Aurora ice crystal pillars reappear in Genhe, Inner Mongolia. What is the reason for the formation of such crystal pillars?

Genhe City in Inner Mongolia is known as the Cold Pole of China. On the night of November 28, auroral ice crystal pillars appeared again in Genhe City of Lengji. These crystal pillars are colorful under the illumination of street lights. They are so beautiful that people can't help but admire the magic of nature. In fact, this is a very common natural phenomenon. It is also a type of light pillar, but it is called cold aurora or aurora ice crystal pillar in Genhe City. The reason for this kind of light beam is first of all because Genhe City once had the lowest temperature in history reaching minus 58 degrees, so it was awarded the title of China's Cold Pole. Recently, according to the meteorological observatory, the cold air activity over Inner Mongolia has been very active. Frequently, the lowest temperature in some areas ranges from minus 10 degrees to minus 5 degrees, and in the Hulunbuir area, the temperature is as low as minus 26 degrees to minus 13 degrees. Because the temperature in Genhe City is too low, there are many small ice crystals in the air, and the formation of aurora ice crystal pillars relies on the small ice crystals floating in the air. This columnar landscape is produced through the reflection of light. The colder the weather, the more small ice crystals there are in the air, and the more and brighter the light beams are reflected by the light. This is not the first time that aurora ice crystals have appeared in Genhe City. The first time they appeared was a week ago. For us, this is a very strange natural landscape, but for the local residents of Genhe City, it is also accustomed to it, because this kind of thing has happened almost every year in the past. This also shows that there will be a substantial cooling or even snowfall in the near future, which will be very detrimental to crops and livestock breeding. It is also hoped that local personnel can take countermeasures in advance to reduce the losses caused by the extreme cold weather. At the same time, it also attracted a large number of friends who love traveling and photography to come and watch. Many people paid attention to the colorful scenery under the refraction of the light, which made people feel as if they were in a fairy tale world. At the same time, this beautiful landscape has also promoted the development of local tourism.
