The summer solar term of 20 14 is August 23rd of 20 14 and Saturday of July 28th of the lunar calendar. What does it mean to spend the summer in solar terms?
What does it mean to spend the summer in solar terms?
"Chu" means to hide and die, and "early summer" means that the hot summer has passed. "Twenty-four solar terms" said: "Go, go, the heat is over." "Chu" means termination, which means that the summer heat is about to pass, the summer heat will end on this day, and the temperature in most parts of China will gradually drop. Being in summer is not only different from mild summer heat and severe summer heat, but also different from mild cold and severe cold solar terms. This is a solar term representing the transition from hot to cold.
In ancient China, the summer heat was divided into three stages: "The eagle is a sacrificial bird; Second, wait for the beginning of heaven and earth; Three Hou Wonaideng. " In this solar term, eagles began to prey on birds in large numbers; Everything between heaven and earth began to wither; The word "He" in "He Naideng" refers to millet, millet, rice and sorghum crops, and "Deng" means maturity.
After the summer, the direct point of the sun continued to move southward, the solar radiation weakened, and the subtropical high retreated southward by leaps and bounds. At this time, the temperature began to drop, and the summer heat was no longer threatening. There are proverbs that "an autumn rain and a cold", "beginning of autumn is cool in summer" and "it's raining in summer" are direct descriptions of the climate change in the hot summer season.
Although the subtropical high, which is dominant in summer, strides southward, it will never give up its advantage easily and easily retreat into the sea of the western Pacific. In the southern areas under its control, people who have just enjoyed a little autumn coolness often feel the hot weather at the end of summer, which is a veritable "autumn tiger". Therefore, there is a saying that "big summer heat and small summer heat are not summer heat, and beginning of autumn summer heat is just summer heat".
It is often after the autumn tiger weather is over that the crisp autumn weather will be ushered in. Chengdu is usually in the middle and late September. Generally speaking, during the high temperature in summer, the climate is characterized by hot days, cool in the morning and evening, and the temperature difference between day and night gradually increases. Meteorologists said that in West China and Southwest China, including Sichuan, there was another major weather feature in September-autumn rain in West China. At this time, most parts of China began to enter the period of less rain, while there were more autumn rains in West China, which is a unique weather phenomenon in autumn in West China.
The main rainfall periods appear in September and 10, which is characterized by rainy days and rain in Mao Mao, so the rainfall is not large. In addition, although the thunderstorm activity at this time is not as active as in summer, there are still many thunderstorms in the southwest and west due to the edge of subtropical high and the role of mountains.
What does it mean to spend the summer in 24 solar terms? First understand the basic knowledge of two solar terms, that is, spending the summer and the Millennium.
Summer and Millennium are both one of the 24 solar terms, and autumn is also two solar terms, but each has its own characteristics.
Summer: It is the second solar term in autumn. Generally, it passes around August 23rd every year, and the solar calendar reaches 150, which means five. "Out" usually means to stop, leave or come out, that is, it has left the hot weather, commonly known as the summer heat. It has three stages: the eagle worships birds, the heavens and the earth begin to sink, and the lotus grows, that is to say, the weather is bleak, the grain is abundant, and the eagle catches birds, which is the main feature of summer heat.
Millennium: It is the third solar term in autumn, usually on September 7-9 in Gregorian calendar, when the sun reaches 165 degrees. "White": The dew on the grass in the morning is crystal clear and the color is clear. In addition, autumn belongs to gold and white is gold, so it is called Bailu. There are three classes: geese come, birds return, and birds are ashamed. In other words, Hongyan and Swallows migrated to the south, and resident birds began to store food for the winter.
Second, reanalyze the meaning of "it doesn't rain in summer, and it's dry to the bottom".
Knowing the meaning of the two solar terms, let's analyze this proverb again.
The proverb: "It doesn't rain in summer, until the ass is bare", the meaning is very clear! If it doesn't rain in summer, the drought will last until the bottom of the Millennium solar terms, that is, before the autumn equinox solar terms, which also indicates that there will be dry, rainy and hot weather in autumn. Is that so? Let's look at what other proverbs say.
There is also an agricultural proverb that says, "See the sun in summer and kill fish in the river". It seems that the drought is a bit serious. If in summer and solar terms, the sun is shining, the sky is clear, and Wan Li appears, it means that there is a lack of rain in autumn, the weather is dry, and even the river dries up, and fish are also facing death.
It doesn't rain in summer, and the experience accumulated by our ancestors is drought and little rain. When will it end? Let's analyze the agricultural proverbs and see how long it will take.
When will the autumn drought end?
Then how to determine the drought time? Actually, it's very simple! It can not only calculate the probability, but also find the probability accurately. Let's do a simple calculation today.
Probability calculation: Usually, each solar term is about 15 days, and from long summer to the end of the Millennium, that is, before the autumnal equinox, it just spans two solar terms, about 30 days, that is, about one month. It can be seen that the drought time is longer. Is this good for crop growth? It can be said that there are advantages and disadvantages. Let's see what the agricultural proverb says!
The proverb says, "When it rains in early autumn, everything harvests; It rains in early summer and everything withers "; Others said, "Every grain in the summer rain is rice." . Is this a contradiction? Actually, it is not! This is aimed at different regions and different crops, so the results are different, on the contrary. Rumor 1 accords with corn, sorghum, soybean and millet in the north. When mature, you need plenty of sunshine and put it in storage in time. Myth 2: For late rice in the south, it needs enough water to participate in healthy growth.
What does it mean to spend the summer in 24 solar terms? How long will it be hot after the summer of 2022?
Depending on the place, it will still be hot in logarithmic areas 18 days or so. It is very cold in summer, which means it is still very hot at noon. It's not autumn in beginning of autumn. After the Millennium cools down, the summer heat must be at the beginning of the autumn Millennium, with summer heat and autumn cool. The temperature difference between day and night is large, so it is necessary to prevent colds and discomfort, and it is cool in summer and autumn, with obvious seasonal changes, which is not suitable, especially for Xian Yi, young and old. Because of weak resistance and immunity, it is easy to get sick due to seasonal changes, and the temperature is hot and cold, dry and wet.
Why is it still so hot in summer?
It has something to do with the region.
By the end of the summer solar term, the summer heat is often still there, continuing the autumn tiger weather of "cool in the morning and evening, hot at noon" since autumn. In addition, autumn tigers generally appear from early August to mid-September, and the duration of the whole year is long and short, and they often last for a period of time before and after the summer solar term in late August!
In addition, China has a vast territory, and the autumn tigers in the south often delay the arrival of two or three solar terms than those in the north of the Yangtze River, that is, when the beginning of autumn in the north appears, maybe the south will have to wait until the Millennium and the autumnal equinox!
Is summer the hottest day?
number
Although it has the word summer fever, it is not the hottest time of the year. Summer is a solar term reflecting the temperature change. "Chu" means to hide and die, and "early summer" means that the hot summer has passed. As the height of the sun decreases, the heat it brings will also decrease. The heat has gradually subsided. Although the summer heat is decreasing and the temperature will not suddenly rise, there will still be short-term reheat weather during this period, but it is not really cool. It usually gets cold after a thousand years.
