be cold in dog days, but there may be "autumn tigers" after coming out. The "autumn tiger" in meteorology refers to the weather that warms up for a short time after lodging for three days. Due to the vast territory of China, the performance of "Autumn Tiger" is slightly different. For example, the autumn tigers in South China are later than those in the Yangtze River valley, generally delayed by 2-4 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.

The reason for the autumn tiger weather is that the subtropical high withdrawn from the south is under control again, which leads to sunny weather, strong solar radiation and high temperature and hot summer weather. Although it is autumn, it is sultry. Based on many years' experience, the people have summed up 24 autumn old sayings, which are widely circulated. This means that if it doesn't rain on the day of beginning of autumn every year, it will be very hot in the twenty-four days after beginning of autumn, so it is called the twenty-four autumn tiger; If it rains that day in beginning of autumn, even if it is light rain, it is also called "Shun Qiu". There is a folk proverb: an autumn rain is followed by a cold, which means that the weather will get colder and colder after the autumn.
