The aurora ice crystal column reappears in Genhe, Inner Mongolia. What is the reason for the formation of this crystal column?

Genhe city, Inner Mongolia is called the cold pole of China. 165438+1On the night of October 28th, the aurora ice crystal column appeared again in Lengjigen River. These crystal pillars are colorful and breathtaking under the illumination of street lamps, which makes people admire the magic of nature. In fact, this is a very common natural phenomenon, and it is also a kind of light column, but it is called cold aurora or aurora ice crystal column in genhe city. This kind of light beam appeared because genhe city was awarded the title of China Cold Pole because the lowest temperature in history reached minus 58 degrees. Recently, according to the Meteorological Observatory, the cold air activity over Inner Mongolia is very frequent, with the lowest temperature in some areas ranging from minus 10 to minus 5 degrees, and the temperature in Hulunbeier as low as minus 26 degrees to minus 13 degrees. In genhe city, because the temperature is too low, there are many small ice crystals in the air, and the formation of the aurora ice crystal column depends on the floating small ice crystals in the air, and this columnar landscape is produced by light reflection. The colder the weather, the more small ice crystals there are in the air, so the more beams reflected by light, the brighter it will be. It is not the first time that aurora ice crystals have appeared in genhe city. It first appeared a week ago. For us, this is a strange natural landscape, but for the local residents in genhe city, it has become accustomed to it, because it happens almost every year. This also shows that there will be an obvious cooling or even snowfall in the near future, which is very unfavorable to crops and animal husbandry. I also hope that local people can take countermeasures in advance to reduce the losses caused by extremely cold weather. At the same time, it also attracted a large number of friends who like traveling and photography to watch, and a lot of attention was colorful under the refraction of lights, which made people feel like they were in a fairy tale world. At the same time, this beautiful scenery has also promoted the development of local tourism.
