Discovered in the river – Ice disc in China spins as if by magic

Date:

A circular ice floe with a diameter of about 20 meters, slowly rotating counterclockwise and floating in a river, is currently causing a stir in China’s Inner Mongolia.

A photographer spotted the ice disk, which spins like magic, a few days ago in the Chuo’er River near the city of Hulun Buir in the Inner Mongolia Autonomous People’s Republic.

Rare but completely natural phenomenon
According to experts, a kind of vortex effect, caused by a special current in the river, is the reason for the round shape of the ice floe. It is said that this is a rare but completely natural phenomenon.

Years ago, Belgian scientists explained the rotational motion of such round floes with temperature differences in the water directly beneath the ice disk.
