Question 1: What does the summer solstice mean? Summer solstice is one of the 24 solar terms, which occurs on June 2 1 or 22 of the Gregorian calendar every year. On the day of the summer solstice, the sun moves to 90 degrees of the yellow meridian (in Gemini), and the position of the sun directly on the ground reaches the northernmost point of the year, almost directly on the tropic of cancer. At this time, the sunshine time is the longest in the northern hemisphere. In Beijing, the daytime can be as long as 15 hours. On this day, the northern hemisphere gets the most sunshine, almost twice as much as the southern hemisphere.

During the Millennium, ancestors used earth gauges to measure the shadow of the sun, thus determining the summer. The annual summer solstice begins on June 2nd1day (or 22nd) and ends on July 7th (or 8th). According to "Zunxian Manuscript", "The sun arrives in the north, the days are long and the shadows are short, so it is called the summer solstice. At best, it is excellent. " On the day of summer solstice, the sun directly reaches the northernmost part of the year, almost directly to the Tropic of Cancer (23 26' north latitude), and the daytime in the northern hemisphere reaches the longest, and the farther north it is, the longer it is. For example, the daily length of Haikou in Hainan is a little more than 13 hours, Hangzhou is 14 hours, Beijing is about 15 hours, and Mohe in Heilongjiang can reach 17 hours. From summer to the future, the position of direct sunlight on the ground gradually moves southward, and the daytime in the northern hemisphere is shortened day by day.

Question 3: When is the summer solstice? What does summer solstice mean? Every June 2 1 or so. The direct point of the sun is on the tropic of cancer, with the longest day and the shortest night in all parts of the northern hemisphere. The higher the latitude in the northern hemisphere, the longer the day and the shorter the night, and the arctic circle appears extremely daytime. The higher the latitude in the southern hemisphere, the longer the night and the shorter the day, and the polar night phenomenon appears in the Antarctic circle. The farther away from the tropic of cancer on the earth, the more inclined the sun's rays are, and the less solar heat is obtained. In contrast, the northern hemisphere gets more heat than the southern hemisphere at this time. Generally speaking, June, July and August are summer in the northern hemisphere and winter in the southern hemisphere.

On the day of the summer solstice, except for the polar regions of the Arctic and Antarctic circles, the sunrise direction in all parts of the earth starts from the northeast and sets in the northwest.

Question 4: What does the summer solstice mean? What are the characteristics of summer solstice? What does summer solstice mean?

The higher the dimension, the longer the day and the shorter the night. The southern hemisphere is just the opposite, that is, the longer the night, the shorter the day. There is an extreme night phenomenon in the Antarctic circle. Because the farther the earth is from the tropic of cancer, the less heat the sun has, so this period of time in the northern hemisphere is summer, so June, July and August are summer, while the southern hemisphere is just winter.

What are the characteristics of summer solstice?

Although the summer solstice has the longest day and the highest sun angle, it does not mean that it is the hottest weather in a year, because the heat near the surface is still going on at the moment, not the hottest time. The really hot summer weather is calculated from summer solstice and autumn. It's probably from mid-July to mid-August, and the temperature is the highest this month.

Question 5: What does the summer solstice mean? What is the origin of the summer solstice?

At this time, the daylight hours in all parts of the northern hemisphere reach the longest in the whole year. For the Tropic of Cancer and its northern area, the summer solstice is also the highest day of the year at noon. During the summer solstice in Beijing, the daytime can be as long as 15 hours, and the height of the sun is as high as 73 32' at noon. On this day, the northern hemisphere received the most solar radiation, almost twice as much as the southern hemisphere.

Astronomical experts say that the solstice in summer is the turning point of the sun. After this day, I went back. The direct sunlight point moved southward from the Tropic of Cancer, and the daylight in the northern hemisphere became shorter and shorter day by day.

At the same time, after the arrival of the summer solstice, the stars in the night sky gradually became summer stars.

Solstice is the earliest of the 24 solar terms. In the 7th century BC, the shadow of the sun was measured by civil soil gauge, thus the summer solstice was determined.

" From summer to the sun, the sun directly reaches the northernmost part of the year, almost directly to the Tropic of Cancer (23 26' north latitude), and the daytime in all parts of the northern hemisphere reaches the longest in the whole year, and the farther north, the longer the daytime. For example, the daily length of Haikou in Hainan is a little more than 13 hours, Hangzhou is 14 hours, Beijing is about 15 hours, and Mohe in Heilongjiang can reach 17 hours. At the same time, for the Tropic of Cancer and its north, the summer solstice is also the day with the highest sun height at noon in a year. In Beijing, the height of the sun is as high as 73 32' at noon from summer to Sunday. On this day, the northern hemisphere received the most solar radiation, almost twice as much as the southern hemisphere. At this time, the southern hemisphere is in the middle of winter. okeycar/

In ancient China, the summer solstice was divided into three phases: "The first phase of staghorn dissolution; Second, wait for cicadas to start singing; Third-class Pinellia ternata. " Although elk and deer belong to the same family, the ancients thought they belonged to yin and yang. The deer's horn faces forward, so it belongs to Yang. On the solstice of summer, Yin Qi was born, and Yang Qi began to decline, so the front antlers began to fall off. However, the elk is cloudy, so it falls off at the corner from winter to Sunday; After the solstice of summer, the male cicada fluttered and sang because of Yin Qi's feeling; Pinellia ternata is a shade-loving herb, named after it was born in swamps or paddy fields in midsummer. It can be seen that in the hot summer, some yin-loving creatures began to appear, while positive creatures began to decline.

China folks divide 15 days from summer to the future into three "hours", usually the first three days, the middle five days and the last seven days. During this period, the temperature in most parts of China was high, the sunshine was sufficient, the crops grew rapidly, and the physiological and ecological water demand was high. At this time, the precipitation has a great influence on agricultural output, and there is a saying that "raindrops are worth tens of millions in summer solstice". In general, the precipitation in the middle and lower reaches of the Yangtze River and Huanghuai area can generally meet the requirements of crop growth. The Chronicle of Jingchu's Age says: "It rained on June 3rd, and the Tian family thought it was sweet, and the whole city congratulated each other." It can be seen that as early as 1000 years ago, people had a clear understanding of the characteristics of this rainfall.
