Is the day longer or shorter after the summer solstice? What are the solar terms from summer to the future?

After summer, are the days longer or shorter? Solstice: It's getting shorter and shorter.

On the solstice in summer, the day is the longest and the night is the shortest. After the summer solstice, the days begin to get shorter and the nights begin to get longer. On the day of the autumnal equinox, day and night are the same, and then the night continues to get longer, reaching the longest winter solstice. After the winter solstice, the night begins to shorten and the vernal equinox reaches the same length as day and night;

The nights continue to get shorter until the summer solstice, reaching the shortest night, and so on.

Under normal circumstances, as long as the summer solstice ends, the sun will turn to the south day by day. However, since the earth will reach the apohelion on the 12th or 13th day from summer to the future, even the short-term daytime speed from summer to the future is very slow and almost imperceptible, but after the apohelion, the speed of the earth's rotation will gradually accelerate, and people will feel that the daytime is obviously shortened.

On the contrary, there is a folk saying that "the days will get longer as soon as the winter is over." This is because the earth reaches perihelion in about 12 or 13 days from winter to the future, so the speed of the earth's rotation increases during the winter to the sun, so the speed of a day is obvious.

English Translation of Summer Solstice: Summer Solstice

On the summer solstice, Beidou points to B. The meridian of the sun is 90 degrees. When the sun is at the "Summer Solstice Point" at 90 degrees of the yellow meridian, it is almost directly above the Tropic of Cancer, and the sun is the highest in the northern hemisphere at noon. This day is the longest day and the shortest night in the northern hemisphere. From this day on, it entered the hot season, when everything in the world grew most vigorously. In ancient times, the heart also called this day the northern solstice, meaning the northernmost day when the sun was born.

Brief introduction of summer solstice

On the solstice of summer, the sun shines directly on the Tropic of Cancer, which is the longest day of the year in the northern hemisphere. It takes about fourteen hours from sunrise to sunset in all parts of Sichuan. Although the summer solstice has the longest day and the highest sun height, it is not the hottest time of the year. Because the heat in the near-surface layer is still accumulating at this time, and it has not reached its maximum. After the summer solstice, due to the vigorous growth of crops, the rapid growth and spread of weeds, pests and diseases, and the golden season of grass, fertilizer and livestock flourishing in plateau pastoral areas, agricultural production in our province has entered the field management period. At this time, the rainfall in the western part of the basin increased obviously, which gradually changed the distribution trend of rainfall in the basin from the east to the east since the spring. If there is a summer drought, it is generally expected to be lifted at this time. In recent 30 years, the number of large-scale floods in the western part of the basin in late June is small, but the degree is serious. Therefore, special attention should be paid to preparing for flood control. The solar term from summer solstice is the solar term with the largest annual rainfall in the eastern part of the basin, which is often controlled by subtropical high in the future, resulting in summer drought. In order to enhance drought resistance and win a bumper harvest in agriculture, it is an important measure to capture and store pre-dormant rainwater in these areas. After the summer solstice, the ground is heated strongly and the air convection is strong, and thunderstorms are often easy to form in the afternoon to evening. This kind of hot thunderstorm comes and goes, and the rainfall range is small. People call it "dividing fields in summer and rain". In Sichuan, Liu Yuxi, a poet of the Tang Dynasty, skillfully used this weather to write a famous poem "Rising in the east and descending in the west, the road is sunny and sunny".

What are the solar terms from summer to the future? It's a little hot in summer.

Summer is 1 1 of the 24 solar terms. On July 7th or 8th every year, when the sun reaches 105, it is a slight summer heat. Summer heat, which means hot, is a little hot, not very hot. It's getting hotter, but not the hottest.

In ancient China, the summer heat was divided into three periods: "First, it was warm and windy; Second, wait for crickets to live in space; The third waiting eagle began to crow. "

When the warm wind arrives, it means that after the light summer, there is no cool wind on the earth, and all the winds are carrying heat waves.

Second, waiting for crickets to live in space, which is called "cricket" by northern customs. A class of harmful insects with dark brown body and aggressive males, whose wings can make sounds when rubbed. The frequency of crickets' sounds depends on the number of times they hit their teeth per second, ranging from 65,438+0,500 cycles per second for the largest cricket species to nearly 65,438+00,000 cycles per second for the smallest cricket species. The rate of singing is directly related to the temperature, and increases with the increase of temperature. The most common song is the courtship that attracts females; There are courtship sounds that induce females to mate, and there are also fighting sounds that drive away other males.

Ju Yu, the second waiting cricket, pointed out that five days later, due to the heat, the cricket left the field and went to the corner of the yard for the summer.

The three-waiting eagle is a kind of raptor. Eagle is a typical representative of eagle-shaped birds of prey. There are three most common species in China: goshawk, sparrow hawk and sparrow hawk. The word eagle in a broad sense is also often used to refer to other birds of the family Eagle (such as kites, owls, harriers), and even to some birds of the family Eagle (such as falcon and Karakala eagle). It is also the suffix of some non-eagle birds' names (because there are many analogies in Chinese names).

Three waiting eagles begin to gather, which means that in five days, eagles will move in the cool high air because the ground temperature is too high.
