According to media reports, on January 10 and 8, the surface of liaoheba in Heping Township, Faku County, Shenyang, formed a mysterious ice circle that has been rotating all the time. According to local villagers, the rotating ice circle can accommodate about three cars, and has been rotating at a constant speed on the river. It is understood that this phenomenon is very rare in the world, generally only in the Arctic, Scandinavia and Canada and other high-dimensional areas.
The reason for this rotating ice circle is that at the corner of the river, the accelerated flow of water produces a force called "rotating shear", which cuts off the ice and then slowly rotates it. The cut ice and the surrounding ice rub against each other to form a positive circle.
This is not the first time in China. It is reported that Chen Jingchao, a photographer from Huludao City, Liaoning Province, came to Jieshi scenic spot near Suizhong Binhai Economic Zone as usual to shoot the sunrise on the sea. He found that there are countless "Ice Circles" of different sizes on the sea ice surface, some of which are still connected in spectacular circles. As for the formation, experts speculate that this kind of vortex may be caused by the different density of the sea water after the sea ice is frozen, resulting in the vortex caused by the circulation of the sea water, just like dropping a brick into the water, resulting in ripples.
Some experts also say that this situation is actually the impact of underwater gas resources, resulting in vortex in the water, which makes the rotating ice circle on the water surface.
