On December 26, the light column phenomenon appeared in Xilin Gol League of Inner Mongolia Autonomous Region. The light column phenomenon appeared from 19:30 and lasted until 21:30. At that time, the outdoor temperature was minus 20 degrees Celsius. It was sunny and windless, which was very beneficial to the public. The lighting of the building is reflected as a colorful column of light, making people feel like being in a fairy tale. Previously, some media claimed that it was a Japanese column phenomenon, but there was a meteorologist @大脸撑 in a small chest that explained a similar phenomenon last year, it is not the Japanese column. The principle is almost the same. The plate-shaped ice crystals in the cold atmosphere reflect the sunlight, forming a beam of light above and below the sun. This is the sun pillar of the sun pillar. Reflecting the moonlight is formed by the moon pillar. Xilin Gol, which is formed by the neon lights of reflective lights, called the light pillar. When the ice falls from the high-rise clouds, it sometimes forms a flat plate, which is shaped like some ice crystals. The air resistance makes these ice crystals almost horizontal when they fall to the ground. At this time, the sunlight is also emitted from the vicinity of the horizon. The sunlight reflected by the ice crystals is almost completely vertical, resulting in a solar effect. When the weather is cold and the sun just rises or falls, the falling ice crystals reflect the sun and produce a rare beam of light.
