Questions about the 24 solar terms and the four seasons

The folk name of our country is based on the position of the earth in the orbit and combined with the weather and natural landscape at that time.

The order is: the beginning of spring, rain, stunning, vernal equinox, Qingming, Guyu, Lixia, Xiaoman, mangzhong, summer solstice, small heat, great heat, beginning of autumn, summer heat, white dew, autumn equinox, cold dew, frost, beginning of winter, light snow, heavy snow, winter solstice, small cold, big cold.

Among them, the beginning of spring, the spring equinox, the beginning of summer, the summer solstice, the beginning of autumn, the autumn equinox, the beginning of winter, and the winter solstice, these festivals are used to divide the four seasons of the year, and "Sili" indicates the beginning of the season; "Two equinoxes" and "two solstices" are the turning points of the change of seasons, and the small heat, the big heat, the summer heat, the small cold, and the big cold indicate the hottest and coldest period of the year; White dew, cold dew and frost reflect the process and degree of temperature drop. Rain, valley rain, light rain, and heavy snow reflect the degree of rainfall and snowfall; Shocking, Qingming, Xiaoman, and miscanthus reflect the season and the growth trend of crops.

Twenty-four solar terms song: spring rain shocks the spring clear valley sky, summer is full of mangs and summer heat is connected, autumn dew and autumn frost fall, winter snow and snow winter small big cold.

Lichun: Lichun means the beginning, and Lichun is the beginning of spring.

Rain: Rainfall begins and gradually increases.

Sting: Stinging means to hide. Stinging refers to the sudden movement of spring thunder, which wakes up animals that are hibernating in the soil.

Vernal equinox: Equinox means equinox. The vernal equinox indicates the equinox of day and night.

Qingming: The weather is sunny and the vegetation is luxuriant.

Gu Yu: Rain gives birth to a hundred grains. Rainfall is abundant and timely, and cereal crops can thrive.

Beginning of summer: The beginning of summer.

Xiaoman: The grains of summer crops such as wheat are beginning to plump.

Miscanthus seeds: Wheat and other miscanthus crops are ripe.

Summer solstice: The hot summer is coming.

Xiaoxia: 夏 means hot. A small summer is when the climate starts to get hot.

Daido: The hottest time of the year.

Cold dew: The dew is cold and will freeze.

Frost falls: The weather is getting colder and frost is starting to appear.

Beginning of winter: The beginning of winter.

Light snow: It starts to snow.

Heavy snowfall: Snowfall increases and the ground may be covered with snow.

Winter solstice: The cold winter is coming.

Xiaohan: The climate is starting to get cold.

Big Chill: The coldest time of the year.

fromTwenty-four solar termsIt can be seen that the division of solar terms fully considers the changes in natural phenomena such as seasons, climate, and phenology. Among them, the beginning of springLixia, the beginning of autumn, the beginning of winter, the spring equinox, the autumn equinox, the summer solstice, and the winter solstice are used to reflect the seasons, dividing the year into four seasons: spring, summer, autumn, and winter. The spring equinox, autumn equinox, summer solstice, and winter solstice are divided from an astronomical point of view, reflectingSun altitudeA turning point for change.

Xiao XiaThe five solar terms, such as the Great Heat, the Great Heat, the Heat, the Small Cold, and the Great Cold, reflect the changes in temperature and are used to indicate the degree of cold and heat at different times of the year. Rain, valley rainLight snowThe four solar terms of heavy snow reflect the phenomenon of precipitation, indicating the time and intensity of rainfall and snowfall; White dewOn the surface, the three solar terms of cold dew and frost reflect the phenomenon of water vapor condensation and condensation, but in essence, they reflect the process and degree of gradual decline in temperature: when the temperature drops to a certain extent, water vapor appears condensation; The temperature continues to drop, not only with more condensation, but also cooler; When the temperature drops below zero degrees Celsius, the water vapor condenses into frost. The beginning of spring, the beginning of summer, the beginning of autumn, and the beginning of winter reflect the beginning of the four seasons.

Due to the vast territory of China, with a very obvious monsoon and continental climate, the weather and climate vary greatly from place to place, so the seasonal changes in different regions are also very different.

Xiaoman. Miscanthus seeds reflect the maturity and harvest of the crops concerned; The sting and Qingming reflect the natural phenological phenomenon, especially the sting, which uses the first thunder in the sky and the revival of the underground stinging insects to herald the return of spring.

The 24 solar terms are a knowledge system formed by observing the annual movement of the sun and recognizing the changes in season, climate, and phenology in a year. It divides the annual trajectory of the sun into 24 equal parts, each equal part is a solar term, which begins at the beginning of spring and ends with the great cold, and the cycle repeats, and the 24 solar terms are divided into seasons of spring, summer, autumn and winter.

The 24 solar terms are the result of the long-term observation, exploration and summary of astronomy, meteorology and phenology by China's laborers, and are the unique great scientific and technological achievements of China's working people. For the sake of memorization, people have compiled it into a solar term song.

