What is the meaning of the vernal equinox What does the vernal equinox mean and what does the vernal

Equinox Definition: From Chinese.

One of the 24 solar terms, on March 20 or 21. On this day, the day and night are the same in both the northern and southern hemispheres.

The vernal equinox is the fourth of the 24 solar terms and is an important time for farming. The sun shines directly on the Earth's equator, and day and night are almost equal. In ancient times, the beginning of spring to the beginning of summer was spring, and the spring equinox was in the middle of the three months of spring.

8] The sun reaches 0 degrees of ecliptic longitude and intersects on March 19 and 22 in the Gregorian calendar every year. "The vernal equinox, yin and yang are half and half. Therefore, the day and night are even, and the cold and heat are even".

It is recorded in the lunar book that "Douzhiren is the spring equinox, about the week, the day and night in the northern and southern hemispheres are evenly divided, and it is half of spring, so it is called the spring equinox." "From this day on, the direct position of the sun gradually shifts northward, and the length of day and night in the northern and southern hemispheres also changes, with the northern hemisphere having short days and short nights and the southern hemisphere doing the opposite. [1]

As soon as the vernal equinox arrives, the rain increases significantly, and the average ground temperature in China has stabilized at more than 10 degrees, which is the climatological definition of spring temperature. After the vernal equinox, the climate is mild, rainy, and sunny, and the wintering crops in most parts of China enter the spring growth stage, which is also the sowing period for early rice. [1]

There are three waits for the vernal equinox: "one waits for the Xuanniao to arrive, the second waits for the thunder to make a sound, and the third waits for the beginning of the electricity". Sending a spring ox is also one of the customs of the spring equinox. In addition, the spring equinox customs such as sacrificing birds and sticking the beaks of birds also carry people's expectations for the farming season.

The vernal equinox represents the meaning:

Day and night are almost equal.

As the saying goes: "When the spring equinox wheat rises, the fertilizer and water must follow". A spring rain and a warm one, after the spring rain busy plowing the fields.

The busy spring season is about to begin, and spring management, spring ploughing, and spring planting are about to enter a busy stage. After the spring equinox, overwintering crops enter the growth stage, and field management should be strengthened. Due to the rapid rise of temperature and relatively large water demand, farmers should strengthen water storage and moisture conservation.

In the areas with little rain in spring in the north, we should pay close attention to spring irrigation, water pulling, apply jointing fertilizer, and pay attention to preventing late frost damage; The south still needs to continue to do a good job in draining and preventing flooding and staining. The early rice seedling raising in the south of the Yangtze River and the early rice film seedling raising in the Jianghuai area have begun, and the cold and warm weather changes frequently in early spring, so it is necessary to pay attention to soaking and germinating when the cold air comes, and sowing at the end of the cold air. [2]

In the northern regions, where "spring rain is as expensive as oil," resisting spring drought is still an important agricultural activity during the spring equinox, and these localities should pay close attention to spring irrigation, do a good job of watering and watering, apply jointing fertilizer, and strengthen preparations for resisting spring drought and frost damage. [2]

In spring, when the weather warms up, there is often the invasion of cold air, especially in the south of the Yangtze River and along the Yangtze River, the cold air from the north meets the warm and humid airflow from the south, resulting in spring rain, which makes the temperature significantly lower, and it forms what people often call "inverted spring cold".

The vernal equinox is one of the 24 solar terms, when the sun is located at 0° of the ecliptic longitude (the vernal equinox). On the day of the vernal equinox, the sun shines directly on the Earth's equator, and the seasons in the northern and southern hemispheres are reversed, with the northern hemisphere being the vernal equinox and the southern hemisphere being the autumnal equinox.

At the vernal equinox, theoretically, the global day and night are of equal length. After the vernal equinox, the days get longer and the nights get shorter in the Northern Hemisphere, and the nights get longer and the days shorter in the Southern Hemisphere. At the vernal equinox, the sun's dimensions change, and the temperature rises throughout the day.

After the spring equinox, there is also more rain in many areas, which is commonly known as spring rain.

As we all know, there are 24 solar terms, including 12 months, and 15 days before and after each solar term. And the "five days" are called one wait, and the three waits are a solar term. In ancient China, the working people named the "three seasons" of each solar term according to the climatic characteristics and some special phenomena at that time, and used them to concisely express the weather and other characteristics at that time.

The vernal equinox is when the sun shines directly on the Earth's equator, the global day and night are equal, and the seasons in the northern and southern hemispheres are reversed, with spring in the northern hemisphere and autumn in the southern hemisphere.

Spring is coming with a clear seasonal distinction The vernal equinox, also known as the "middle of the day" and "day and night equinox" in ancient times, is on March 20 or 21 every year, when the sun reaches the ecliptic longitude of 0°. According to the "Seventy-two Candidate Explanations of the Lunar Order": "In the middle of February, half of the divider is also, and this should be half of the ninety days, so it is called the divide."

In addition, "Spring and Autumn Dew, Yin and Yang in and Out of the Upper and Lower Chapters" said: "For the spring equinox, yin and yang are half of each other, so the day and night are even, and the cold and summer are even." "So, equinox'Meaning, one refers to the time of the day day and night are equally divided, each of which is 12 hours; The second is that in ancient times, the beginning of spring to the beginning of summer was spring, and the spring equinox was in the three months of spring, and the spring was equally divided.

