According to related reports, on August 8, there was a spectacle of warm night lamp posts over Pingtan, Fujian. The whole scene is like the last colorful tear in the sky, and it is like a colorful lamp post hanging in the night sky. It looks really mysterious and spectacular. It lasted for several hours. Meteorologists say that such a situation as a warm night lamp post can not be met. Warm night lampposts last for a long time and cover a wide range, appearing in the night sky of Pingtan, Xiamen and Lianjiang, among which Pingtan is the most spectacular. It's ridiculously beautiful Is it too shocking to the magic of nature? Yesterday, a large group of warm night lampposts detonated Fuzhou WeChat circle of friends. The photographer of this group of photos is Xu Chen, director of the Provincial Astronomical Society and a star photographer in Fuzhou. At 9: 30 in the evening, I was lucky to meet a spectacle. At night, bundles of colored light beams hang in the air, just like the market in the sky. According to Xu Chen, there are always three places in Fan Chuanjiao's sky, among which the lighthouse is the most spectacular. It is understood that in May this year, there was a warm night light sticker in Xiamen, which lasted about 1 hour. In contrast, the warm night lampposts reappeared in Fujian this time have a wider range and a longer time. The wonders of Cape Fan Chuan lasted from 9: 30 that night to around 4: 00 the next morning. According to the staff of the Meteorological Observatory in Pingtan Comprehensive Experimental Zone, the temperature in Pingtan was high the night before, and there were high clouds and ice crystals in the air. The wind at high altitude is small, the weather is basically calm, and the ice crystals in the clouds are arranged neatly, which creates conditions for the formation of warm night lampposts. At that time, the clouds were like mirrors, reflecting the lights on the ground in the night sky, and finally forming a spectacle. It is especially lucky to enjoy weather phenomena such as warm night lampposts. It is understood that compared with the cold night light columns in cold areas, the warm night light columns in southern areas are even rarer and very rare. Visible to the naked eye, lasting for a long time, or even shorter. People who can enjoy it can be said to be particularly lucky. Cherish this hard-won opportunity.
