Related differences between magic days

Zenith arc, also called magic sun arc, is an astronomical phenomenon in which a rainbow hangs upside down in the sky and its color direction is opposite to that of a normal rainbow. Its formation condition is that the sky is clear and there are few clouds. At the same time, sunlight can be refracted at a certain angle on tiny ice crystals in the clouds 6 100 -7625 meters from the ground. At the same time, the surface of ice crystals in clouds must be flat, and the particles are smaller than salt particles. 20 10 On July 20th, a beautiful scene suddenly appeared over Bournemouth Beach in the south of England: the sun was surrounded by a mysterious halo, just like a huge "eye" staring at the world from the sky. This is also a magical day, which is formed by hexagonal ice crystals in cirrus clouds in the sky refracting sunlight. Cirrus is a kind of high-altitude cloud, which is the highest cloud in the troposphere and consists of tiny ice crystals at high altitude. Usually, when the magic day appears, part of the sun will be blocked by cirrus clouds. The magic day usually appears when the sun angle is low, and this astronomical phenomenon will not appear at noon. Magic days are often called "solar halos" or "holidays".

This wonderful landscape made everyone on the beach stop to look up and was successfully captured by photographer Robert. "It was a fine day, and I went to the beach with some friends," Robert recalled. "At about 1 in the afternoon, I looked up at the sky, and at that moment I saw the halo around the sun. Aura is rare and often incomplete. Many people on the beach want to photograph the halo with their mobile phones, but it is not easy. I took this photo with an ultraviolet filter and a professional camera. That's really spectacular. "

Wilder, a local weatherman, explained, "The sun shines on ice crystals and a magical day is created. The main influencing factors include the direction and number of ice crystals and the number of cirrus clouds. These ice crystals act like prisms, bending sunlight and forming a halo around the sun. The shape of the halo is determined by the height of the sun. "

People usually think that this magical day is an auspicious sign. During the Battle of the Roses 146 1, Earl Edward, the eldest son of York family in England, later Edward IV of England of England, saw this spectacle, and then he encouraged the army to say that it was a good omen and finally won the battle. On June/KOOC-0/65438+/KOOC-0/October/KOOC-0/5, 2007, two "suns" appeared in the sky of Harbin. To the south of the normal sun, there is a darker "sun" shining in the clouds. At about 3: 40, the "sun" on the south side gradually darkened, turned into a rosy cloud and gradually disappeared. Magic days are common in the North and South Poles, but rare in Harbin.

Magic sun is an optical phenomenon in the atmosphere. There are many hexagonal columnar ice crystals floating in the translucent thin clouds in the sky, and occasionally they are arranged neatly in the air. When sunlight shines on these hexagonal icicles, very regular refraction will occur. When these many ice crystals are near sunrise or sunset, light enters from one side of the icicle and exits from the other two sides, resulting in reflection and refraction, and many suns are actually virtual images of the sun. There is a record of "five days of happiness" at most. Because the hexagonal icicles floating in the air are often arranged irregularly and cannot reflect the wonders of multiple suns, the atmospheric optical phenomenon of magic days is extremely rare. 20 1 1 year, "three suns" suddenly appeared in the sky of Jilin city, surrounded by rainbows, lasting about one hour. It is said that this strange sight is called "magic sun" and it is a special form of solar halo.

On October 20 1 1 10, there was a light snow in Jilin city. In the afternoon 1, three suns formed in the sky. The three suns are arranged in the order of large, medium and small, emitting a charming aperture, surrounded by two rainbows. The smallest sun emits red and yellow light, and the middle sun is rhombic, and the light emitted from each corner is different. At 20 1 1 year 1 month, three suns appeared in Changchun sky. Many Changchun citizens witnessed this rare natural wonder. Experts say that this phenomenon is called "magic day" and belongs to an optical refraction phenomenon of the atmosphere.

At about 13, there were two "small suns" to the left and right of the sun in the southwest of the sky, and there was a strong light at the top of the sun. The area of "Little Sun" is about110 of the sun. Two "little suns" and that strong light form a rainbow-like halo around the sun. After seeing this spectacle, many citizens took photos with cameras and mobile phones. Some netizens posted photos on QQ and blogs, and the title mentioned "Three Suns" in unison.

According to Zheng Liu, chief forecaster of Jilin Meteorological Observatory, "This natural phenomenon (magic day) is similar to the formation of a rainbow. Because the clouds are relatively high in winter, they are composed of ice crystals, which are arranged by chance to form a reflector with a special shape. When sunlight hits this reflector, it will be refracted and eventually form this natural wonder of' three suns'. "

Zheng Liu said that for Changchun, the natural wonder of "magic day" is rare not only in winter, but also in all seasons. In the morning, the reporter saw that there were two "little suns" on the left and right sides of the sun in the southeast direction of the sky, and three suns were formed in the sky. At the same time, the three suns also emit charming apertures, and the two "little suns" and that strong light form a rainbow-like halo around the sun.

