What is the difference between early and late early and late early autumn?

Today is the beginning of autumn, the hot summer is coming to an end, and the temperature difference between day and night is beginning to increase from today. In fact, the time of the beginning of autumn is different, and the impact on the weather behind is also very different. Knowing this knowledge can give us a better life for the rest of the day and lay the foundation for the right diet.

As the saying goes: early autumn, cold and stingy. Late autumn, hot cow, talking about the relationship between the beginning of autumn and the hot and cold weather.

The beginning of autumn is the standard for dividing the seasons according to the average temperature of the climate, and the average temperature must be below 22 for 5 consecutive days to be considered autumn, according to such a standard, the Jianghuai region generally enters autumn in mid to late September.

After the beginning of autumn, although the heat is difficult to get rid of for a while, although there is the aftermath of the "autumn tiger", the general trend is that the weather is gradually cooler. The diurnal difference in temperature is gradually noticeable, often during the day it is hot and the night is cooler. In addition, the meaning of autumn also means that the crops are about to ripen.

The beginning of autumn not only indicates that the hot summer is about to pass, but also that autumn is coming. It also means that the plants and trees are beginning to bear fruit and the harvest season has arrived. Therefore, in the beginning of autumn, there is a custom of sacrificing to the god of the land and celebrating the harvest.

There is a proverb in Beijing: "The early autumn is cool, and the late autumn is hot and the cow dies." What does this mean?

According to experts, there are two ways to determine whether the early or late beginning of autumn:

One is: to judge by the lunar calendar date on the day of the beginning of autumn. There is no big difference in the Gregorian calendar time of the beginning of autumn every year, but there is a difference in the lunar time. Generally speaking, the beginning of autumn is early in the sixth month of the lunar calendar and late in July.

The other is that if the time of the beginning of autumn is in the morning of that year, it is considered "early", and if the time of the beginning of autumn is in the afternoon or evening, it is considered "late".

If it rains in the beginning of autumn, autumn will come smoothly, but if it doesn't, there will be less rain in autumn, and the possibility of hot weather will increase.

The ancients began the morning with the sunrise at the time of Mao (5 o'clock to 7 o'clock) and the beginning of the evening with the palm lamp at the unitary time (5 o'clock to 19 o'clock).

There is actually such a saying about the early beginning of autumn and late autumn, if it is early autumn, then the weather will become cooler, not so hot, and even if it is in the middle of the day, you will also feel that the weather is slowly cooling.

And if it is late in autumn, the weather will continue to be high temperature for a period of time, not that after entering the autumn, the weather will instantly feel the change, continue to continue the high temperature weather, and wait until the end of the day, there will be changes, based on this, there is a "early autumn, cold and fluttering, late autumn, hot dead cow" sentence.

Some people say that it is distinguished according to the date of the lunar calendar, for example, some years are the beginning of autumn in June, and some are the beginning of autumn in July (all of them are lunar calendars), everyone thinks that the beginning of autumn in June is the early beginning of autumn, and the beginning of autumn in July is considered to be the late beginning of autumn.

Another theory is to calculate according to the time of the day of the beginning of autumn, if it is the beginning of autumn before 12 noon, it is early autumn, and if it is after 12 noon, it is late autumn.

You can distinguish whether it is an early or late beginning of autumn by the lunar time of the beginning of autumn.

On the solar calendar, the time of the beginning of autumn is relatively fixed, which is on August 7 or 8 every year, but it may be much worse on the lunar calendar. Taking the lunar month of July as a reference, if the beginning of autumn has not yet entered the lunar July, then it is called the early beginning of autumn; On the contrary, if it has entered the seventh month of the lunar calendar, it is called the late beginning of autumn.

As the name suggests, "Liqiu" means "the beginning of autumn in a year", and it is the 13th of the 24 solar terms in the lunar calendar. Normally, the beginning of autumn falls on August 7 or 8 every year. But it's not that the weather will be cool immediately in the "beginning of autumn", but that at this time of year, the weather is getting cooler, and the temperature difference between day and night begins to increase, even if it is hot during the day, there will be a burst of coolness at night.

In fact, after the beginning of autumn, there is also a saying that "after autumn, the old cow dies of heat". Because the beginning of autumn every year is within the dog days, only the hottest dog days of the year are completely over, and the weather will officially cool down. As the saying goes, "the early autumn is cool, and the late autumn is hot and the cow dies", which means that the morning and evening of the beginning of autumn have a great impact on the weather.

Old rural sayings: early autumn, cold; Late autumn, hot, this year's autumn is early or late.

There are two estimation methods for early and late early and late early autumn, one is calculated according to the beginning of autumn time, and the other is calculated according to the beginning of autumn month. When it is calculated according to the beginning of autumn in the morning and evening, it is usually said that the beginning of autumn during the day and the beginning of autumn at night is the early beginning of autumn, and the beginning of autumn at night is the late beginning of autumn.

