What rare astronomical fantasies have appeared in the sky?

? On April 27, 2008, rocket noctilucent clouds appeared in North China and other places, forming a tail cloud in the upper atmosphere. The formation of noctilucent clouds requires extremely low temperature, and only the middle atmosphere can have such sufficient low temperature conditions in the weeks around the summer solstice. In September 1 1, Rongcheng, Shandong, a dragon-sucking (tubular cumulonimbus) tubular machine appeared in the sky. This is a rare cloud structure, comparable to the top ten strange clouds in the world, but it is not rare in summer. Because its appearance is rare, often without warning, it suddenly appears and suddenly disappears!

On July 26th, cirrus, one of the top ten strange clouds in the world, also appeared in Henan. A huge impact? Yun Qi! ! Because of its low altitude, it can only be seen at sea, but on July 16 in Baoding, Hebei Province, it passed through Gaobeidian area and swept across Langfang Yongqing, and it was recorded as far away as Tianjin Wuqing and Yangliuqing, sweeping at least hundreds of kilometers, which was super spectacular! ! There is also 65438+February 65438+April, in the cold night of Qinghai tea card, which really created the atmospheric phenomenon, the first aura of single post reading in history. Such a colorful halo, such a wonderful and complicated cold night light beam, its light intensity is super strong and varied, almost stronger than the light beams that rushed to the zenith and climbed to new heights forever. They have many tricks, but we admire them! !

There is also a smile from the sky in Beijing, also called the eye of God. On the afternoon of June 65438+1October 65438+March, 2020, she presented circumzenithal arc in a residential area near Beiwa Road, Haidian District, Beijing. It hangs in the sky like a rainbow, very beautiful, bright and beautiful, attracting many people to watch. Dome arc is an optical phenomenon that looks like a rainbow, but it is different from a rainbow. It is formed by the refraction of sunlight through ice crystals from the horizontal direction. ! There are many strange phenomena, which are endowed by nature, so we should protect nature well! !
