Foreword: The beginning of autumn next month: what time is the beginning of autumn this year? How long will it be hot? The beginning of autumn is a foreshadowing
Year after year, time and all things continue to advance in the alternation of the 24 solar terms, and after the Great Heat solar term, it means that the summer is coming to an end, and autumn will soon begin. Between August 7th and 9th every year, we will usher in the first solar term of autumn - "Beginning of Autumn", as early as the ancient book of the Western Han Dynasty "Huainanzi" has recorded that "the (lunar calendar) July Festival is the beginning of autumn".
There are two solar terms in the seventh month of the lunar calendar, which are the beginning of autumn and the beginning of summer, and they are also the final stage of the dog days. Among them, the beginning of the autumn solar term was annotated in the Yuan Dynasty work "Seventy-two Candidate Explanations of the Moon Order" as, "The beginning of autumn, the seventh month, the word interpretation sees spring." Autumn, squeezing also. Things are here and constricted, and the cool breeze is coming". The "autumn" of the beginning of autumn has the meaning of convergence, and then the autumn wind arrives, and the weather will become cooler and cooler.
Autumn is the harvest season, which is related to whether the hard work of the year can be rewarded as scheduled, so as the "four festivals" (the beginning of spring, the beginning of summer, the beginning of autumn, the beginning of winter) the beginning of autumn has always been one of the most important solar terms in the hearts of the ancients. The beginning of autumn belongs to the transition period between summer and autumn, and the weather will not get cooler immediately, but will have a gradual process.
The ancients generally made predictions based on the characteristics of the Autumn Festival of the year, and how long it would be hot? Will the following winter be cold? Is the year good or bad? So how exactly did the ancients predict it? It's the beginning of autumn next month, what time is the beginning of autumn this year? How long will it be hot? There is a foreshadowing on the day of the beginning of autumn, let's find out together.
In the ancient almanac, it is believed that "the bucket refers to the southwest dimension for the beginning of autumn", and when the handle of the Big Dipper in the sky points to the southwest direction and the sun arrives at 135 degrees of ecliptic longitude, it is the time of the year when the autumn festival is neutral.
Based on the observation of celestial phenomena and the judgment of the laws of the sun's movement, we can get the specific time of the beginning of autumn this year: 2024-08-07 08:09:01 Beginning of autumn. Of course, there is a simpler way, each of the 24 solar terms is about 15 days apart, the previous solar term of the beginning of autumn is the great heat, this year's summer festival is July 22, and after counting 15 days, it happens to be the beginning of the autumn festival on August 7.
The beginning of autumn means that autumn has begun, but it does not mean that the weather is starting to get cooler, these are two different concepts. As for how long it will be hot this year, we can look at it from two aspects.
First of all, let's look at the schedule of dog days, the dog days in 2024 start on July 15, enter the middle of the dog days on July 25, and do not come out until August 24. Dog days are the hottest time of the year, and the weather is sure to be hot and not as cool as it gets. The beginning of autumn is on August 7 this year, and there is still a long time before the beginning of the autumn, so it is impossible to get cool as soon as you enter the beginning of autumn.
Second, we need to judge the possibility of the emergence of the "Autumn Tiger". What is an "autumn tiger"? It describes that the weather becomes cooler after the volcant, but then there is a high temperature weather above 35 °C, generally from the end of August to September, this time is cooler in the morning and evening, but it is still very hot at noon, and the temperature difference is relatively large.
"Autumn Tiger" does not appear every year, as for whether it comes or not, the ancients generally looked at the situation on the day of the Autumn Festival, including "Autumn Bao Fu or Fu Bao Autumn", "Early Autumn or Late Autumn", "Male Autumn or Female Autumn" and so on. In order to help you better understand, I will explain each of them with three agricultural proverbs as representatives.
The three dog days are composed of the beginning, the middle and the end, and the time of the beginning and autumn festival is relatively close to the end of the festival every year, and this agricultural proverb says that the morning and evening order of the beginning of autumn and the end of the three dogs.
If the beginning of autumn arrives earlier than the end of the year, it belongs to the "autumn package", indicating that the weather will soon become cooler; If the beginning of autumn arrives after the end of the autumn season (including the day of entering the end of the autumn season), it is considered "Fubao Autumn", which indicates that the weather will still be very hot after the beginning of autumn and will continue for a long time.
This year, the date of the beginning of autumn is August 7, and the beginning of the end of the autumn is August 14, the beginning of the autumn is earlier than the end of the autumn belongs to the "Fu Bao Qiu", in the opinion of the ancients, the weather will be cooler after the beginning of the autumn in this case.
This agricultural proverb comes from the agricultural book "Four People's Moon Order" written by Cui Wei in the late Eastern Han Dynasty, which divides the beginning of autumn into early autumn and late autumn.
"Chao" refers to the morning, and "Chao Liqiu" as the name suggests is the beginning of autumn in the morning, which corresponds to "cold and fluttering", indicating that the weather will not be hot for too long this year, and it will soon become cooler after the beginning of autumn. "Night Beginning of Autumn" refers to the beginning of autumn at night, which can also be understood as the beginning of autumn after 1 o'clock in the afternoon, because the ancients generally used "noon" as the dividing point between morning and evening, and the beginning of autumn at this time means that it will be hot for a long time later.
The specific time of the beginning of autumn this year is about 8 o'clock in the morning, which is "the beginning of autumn, cold and fluttering", so it seems that the weather after the beginning of autumn should not be hot for too long, and there will be a cooling process soon, which is consistent with the "autumn baofu" climate phenomenon mentioned above.
This agricultural proverb is very vivid, the beginning of the autumn personification into the male autumn and the female autumn, the ancients mainly look at the beginning of the autumn festival on the day of the lunar calendar is a singular or even number to identify the male and female. If it is an odd number, a single public is a public autumn. On the contrary, if it is an even number, the double mother is the mother autumn.
People often use the term "tigress" to describe menacing, which is consistent with the meaning of "tigress". The ancients believed that if the beginning of autumn was a public autumn of that year, it would give people a cooler feeling. But if it is the mother autumn, there is usually an illusion of getting cooler, and then the weather will get hotter again, which actually corresponds to the "autumn tiger" climate phenomenon.
The date of this year's Autumn Festival is the fourth day of the seventh month of the lunar calendar, and the "four" is an even number belonging to the mother autumn, which corresponds to the "mother autumn fierce", indicating that the possibility of "autumn tiger" appearing after the autumn of this year is relatively large.
Speaking of which, you may feel a little contradictory, because the first two sentences clearly say that "Autumn Baofu" and "Chao Liqiu" are cooler, and why it gets hot when it comes to "Mother Fu", which is going to talk about what "Autumn Tiger" is all about.
In meteorology, "autumn tiger" refers to the hot weather that reappears after the beginning of autumn or the summer heat, and the key lies in the four words "re-emerge". It means that the weather will go through the process of first turning from hot to cool, and then from cool to hot, and it feels like the hot day is over, but I didn't expect it to come back again not long after, and the main climate characteristics are cool in the morning and evening, and hot at noon.
Therefore, we can draw a conclusion that "autumn baofu" and "morning and autumn" mean that the weather will slowly become cooler after the beginning of autumn, and it will no longer be as hot as before, but after the weather is cool for a while, the hot weather may come back again, and at this time it belongs to the characteristics of "mother ambush".
So what should we do to prepare? There may be hot weather after the weather cools down this year, don't rush to put away your summer clothes, and be alert to the appearance of "autumn tigers", remember to add clothes in the morning and evening, so as to avoid affecting daily life due to hot and cold weather.