Since the beginning of autumn is mostly between June or July of the lunar calendar, according to the beginning of autumn months, the beginning of autumn is the early beginning of autumn in June, and the late beginning of autumn in July. The beginning of autumn in 2021 is 14:53 on August 7 of the Gregorian calendar, the 29th day of the sixth month of the lunar calendar, so whether it is from the beginning of autumn time or the beginning of autumn month, this year is an early beginning of autumn.

As the saying goes, "the early autumn is cool, and the late autumn is hot and the cow dies", this saying means that if the early autumn is early, the weather will soon become cooler, and if the late autumn is late, the weather will be hot for a while, and the degree of heat can heat the old cow. For people, it is more comfortable for the weather to cool down earlier, but it is not good for the crops in the field.

Because after the beginning of autumn, there are many crops that are still in the growth stage, such as the middle rice is still in the filling moment, and the late rice has just been transplanted not long ago, which is the time when the sun is needed. If it is late in autumn, the higher temperatures are excellent for the crops, and there will be a good harvest in the following harvest season.

It is distinguished by the lunar time of the beginning of autumn.

Autumn is one of the four seasons of "Spring, Summer, Autumn and Winter". According to modern meteorology, the autumn in the north temperate zone is on August 23 (summer heat) and November 20 (light snow); Autumn in the southern temperate zone falls on February 19 (Northern Hemisphere rain) and May 21 (Northern Hemisphere Lesser Man).

In China, it is traditional to take the "beginning of autumn" of the 24 solar terms as the starting point of autumn and the end of the beginning of winter.

Autumn means that rainfall, storms, etc. tend to decline or decrease, and everything in nature begins to grow from lush to mature. The climate in autumn is divided into two phases, the early autumn is "muggy", and the mid-autumn tends to be "dry" and "cool".

Generally speaking, in autumn, the altitude angle of the sun gradually decreases, and the temperature gradually decreases from heat. The autumn breeze is cool, the scorching heat is gone, the fruit is full of branches, and the fields are golden.

Looking at the specific time of the beginning of autumn on the perpetual calendar, early refers to the time period of 0 o'clock to 12 o'clock, and late refers to the time period of 12 o'clock to 24 o'clock.

It has the specific time of the beginning of autumn each year.

I think the early or late days of the beginning of autumn are based on the interval between the time of "ambush" and the "beginning of autumn", the beginning of autumn within 20 days after the ambush is the early beginning of autumn, and the late beginning of autumn is outside 20 days after the ambush. In fact, it depends on how many days there are in the second volt, ten days in the second dog year is the early beginning of autumn, and twenty days in the second dog day is the late beginning of autumn! I thought ......

The proverbial "early" and "late" refer to the date of the lunar calendar, not the exact time to reach the angle of the ecliptic longitude。For example, the first day of June is early, and the first day of July is late. "Cold" and "hot" also refer to comparisons between the same lunar dates in different years.

If autumn begins on the first day of June, it is already the beginning of September on the first day of July on the solar calendar, so it is "cold"; And it is also the first day of July, if it is only the beginning of autumn, it is the beginning of August of the solar calendar, of course, "hot cow". A proverb that has been handed down for thousands of years should not be lightly said that "there is no scientific truth".

Climatic characteristics of early autumn.

From the point of view of climatic characteristics, in the beginning of autumn, due to the residual heat of midsummer, the autumn sun is raging, especially before and after the beginning of autumn, many areas are still in the heat, therefore, the folk have the saying of "autumn tiger". Meteorological data show that this hot weather often lasts until mid to late September, when the weather can really get cooler.

Meteorological experts reminded that "after the autumn, the heat kills", after the beginning of autumn, the temperature in most parts of our country is still very high, especially in some parts of southern China, the weather is still very hot, the heat is difficult to eliminate, the public should pay close attention to the weather forecast, beware of the "autumn tiger", be careful of heat stroke.

The above content refers to the encyclopedia early autumn.

The weather is cool in the morning in the beginning of autumn, and the weather is even hotter in the afternoon in the beginning of autumn.

The folk have "early autumn cool and fluttering."

Late autumn heat dead cow", said to be a genus.

If the beginning of autumn is in the morning, the weather is cool; If the beginning of autumn is after the afternoon, the weather will be even hotter. Whether it is early or late is to see what time is this specific time point, early refers to the time period of 0 o'clock to 12 o'clock, and late refers to the time period of 12 o'clock to 24 o'clock.

In China, the beginning of autumn is the beginning of autumn, which generally indicates that the hot summer is about to pass and autumn is coming. After the beginning of autumn, although the heat is difficult to get rid of for a while, and there is still the aftermath of the "autumn tiger", the general trend is that the weather is gradually cooler.