In ancient China, the spring equinox was divided into three phases: "one is the arrival of the Yuan bird; The second is to wait for Lei Nai to speak; Three waiting for the start of the call. That is, after the vernal equinox, the swallows will come from the south, and when it rains, the sky will thunder and lightning.

The vernal equinox is one of the 24 solar terms, in ancient times, it was also called "the middle of the day", "the equinox of day and night", "the month of mid-spring", around March 21 (20-22) of the Huai Bureau every year, the lunar calendar date is not fixed, when the sun reaches the vernal equinox 0 ° of the yellow longitude.

According to the "Seventy-two Candidate Explanations of the Lunar Order": "In the middle of February, half of the divider is also, and this should be half of the ninety days, so it is called the divide." Another "Spring and Autumn Dew, Yin and Yang Town in and Out of the Upper and Lower Chapters" said:

In the spring equinox, yin and yang are half of each other, so the day and night are even, and the cold and heat are flat. There is a "History of the Ming Dynasty: Calendar I" said: "The divider, the point where the yellow and red intersect, the sun travels here, it is the equivalence of day and night."

Therefore, the meaning of the vernal equinox is that the time of day and night are equally equinoxed, each of which is 12 hours; The second is that in ancient times, the beginning of spring to the beginning of summer was spring, and the spring equinox was in the three months of spring, and the spring was equally divided.

In ancient China, the vernal equinox was divided into three phases: "one is the arrival of the first bird; The second is to wait for Lei Nai to speak; The three lead cores let the first power be heard. That is, after the vernal equinox, the swallows will come from the south, and when it rains, the sky will thunder and lightning.

The vernal equinox is recorded in the ancient Chinese calendar as follows: "Three days before the vernal equinox, the sun enters the equator".

<> vernal equinox is one of the 24 solar terms and the fourth solar term of spring. The yellow longitude of the sun reaches 0°, and it is intersected on March 19-22 of the Gregorian calendar every year. The vernal equinox is of great astronomical significance, on the day of the vernal equinox, the day and night in the northern and southern hemispheres are as flat as the middle of the equinox, and since this day the position of the direct sun continues to move from the equator to the northern hemisphere, and the days in the northern hemisphere begin to be longer than the night, and the southern hemisphere is the opposite.

In terms of climate, there are also obvious special evidence, except for the Qinghai-Tibet Plateau, the northeast, the northwest and the northern part of North China, all of which have entered a bright spring.

The meaning of the vernal equinox is that the time of day is equal to the day and night, each of which is 12 hours; The second is that in ancient times, the beginning of spring to the beginning of summer was the spring slag, and the spring equinox was in the middle of the three months of spring, and the spring was equally divided. After the vernal equinox, the climate is mild, with abundant rain and sunny sunshine. During the spring equinox, Chinese folk have customs such as flying kites, eating spring vegetables, and standing eggs.

The vernal equinox also means equinoxical spring, so the vernal equinox was also called "the middle of the day" in ancient times""Day and night""Mid-Spring Moon". On the day of the vernal equinox, the sun shines directly on the Earth's equator, and day and night are almost equal. According to Yuan Wucheng's book "Seventy-two Candidate Explanations of the Lunar Order", it is explained:

In the middle of February, half of the divider is also, this should be half of the ninety days, so it is called the divide. "Another "Spring and Autumn Dew" said: "The spring equinox, yin and yang are half of each other, so the day and night are even, and the cold and heat are even."

Lunar book: "Dou Zhiren is the spring equinox, about the week, the north and south hemispheres are equal to day and night (except for the two poles), and when the spring is half, so it is called the spring equinox."

It is one of the 24 solar terms and the fourth solar term in spring. The yellow longitude of the sun reaches 0°, and it is intersected on March 19-22 of the Gregorian calendar every year.

The meaning of the vernal equinox is as follows:

The "points" of the vernal equinox have two meanings, one is the "equinoxical equinox", the tradition is between the beginning of spring and the beginning of the sale, and the day of the vernal equinox is in the middle of the two solar terms, which happens to divide the spring; Another meaning is "equinox", on the day of the vernal equinox, the sun shines directly on the equator, and the day and night are of equal length, each for 12 hours. The climate of the vernal equinox is characterized by warm and sunny weather. At this time, Chinese folk have customs such as flying kites, eating spring vegetables, and standing eggs.

Dou Zhi Mao, the yellow longitude of the sun reaches 0 °, and it is intersected on March 19-22 of the Gregorian calendar every year. The vernal equinox is of astronomical significance, on the day of the vernal equinox, the sun hits the equator, the northern and southern hemispheres equinox, and since this day, the position of the sun continues from the equatologist to the northern hemisphere, and the days begin to be longer than night in the northern hemisphere, and the southern hemisphere is the opposite.

In terms of climate, there are also obvious characteristics, after the vernal equinox, China has entered a bright spring except for the Qinghai-Tibet Plateau, Northeast China, Northwest China and the northern part of North China.

During the spring equinox, China enters a bright spring except for the Qinghai-Tibet Plateau, Northeast China, Northwest China and the northern part of Tinghong North China. Except for the alpine mountainous areas with winters all year round and areas north of 45°N, the average daily temperature in all parts of China has risen steadily above 0. At this time, the severe cold has passed, and the temperature has risen rapidly, especially in North China and the Huanghuai Plain, the daily average temperature has risen to more than 10 at the same time as the rainy Yangtze River and Jiangnan region, and entered the bright spring.
