What happened to the ice circles frozen out of Shenyang and Beijing in the cold wave?

Recently, a rotating ice ring appeared on the Shenyang River. The ice ring is too big to hold three cars. This spectacle was not only on the hot search list, but also reported by CCTV. The rare spectacle scene was exposed, which was very spectacular. How is this rotating ice ring formed? Let's have a look. What is the vortex ice ring on Shenyang River? On June 65438+1October 10, a mysterious rotating ice ring appeared on the Liaohe River in Faku County, Shenyang City, which aroused the onlookers of the local people. Some villagers said that they had been here for decades and saw such a spectacle for the first time. The scene was so spectacular that the onlookers said it was incredible. It is understood that this ice ring is very large and can accommodate three cars at the same time. More importantly, the huge ice circle will rotate rapidly by itself, and the surrounding water will flow, just like a piece of Yu Pei in Liaohe River, which is very beautiful.

Ice ring wonders are very rare in the world, and usually only appear in the Arctic, Scandinavia, Canada and other regions. It is rare in China. According to previous reports, Chen Jingchao, a photographer from Huludao City, Liaoning Province, accidentally photographed many ice circles of different sizes on the surface of sea ice when shooting the sunrise in the coastal economic zone. The scene is also spectacular. What is the vortex ice ring on Shenyang River? The formation of this kind of ice ring is mainly because at the corner of the river, the acceleration of water flow will produce a force called rotational shear, which will cut off the ice. The ice cubes will slowly rotate, and the cut ice cubes will rub against the surrounding ice cubes to form a round plate. The reason why the ice ring rotates at a constant speed is that when the vortex in the water rotates in a circle with the diameter and size, the ice ring will also rotate with it. The formation of this vortex is due to the different density of seawater after sea ice freezing, which leads to seawater circulation.

Ice ring phenomenon is very rare in the world, and usually only appears in the Arctic, Scandinavia, Canada and other regions. At the corner of the river, the acceleration of the water flow produces a force called rotational shear, which cuts the ice layer and then slowly rotates. The cut ice rubs against the surrounding ice to form a circle. When the vortex in the water rotates in a circle with a certain diameter and size, the ice and floating impurities in the water are evenly distributed in the vortex, forming a mysterious regular round ice layer. The largest ice ring found is over 500 feet in diameter. In addition, ice rings with different diameters were found at different places and times.

The diameter of these ice rings ranges from 10 m to 23 m, which has become the focus of attention of many Huludao citizens. According to relevant data, this spectacle is rare in the world and can only appear in the Arctic, Scandinavia, Canada, Russia and other regions. Experts speculate that this vortex may be caused by the different density of seawater after sea ice freezes, which leads to the circulation of seawater, just like throwing bricks into the water, causing ripples. However, a German media reported that Russia's ice circle may be caused by the vortex of water flow caused by underwater natural gas resources.