According to the staff of Changchun Satellite Observatory of the National Astronomical Observatory of Chinese Academy of Sciences, the sight of three suns in the sky is a special form of solar halo, also known as "magic sun". This is an optical refraction phenomenon in the atmosphere, which is caused by the refraction of ice crystals in clouds. Probably because the clouds are very high in winter, composed of ice crystals, which are arranged by chance to form a reflector with a special shape. When the sun shines on this reflector, it will be refracted, eventually forming this natural wonder of' three suns'.

It is understood that this phenomenon has also appeared in Jilin Province. 13, at sunset in Stockholm, Sweden, there was a "magic day" spectacle.

According to the report, because countless ice crystals in the air refract sunlight, a "fake sun" appears on the left and right sides of the sun, and the three set each other off. The two solar halos outside the sun, 22 degrees and 46 degrees darker, are amazing.

It is reported that when water condenses at high altitude, a large number of hexagonal small ice crystals called "diamond powder" will be formed. When they fall from the sky, if they encounter sunrise or sunset, each ice crystal refracts sunlight like a microlens, forming a magical sun and halo. On the morning of July 5th, 20 12, some netizens found "two suns" hanging in the sky! He quickly photographed this strange astronomical phenomenon.

The phenomenon of "two suns" is not the first time in Jiaxing. On June 9, 65438, a two-day wonder appeared in the sky of Jiaxing. However, Jiaxing can't be seen everywhere. At that time, the "two suns" were arranged up and down, very close to each other. On the 5th, the "two suns" were distributed around, far apart. On September 12 and 20 12, the phenomenon of magic sun appeared in Wuhan. This is a post posted by a netizen on the Internet, which attracted many people to watch. From the photo, we can see that there are two suns in the sky. It is said that many people saw this strange phenomenon at that time, and many netizens and experts identified these pictures without PS. An astronomy expert in Hubei explained the magical sun. He said that the magical sun appeared because there were many hexagonal ice crystals in the sky, which were arranged very regularly. When the sun shines on these arranged ice crystals, the phenomenon of phantom yang appears.

In fact, the phenomenon of magic sun appears in many places, and there is no specific time, mainly because there are many very small hexagonal ice wafers in the clouds. When these ice disks are arranged neatly, especially when they are parallel to the ground, the sunlight will be refracted twice on these ice disks, and after refraction, these ice disks will usually deviate from about 22 degrees, so there will be two magic days of about 22 degrees on both sides of the sun. Sometimes magical days are colorful and beautiful because of the color and beauty of light. The small ice debris in these clouds can form many magical and gorgeous atmospheric optical phenomena, and the magical sun is one of them. Many citizens and netizens are interested in the three suns in Shanghai. In this regard, the Shanghai Central Meteorological Observatory explained that this is a meteorological phenomenon of solar halo and magic day, because there was a relatively high cloud over Shanghai that day, which was formed by ice crystals. Because the shape of ice crystal is similar to the physical "prism", it plays the role of splitting light and refracting sunlight, so it produces the magical solar arc, or zenith arc. Another expert said that this is only an atmospheric optical phenomenon with normal weather and has nothing to do with "doomsday theory".

In the morning, the temperature in Shanghai is low and the chill is obvious. As soon as Ms. Jin, who lives near the Bund in Shanghai, heard that there was a "vision" in the sky, she deliberately took a camera to shoot on the empty roof. "It seems that there are three suns in the sky at the same time, one of which is the largest, and there are two small suns on the left and right, wrapping the big sun in the middle." Ms. Jin, a pedestrian, said that a short rainbow hung upside down outside the arc of "three suns".

According to the Shanghai Central Meteorological Observatory, the magic solar arc is an atmospheric optical phenomenon formed by the refraction of sunlight. It is formed by sunlight refracting at a certain angle on tiny ice crystals in high clouds about 6000 to 8000 meters above the ground. The surface of these ice crystals is curved, and the particles are smaller than salt particles. When sunlight touches the flat surface of ice crystals, the light bends in each crystal, reflecting seven color spectra unique to the rainbow, including red, orange, yellow, green, blue, indigo and blue-purple. This normal atmospheric optical phenomenon is more common in extremely cold regions than rainbows, but it is rare in temperate regions.