Some people also wrote poems in seven words.

The 24 solar terms form the four seasons according to the change of temperature, and the four seasons are generally divided according to the 24 solar terms, the season with the temperature from low to high is called spring, the season with the highest temperature is called summer, the season with the temperature from high to low is called autumn, the season with the lowest temperature is called winter, and the beginning of spring, the beginning of summer, the beginning of autumn, and the beginning of winter also reflect the beginning of the four seasons.

There is a certain relationship between the 24 solar terms and the seasons, the 24 solar terms consider the changes in natural phenomena such as seasonal climate phenology, the four seasons are divided according to the 24 solar terms, the beginning of spring, the beginning of summer, the beginning of autumn, and the beginning of winter also reflect the beginning of the four seasons, and each season has 6 solar terms.

What are the 24 solar terms related to.

What is the 24 solar terms related to, there are 24 solar terms in a year, many people do not know about the 24 solar terms, and there are many factors that affect the solar terms. Let me introduce you to the relevant information about what the 24 solar terms are related to, let's take a look.

It is a Chinese calendar related to the solar calendar, and the two solar terms are about 15 days apart. The 24 solar terms are a unique invention of the Chinese calendar and are divided according to the position of the sun on the ecliptic.

The Mid-Autumn Festival, for example, is associated with the autumnal equinox.

The autumn equinox is the sixteenth of the 24 solar terms, and the time is generally September 22 and 24 of the Gregorian calendar every year. On the day of the autumnal equinox, the sun reaches 180° of ecliptic longitude (the point of the autumnal equinox), which is almost direct to the Earth's equator, and the day and night are equal in length all over the world (not taking into account the refraction of sunlight by the atmosphere and the shadow of morning and dusk).

The autumn equinox used to be the traditional "moon festival". The current Mid-Autumn Festival is derived from the traditional "Moon Festival".

6 solar terms per season:

Spring rain shocks the spring clear valley day,6 solar terms in spring: the beginning of spring rain stings the spring equinox Qingming Valley rain.

Summer is full of mang, summer and summer are connected,6 solar terms in summer: the beginning of summer, the small mango planting, the summer solstice, the small summer heat, the big heat.

Autumn white autumn frost falls,Autumn 6 solar terms: the beginning of autumn, the summer white dew, the autumn equinox, the cold dew and frost.

Winter snow, snow, winter small and cold, 6 solar terms in winter: light snow in the beginning of winter, heavy snow in winter, small cold and big cold in winter.

The four seasons of the year are divided into four seasons because the Earth's orbit around the Sun is elliptical, so the distance from the Earth to the Sun is different, and it will be directly irradiated by different sunlight at different times, resulting in changes in temperature and climate. The 24 solar terms are a concept in the Chinese lunar culture, which is divided according to different signs such as the position of the sun at the equator, astronomical phenomena, and climate change. The division of the 24 solar terms is not only a record of climate change, but also a necessity for China's peasant farming life, which is conducive to the arrangement of agricultural activities by farmers, such as farming, harvesting, seed production, and seedling raising.

So as to ensure the smooth development of agricultural production and increase production. Therefore, the division and content of the 24 solar terms have deeply affected the life, culture and traditional customs of the Chinese.

In the process of the earth's rotation around the sun, according to the distance from the sun and the declination angle of the earth's rotation, the earth's surface is alternated between cold and hot north and south, resulting in the appearance of the four seasons on the earth's surface.

The 24 solar terms are a supplementary calendar established in ancient China to guide agricultural affairs, which refers to the 24 solar terms that combine the air calendar and the solar calendar. In order to adapt to the severe cold and heat, the industrious and intelligent Chinese ancestors created the 24 solar terms, so that people can understand the natural time sequence more efficiently and better arrange agricultural production.

In short, this is a set of methods for the ancients to summarize the climate based on their own feelings and changes in the surrounding environment, which is explained by modern science, which is the result of the distance of the earth from the sun at different times, as shown in the figure below

There are four seasons and 24 solar terms throughout the year, mainly due to the knots of the earth's revolving circle around the sun.

1.The Earth's orbit around the Sun is elliptical, so the distance from the Earth to the Sun is constantly changing. When the Earth is closest to the Sun, it is called perihelion, when the Sun shines directly on the Southern Hemisphere, and the Sun altitude angle is smaller in various parts of the Northern Hemisphere, the day time is shorter, and the night time is longer, that is, winter.

When the earth is farthest from the sun, it is called aphelion, when the sun shines directly on the northern hemisphere, the solar altitude angle in the northern hemisphere is larger, the day time is longer, the night time is shorter, and the sensitivity is summer. Thus, the change in the four seasons of the year is caused by the Earth's revolution around the Sun.

