Why is it still very hot after beginning of autumn? How to distinguish autumn between men and women? How much longer can it be hot?

In the impression of many friends, after beginning of autumn, the hot weather in summer gradually faded, and the crisp weather in autumn is coming.

However, contrary to expectations, beginning of autumn is not equal to autumn. In many years, after beginning of autumn, the weather will continue to be hot, and the temperature in some areas will even be higher than before beginning of autumn.

This year (2022), many friends have the feeling that beginning of autumn has passed, but the hot weather is still unabated. In the eastern part of Henan where the author is located, the highest temperature during the day has reached 39 degrees. According to the weather forecast, the highest temperature in other areas has exceeded 40 degrees.

In this case, many friends will ask, why is beginning of autumn so hot? What does it mean that people divide beginning of autumn into "public autumn" and "mother autumn"? In this article, the author will talk about these questions in detail, and everyone will have answers after reading them.

Autumn has begun. Why is it still so hot?

Although beginning of autumn solar term is the first solar term in autumn, it doesn't mean that the hot weather will end after beginning of autumn, because beginning of autumn is still in dog days, and the next solar term after beginning of autumn is summer, which is commonly known as "midsummer", that is, the temperature will drop obviously after going out in summer.

Take this year (2022) as an example. August 7th is beginning of autumn, which is within the dog days, and it is still in the middle of the dog days. As the saying goes, "It's hot in the dog days and cold in the March 9th". The hottest period in a year is the dog days, which are divided into three days: the beginning, the middle and the end. The hottest period in the dog days is the middle of the dog days.

This year, the dog days are "super long" for 40 days (20 days for middle lying), from July 16 to August 24, and the middle lying time is from July 26 to August 14.

In other words, half of the solar terms in beginning of autumn are in the middle and half are at the end, which is a very high temperature period.

Therefore, although beginning of autumn has arrived this year, the hot weather in many places continues.

What is an autumn tiger?

A friend asked, does the hot weather after beginning of autumn belong to the autumn tiger? As the name implies, it belongs to the category of "autumn tiger".

Autumn tiger is actually a folk saying, which is a common name for the hot weather that continues to appear after the autumn.

From the meteorological point of view, it refers to the short-term weather above 35℃, mainly in August-September.

As for the cause of the "autumn tiger", according to the professional's explanation, the western Pacific subtropical high that controlled China in autumn gradually moved southward, but it moved northward. Under the control of this high pressure, today is a sunny day with strong sunshine and rising temperature.

"Autumn Tiger" does not appear every year, and its duration is different. Some years "autumn tiger" can last for ten days and a half months, and some years can last for more than a month.

The high temperature weather after beginning of autumn this year can basically explain the appearance of "autumn tiger".

What do you mean by Gongqiu and Muqiu?

Gongqiu and Muqiu are folk sayings. Beginning of autumn is divided into men and women for three reasons. Among them, the most popular is the beginning of autumn season in the lunar calendar. If the lunar calendar in beginning of autumn is in June, it belongs to "public autumn", and if the lunar calendar is in July, it belongs to "mother autumn".

This year (2022), the 10th day of the seventh lunar month in beginning of autumn falls in July, so this year beginning of autumn belongs to "Mother's Autumn".

There is also the single and double lunar calendar time in beginning of autumn, or the single and double determination. If it is odd, it belongs to "public autumn"; if it is even, it belongs to "mother autumn".

According to this method, July 10 in beginning of autumn this year is even, so it is still "beginning of autumn".

There is a folk proverb that "autumn is cool in the public, autumn in the mother is fierce" and "autumn in the public throws fans, autumn in the mother kills cows", all of which mean that if beginning of autumn is "autumn in the mother", the temperature will continue to be high after beginning of autumn, and the temperature in many places this year also conforms to this statement.

How long will the hot weather last?
