What are the three suns in Shanghai, Jiangsu and other places? Experts dispel doubts

"Three suns" is a phenomenon of "magic sun"

Many ice crystals in thin clouds at high altitude will refract when they meet sunlight.

Wang Sichao, a researcher at Nanjing Purple Mountain Observatory, Chinese Academy of Sciences, told reporters that the "three suns" are the illusion of the sun and have nothing to do with the end of the world. If the clouds are too thick, we can't see the "three suns".

Experts say that the smaller "sun" is actually a phantom of the real sun, and this special atmospheric phenomenon is rare. According to reports, "magic sun" is an optical phenomenon in the atmosphere-there are many hexagonal columnar ice crystals in the translucent thin cloud at the top of the sky, and sometimes they are neatly arranged vertically in the air. When the sun shines on these hexagonal icicles, it will produce a very regular refraction phenomenon, and it seems that there are many suns around.

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 day" phenomenon are actually more demanding. First of all, sunlight must pass through 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"

Dude, let me answer for you.

What are the three suns in Shanghai? Magical solar arc

There are solar halos and magic days over Shencheng today, which last for a short time. What most people see is the magical solar arc, also called zenith arc.

Magic solar arc is an atmospheric optical phenomenon formed by the refraction of sunlight, which is formed by the refraction of tiny ice crystals in high clouds about 6000-8000 meters from the ground at a certain angle. The surface of these ice crystals is curved, and the particles are smaller than salt particles. When the sun is under the sky and sunlight touches the flat surface of ice crystals, the light bends in each crystal, reflecting the seven-color spectrum unique to the rainbow, including red, orange, yellow, green, blue, indigo and blue-purple. Zenith arc is a normal atmospheric optical phenomenon. Circumzenithal arc is more common than rainbows in extremely cold regions, but it is rare in temperate regions.

How is it that there are many suns in the sky? The phenomenon you are talking about is the so-called magic day. Magic sun is an atmospheric optical phenomenon, because a large number of floating hexagonal ice crystals in the sky refract sunlight neatly, thus producing two or more virtual images of the sun on both sides of the real sun position. In 20 13, the phenomenon of magic sun appeared in Chifeng city of Inner Mongolia Autonomous Region and Chengde city of Hebei Province, and "five" suns could be seen at the same time.

What is the salt shortage in Shijiazhuang and Handan? Because it is rumored that iodized salt can prevent radiation, I buy it all, for fear that I can't buy it. Afraid of nuclear pollution in Japan, and there is no sea salt to eat. Anyway, the word is sick.

The most important thing at present is to find a way to eliminate everyone's panic. In fact, the Japanese were not so scared at this time, because they had too many things to do, and the post-disaster reconstruction did not give them a chance to panic. There is no need for us to snap up salt here. Let's really think about what we can do for the disaster area in the face of catastrophe.

On March 17, the National Development and Reform Commission issued an urgent notice, requiring all localities to immediately carry out market inspections and resolutely crack down on illegal activities such as spreading rumors to mislead people, maliciously hoarding, driving up prices and disrupting the market.

Recently, some places have been affected by rumors, which has led to the centralized purchase of edible salt. Some unscrupulous dealers took the opportunity to drive up prices and reap huge profits, and the masses reacted strongly. In order to ensure the market supply and price stability of residents' daily necessities and maintain market order, the National Development and Reform Commission issued an urgent notice, requiring local price authorities to take immediate action, carry out market price inspections, and resolutely crack down on illegal activities such as spreading rumors, maliciously hoarding, driving up prices and disrupting the market; Actively coordinate relevant departments, organize the supply of goods in various ways, ensure the market supply of edible salt and other commodities, and stabilize the market and price; Strengthen publicity and clarify false information and rumors in time. China is rich in daily consumer goods such as edible salt, and the supply is completely guaranteed. I hope that the vast number of consumers will rationally consume and buy, and will not believe in rumors, rumors or snap up.

How to close your eyes and have a small sun? In this case, I suggest you do an ophthalmoscope to see if it is caused by fundus lesions, and then treat it symptomatically.

How is the white spot on the temple? Patient: A few days ago, I found a white spot on my right temple. It feels slippery and painless. I don't know what's going on. What should I do? I'm a little worried about what harm it will do to me. I want to consult an expert. Expert: Judging from the symptoms you described, it is probably vitiligo. Temples are also common parts of vitiligo. The incidence of vitiligo is uncertain, and vitiligo can occur in all parts of the body. However, in order to avoid misdiagnosis, it is recommended to go to a regular vitiligo hospital for diagnosis. Vitiligo was treated well at first. If treated in time now, it may be cured in a short time, so don't miss the best opportunity for vitiligo treatment. Vitiligo is very harmful, which will not only damage your appearance, but also induce some diseases, which are harmful to your health. Must be cured as soon as possible.

What is it that there are two "suns" in the sky? This multi-day brilliant phenomenon actually belongs to the category of solar halo, which can be divided into solar halo and lunar halo. Will produce a halo, called halo in meteorology. Sometimes there are bright spots on both sides of the halo. When observing, you will feel such spots on the top, bottom, left and right, which are collectively called the same glow for several days in a row, or the same glow on the 4 th, 3 rd and 5 th.

The phenomenon of solar halo is very rare, which has aroused great interest. In fact, the halo phenomenon is somewhat similar to the common rainbow phenomenon in our daily life. Rainbow is because there are still many raindrops in the sky after heavy rain. These raindrops are like small prisms. After the sunlight is decomposed by prism, it becomes seven colors: red, orange, yellow, green, cyan, blue and purple, forming a rainbow. Solar halo is caused by refraction of columnar ice crystals. Besides solar halo, moonlight can also form lunar halo.

Solar halo is an astronomical phenomenon, which is caused by the cirrostratus composed of ice crystals at an altitude of 5000 meters. The ice crystals in cirrostratus will undergo physical changes such as refraction and reflection after being irradiated by the sun, which will decompose the sun into red, yellow, green, purple and other colors, thus a huge colorful halo will appear around the sun, which is called solar halo.

In winter, there is some water vapor. Because of the low temperature in winter, there is a lot of water vapor in the clouds under cirrocumulus or cirrostratus. Because it freezes when it is cold, such small hexagonal ice crystals are formed.

The magic sun appeared because ice crystals turned into countless small mirrors at the symmetrical points on both sides of the solar halo. These small mirrors reflect sunlight one by one, which makes them particularly bright, so there will be several virtual images of the sun, which is the strange "magic sun". If the weather conditions are right, we can sometimes see a magic sun at the sun's symmetrical point, and then five "suns" will appear in the sky.

The weather conditions required for the so-called multi-day luminescence phenomenon are harsh. First of all, there must be an appropriate amount of clouds in the sky, because such clouds are the material carriers that produce multi-day glow phenomena. Too few clouds can't form. If there are too many clouds, the light can be directly absorbed by the clouds, so it can't be photographed on the ground. The second condition is that there must be enough water vapor and a large number of ice crystals in the air. Ice crystals are generally hexagonal to produce light refraction. The other is that the demand for wind is relatively small and the atmosphere is relatively stable. Otherwise, regular ice crystals will be disturbed and regular light refraction will not be formed.

Jiangsu Huayang solar water leakage is how to return a responsibility? There are too many problems with solar water leakage. You mainly look at where the water leaks. There are two places: a water tank. Inlet and outlet pipes.
