Why do two suns appear above Shijiazhuang? Is this phenomenon common?
The appearance of two suns in the sky over Shijiazhuang was not common before 2020, but in 2020, it is an extremely common thing. Multiple suns appear in the sky. This phenomenon is called "heliotrope". It is caused by refraction of a large number of columnar ice crystals in the fog. It may be that the temperature dropped relatively early this year, and a large number of sun dog phenomena occurred across the country. In the past, "solar magic" occurred many times in Mohe, Heilongjiang, Inner Mongolia and other places. 1. Two suns over Shijiazhuang
On the morning of October 28, many citizens over Luquan City, Shijiazhuang took videos of two suns appearing in the sky. Many people are curious and don't know what's going on. In fact, this phenomenon is called "phantom sun". If you frequently surf the Internet or read the news, you will find that similar incidents have occurred in various regions this year. The main cause is refraction caused by the fog, which may be caused by cooling. A large number of columnar ice crystals appear in the fog. These ice crystals are like prisms that refract the sun very regularly. We see "two suns", which is the effect of refraction. 2. It’s very common in 2020
In previous years, this phenomenon would have been unusual, but in 2020 it can only be called “common”. Some time ago, a similar phenomenon occurred over Mohe, Heilongjiang, except that "3 suns" appeared at that time. Before and after the Mohe Sunrise Incident, similar phenomena occurred in Inner Mongolia, Northeast China, Wuhan and other regions. The difference between them is the number of suns and the time they appear. Generally, sundogs will appear at 5 a.m. or 9 a.m. and last from a few minutes to dozens of minutes. 3. It may be due to the impact of cooling
The cooling rate in 2020 is relatively fast, and many areas have been affected. Even migratory birds are showing signs of migrating early. When the temperature drops rapidly, ice crystals may appear in the fog. The appearance of a large number of ice crystals may reflect the sun dog. Of course, the temperature is dropping rapidly, which is within the normal range. There is no need to make a fuss after reading some fake news on the Internet about the coldest weather in decades.