2.The 24 solar terms are a concept in the traditional Chinese calendar, divided according to the position of the sun on the ecliptic and different signs such as astronomical phenomena and climate change. Among them, the "solar terms" in the 24 solar terms refer to the seasons, festivals, and signs of climate change, and there is usually a solar term every fifteen days.

For example, the spring and autumn equinoxes are equinoxes of day and night, the summer solstice is the longest day in the Northern Hemisphere, and the winter solstice is the shortest day in the Northern Hemisphere.

In short, there are four seasons and 24 solar terms in a year, which is caused by the natural law caused by the earth's revolution around the sun. These laws not only reflect changes in climate and phenology, but also have a profound impact on Chinese culture and traditional customs.

Problem description: We can literally divide the 24 solar terms into three categories: the first category reflects the seasons from an astronomical point of view, such as "four stands", "two equinoxes", and "two solstices"; The second type reflects the seasons in terms of climatic conditions; The third category is to reflect the seasons in terms of phenological phenomena.

Accordingly, the following questions are asked:

1) Find out the solar terms that you think reflect the seasons in terms of climate conditions;

2) Find out which solar terms you think reflect the seasons in terms of phenological phenomena;

3) How do you think it can be classified correctly or by example?

Analysis: The first category is a reflection of the seasons. The equinoxes (spring equinox, autumn equinox), solstices (summer solstice, winter solstice), and four li (beginning of spring, beginning of summer, beginning of autumn, beginning of winter) are used to indicate the seasons, and the year is divided into four seasons.

The equinox, the solstice, is the turning point in the change of the height of the sun. Because it is divided from an astronomical point of view, it is applicable to all regions of our country. This is not the case with Sili.

Although it also reflects the beginning of the season from the astronomical perspective, due to the vast territory of our country, the monsoon and continental nature of the climate are extremely significant, and the climate is very different, so the start date and duration of the four seasons are not the same in some areas, and the four seasons are distinct in some areas, and some areas are not very obvious, and even a whole season does not appear. For example, the alpine regions north of Aihui in Heilongjiang Province and the Qinghai-Tibet Plateau do not have summer. On the Qinghai-Tibet Plateau, there is a saying:

The summer days in June are still cotton, and most of the year round is cold." There is no winter in the south of Fuzhou in South China, and some areas are in summer almost all year round, and it is really "the grass does not wither in winter, and the flowers bloom even in spring", "all four seasons are summer, and a rain becomes autumn". Yunnan-Guizhou and other plateaus are a scene again, the winter is short and there is no summer, Kunming has the name of "four seasons like spring".

Therefore, although Sili is astronomically divided, it has a strong regional character, and it cannot be adapted to the whole country.

The second category reflects the characteristics of the climate. There are five solar terms that directly reflect the heat situation: small heat, big heat, summer heat, small cold, and big cold, which are used to indicate the degree of cold and heat at different times of the year and the heat is about to pass. There are four solar terms that directly reflect the phenomenon of precipitation: rain, valley rain, light snow, and heavy snow, indicating the time and intensity of rainfall and snowfall.

In addition, although the three solar terms of white dew, cold dew, and frost fall are water vapor condensation and condensation, they also reflect the process of the gradual decline of the temperature of the temperature group and the degree of temperature drop in each solar term. First, the temperature began to decrease, and there was more water vapor condensation; Later, the temperature dropped even more, not only dew, but also cooled, but not yet frozen; Finally, the temperature drops below zero degrees Celsius, and the water vapor condenses into frost. From the perspective of agricultural production, the caloric significance of these three solar terms is greater than their water significance, which is specific and vivid.

The third category is the one that reflects phenological phenomena. Xiaoman and miscanthus reflect the maturity and harvest of the relevant crops; The sting and Qingming reflect the natural phenological phenomena, especially the sting, which uses the first thunder in the sky and the revival of the underground stinging insects to inform all things in heaven and earth of the information of spring returning to the earth.

Meaning: There are two solar terms in each month in the first half of the year, the first solar term is around the 6th, and the latter is around the 21st, with a difference of 1 2 days. There are two festivals in each month in the second half of the year, the first one is around the 8th, and the latter is around the 23rd, with a difference of 1 2 days.

The song of the 24 solar terms is a small poem compiled to facilitate the memory of the 24 solar terms in the ancient calendar of our country, and there are many versions that have been passed down to this day. The solar terms refer to the 24 seasons and climate, which is a calendar established in ancient China to represent the changes of the seasons and guide agricultural affairs, and is the crystallization of the long-term experience and wisdom of the working people in ancient China.

Because the Chinese lunar calendar is a kind of "luni-solar calendar", that is, according to the sun and according to the movement of the moon to formulate the gods, so can not fully reflect the solar cycle, but China is an agricultural society, agriculture needs to strictly understand the solar situation, agricultural work is completely based on the repentance of the sun, so in the calendar and added a separate reflection of the solar cycle of the "twenty-four solar terms", as a standard for determining the leap month.
