How to tell the difference between spring, summer and autumn What is spring, summer, autumn and wint

The first classification method: China's traditional method of dividing the four seasons is to take the four of the 24 solar terms as the starting point of the four seasons, and the equinox and the two solstices as the midpoint. For example, the beginning of spring is the starting point, the ecliptic longitude of the sun is 315°, the spring equinox is the midpoint, the beginning of summer is the end point, the ecliptic longitude of the sun becomes 45°, and the sun runs 90° on the ecliptic.

This is a traditional, common method

The second classification: the astronomical classification (i.e., the Western classification) The division of the four seasons emphasizes the climatic significance of the four seasons, and takes the equinoxes and solstices as the starting point of the four seasons, such as the spring equinox in spring and the summer solstice as the ending point. These four seasons are one and a half months later than the four seasons traditionally divided in our country.

The third classification method: in order to accurately reflect the actual climatic conditions of various places, the four seasons are often divided into four seasons, that is, the modern scholar Zhang Baokun's classification method, which uses the average temperature to divide the four seasons. And stipulates:

The period when the average temperature is greater than or equal to 22 is summer, the period less than or equal to 10 is winter, and the period between 10 and 22 is spring or autumn. According to this criterion, the seasons in the mid-latitudes are consistent with the climate, and the temperature changes in spring, summer, autumn and winter in the low-latitudes and near the poles are very insignificant. At the same time, in the mid-latitudes, the length of each season is also different.

These are the four seasons of the climate. For example, Beijing has 55 days in spring, 103 days in summer, 50 days in autumn and 157 days in winter. This method can be combined with the specific climate and agriculture of various places, so it is used more

The fourth classification method: climate statistics, because January is generally the coldest month, therefore, spring, March, April, May Summer, June, July, August Autumn, September, October, November Winter, December, January, February This classification of the four seasons is more suitable for temperate regions with four distinct seasons.

If it is common sense to divide according to the plant, the leaves sprout in spring and are tender green. In summer, the foliage is lush. Autumn begins to lose its leaves and turn yellow.

I'm looking at the instant noodle seasoning package、、For example, it is solid now、、It means that winter is coming。

Dates: January, February, March Spring, April, May, June Summer, June, July, August Autumn.

It's spring, summer, autumn, winter.

1. Spring:"Stupid" means that everything begins to grow at this season.

2. Xia:False" means that all things begin to grow rapidly during this season.

3. Autumn:"just" means that all things are ripe when this season comes.

4. Winter:The meaning of "end" refers to the end of all things in this season.

Four Seasons: Four seasons refer to the four seasons that alternate in a year, namely spring, summer, autumn, and winter, with three months each. The four seasons of the year are formed because the earth revolves around the sun.

Due to the existence of the yellow-red angle, the annual change of the direct point of the sun moving back and forth between the north and south latitudes of the earth is 23°26, which causes the seasonal change of the height of the sun at noon and the seasonal change of the length of day and night, resulting in the seasonal change of the amount of solar energy obtained in various places, so that the change of the four seasons is formed.

Answer: How to divide the seasons:

One. It is the solar term method.

Astronomy, the spring equinox, summer solstice, autumn equinox, and winter solstice are the beginning of the four seasons. In ancient China, the beginning of spring, summer, autumn and winter were the beginning of the four seasons. This is all based on the position of the Earth in orbit.

Two. It's the lunar calendar.

Spring is from January to March, summer from April to June, autumn from July to September, and winter from October to December.

Three. It's the Gregorian calendar.

In meteorology, the solar calendar usually refers to spring from March to May, summer from June to August, autumn from September to November, and winter from December to February of the following year.

Four. It's phenology.

The willows are spreading their leaves, the peach blossoms are blooming, and spring is coming; The trees are shady, the red sun is scorching, and summer has arrived; The leaves of the fruit trees fall, the water is clear and the dew is cold, and the time sequence is autumn; The grass and flowers are withering, the north wind is howling, and the years are in winter.

The scientific division method is to quantify the fourth method, which is to use the average temperature of 5 days as an indicator to divide the four seasons: the average temperature is stable below 10, which is called winter, stable above 22, called summer, and stable between 10 and 22, that is, spring or autumn.

In winter, in summer, they live in the soil, where there are wheat and rape seeds, and after a while, wheat and rape poke out their little heads.

In winter, in summer, it lies in the granary, accompanied by corn, millet, peanuts and sorghum, as well as the joy of the farmer's uncle's harvest.

In winter, in summer, he lived in a cave, and he slept soundly with bears and snakes, and no one wanted to disturb anyone.

Poetry: 1. Poetry refers to the traditional poetry of the Han nationality in China, represented by ancient style poems, near-style poems and grammatical words. It is also one of the characteristics of the Chinese character cultural circle. It is generally believed that poetry is more suitable for "words", while words are more suitable for "lyricism".

2. Poetry is a literary art that expounds the soul, and poets and lyricists need to master mature artistic skills, and in accordance with strict rhythmic requirements, use concise language, dense rules, abundant emotions and rich imagery to express social life and the human spiritual world in a highly concentrated manner.

3. Chinese poetry originated in the pre-Qin period and flourished in the Tang Dynasty. Chinese words originated in the Sui and Tang dynasties and became popular in the Song dynasty. Chinese poetry originated from the folk and is actually a kind of grassroots literature. In 21st-century China, poetry is still popular among the general public.

The division of spring, summer, autumn and winter is divided according to the 24 solar terms.

Spring, from the beginning of spring to the beginning of summer, also called summer, is the first season of the year. During the period, it includes six solar terms, such as the beginning of spring, rain, sting, vernal equinox, Qingming, and valley rain.

Summer, from the beginning of summer to the beginning of autumn, is also called summer, the second season of the year. During the period, there are six solar terms, including the beginning of summer, Xiaoman, mangzhong, summer solstice, small summer, and great heat.

Autumn, from the beginning of autumn to the beginning of winter, also called autumn, is the third season of the year. During the period, it includes six solar terms, including the beginning of autumn, the summer heat, white dew, autumn equinox, cold dew, and frost.

Winter, from the beginning of winter to the beginning of spring, also called winter, is the fourth season of the year. During the period, there are six solar terms, including the beginning of winter, light snow, heavy snow, winter solstice, small cold, and big cold.

In different regions of our country, because of the differences in latitude and terrain, the length of spring, summer, autumn and winter is not consistent. The timing of entering a certain season is also inconsistent.
