Cause of formation of cold night light beam in Xinjiang
In winter, in Hehe Village of Altay Mountain in Xinjiang, the low temperature can reach MINUS 30 degrees Celsius, and it will be even colder at night.
65438+1October 1 1 Around 4 a.m., a rare and interesting natural wonder "Cold Night Light Column" appeared continuously in Harmony Village in extremely cold mountainous areas. Like a sword, colorful light beams go straight to the stars, just like a sci-fi blockbuster!
"Cold night light column" is a reflection principle phenomenon in nature, which only appears on very cold nights. Its beauty is comparable to aurora, and its formation depends on the reflection of a large number of ice crystals (snowflakes) in the air.
According to reports, snowflakes are hexagonal, and light is reflected like a mirror through these ice crystals, and then passed to people's eyes. What people see is the virtual image of the upward reflected beam. The colder the place, the more ice crystals in the atmosphere, and the stronger the reflection.
Where is the cold night beam?
Although for people in temperate and tropical regions, this magical astronomical phenomenon is basically invisible for a lifetime (even a hundred lifetimes). But cold night lampposts are not uncommon in extremely cold areas, such as Xilinhot and Genhe in China, and the Inner Mongolia and Daxing 'anling they represent. These extreme northern places appear many times every year.
In addition to the recent cold night light column, on New Year's Eve in 2008, another kind of harmony appeared in Altay, the birthplace of the cold night light column phenomenon in China. According to the photographer and the staff of the local scenic spot, this is actually not the first time to see it, because the unknown has been hidden in the extreme cold of Kanas.
The colder the place, the more ice crystals in the atmosphere, and the stronger the reflection. In the most extreme cases, the light beam is as clear as a knife, reaching the zenith, and even "drawing" the street map of the town in the sky!
Compared with the peak intensity, Leng Ye beam phenomenon can also expand its territory in types. In addition to simple columns like pillars, there can be complex columns with more surprising shapes on cold nights.
The discovery of' cold night lamp post' on New Year's Eve broke the long-standing record blank of complicated cold night lamp post in China.