Usually, "magic day" doesn't last long, ranging from a few minutes to dozens of minutes. Sometimes it appears around 5:30-6:00 or 9: 00 in the morning, and sometimes it appears at night. Experts say that the conditions of the "magic sun" phenomenon are actually very harsh. First, sunlight must pass through the high-altitude clouds with ice crystals. Secondly, the clouds should be thin and have good light transmittance. "The most important thing is that the angle between the sun and ice crystals and the observer should be just right. As long as there is a slight deviation, it is difficult to find the wonder of' magic day'. " (chongqing morning post reporter Gong Li reported on June 18 15: 10) On the morning of June 18, two "suns" appeared in Chongqing College of Humanities and Science, which attracted many students to watch. However, the Chongqing Meteorological Bureau responded that this is actually a "magic day" and an atmospheric optical phenomenon. "Chongqing is surprised by two suns, a sign that the temperature is against the sky?" At 8: 37 on June 5438+08, the netizen "Wheat field _ pineapple bag to be dipped in hot sauce" saw this amazing scene at the entrance of the canteen of Chongqing College of Humanities and Science. She photographed it with her mobile phone and posted it on the Weibo, which became a hot topic in Chongqing, which was sunny and hot.

From the picture, the sun is high in the sky as usual. Different from the past, a luminous body of similar size appeared next to it at the moment, which also gave off dazzling light. Seen from a distance, the two bright spots are separated by a certain distance and hung side by side in the sky.

Subsequently, many netizens said that they also saw this phenomenon. For a time, Chongqing's statement of "two suns" spread rapidly on the Internet, attracting comments from netizens.

The reporter then contacted the photographer of the picture, "Wheat field _ pineapple bag should be dipped in hot sauce", who is a student of Chongqing College of Humanities and Science. According to her introduction, at 8: 30 on June 5438+08, my classmates and I came out of the dormitory to prepare for class. When she walked to the door of Zhiyuan canteen, she found that a dozen students stopped to watch and screamed from time to time.

"God, there are two suns in the sky." "Wheat field _ pineapple bag should be dipped in hot sauce" overlooks everyone's sight. Through the cracks in the leaves, she clearly saw two bright spots in the sky. "This is amazing, this is my first time."

Two suns once caused a riot. At that time, when the students rushed to the classroom, almost all the passing students raised their heads, then picked up their mobile phones and slapped the sky. According to the introduction of "Wheat field _ pineapple bag should be dipped in hot sauce", some students have discovered this strange weather phenomenon around 7:40.

What happened to the two suns? Netizens are talking about it. 12: 13, Weibo, the official of Chongqing Meteorological Bureau, confirmed that "magic sun" appeared in the morning of Chongqing 18, which is actually a very common atmospheric optical phenomenon. It is understood that "magic day" usually appears from 5: 30 to 6: 00 or around 9: 00 in the morning, and it will also appear at night. There are certain conditions for the emergence of "magic day": 1, there are clouds at the top, and only when there are clouds will ice crystals form; 2, the clouds should be thin, and the light transmittance should be good, so that sunlight can be refracted; 3. The angle between the sun and the ice crystal and the observer should be just right, and it can't be seen if it is slightly off.

Meteorologists said that the recent high temperature was caused by the influence of subtropical high, and it was not directly related to magic days.

The reporter's investigation found that "two suns" appeared in the sky of Jiaxing, Zhejiang Province on July 5, 20 12. 20 12 12 10 in February, "three suns" appeared in Shanghai. These are all "magic days" phenomena.

"Hou Yi, your mother asked you to go to Chongqing to shoot the sun." The wonders of the two "suns" remind people of the legend that "Houyi shoots the sun". Although it is an optical phenomenon, netizens still take this opportunity to entertain themselves. "A sun is hot enough. We have two in Chongqing. Do you dare to compare the high temperature with us? " Netizen "Tang Tang's Text" commented that in front of the two "suns", the ground roast chicken eggs, the chart of the thermometer ... everything is very fragile. Netizen "Yan Xun" even wrote a passage about Weibo, poking fun at the phenomenon of "magic sun": "According to relevant sources, the other eight (suns) will appear in all directions later today, when the suns will be reunited at high altitude in the mountain city and enjoy family happiness. According to reliable sources, Houyi's quiver spontaneously ignited this morning. "

Magic sun is an optical phenomenon in the atmosphere. There are many hexagonal columnar ice crystals floating in the translucent thin clouds in the sky, and occasionally they are neatly arranged vertically in the air. When sunlight shines on these hexagonal icicles, very regular refraction will occur. 2065438+2005 65438+2065438+20051October 23, a rare beauty was surprised over Siberia, Russia. In the video pictures taken by people, it seems that three suns appear in the sky at the same time, which can be seen from the Urals to the Russian Far East. Sometimes it is regarded as an ominous omen or indicates that the winter has come.

Experts explained that this optical effect is produced by sunlight reflected by ice crystals suspended in the air, which is called magic day.

Local officials said that there were many traffic accidents in Russia because some people were scared by the "three suns" appearing in the sky.
