Initial data
Today, on December 1, a resident of Avtograd posted a post on the Internet with unusual photos of the Volga River. They depict ice circles covering the surface of the water.
" On the first day of winter, I saw an unusual drawing on the Mother Volga," the citizen said.
What is the reason for the appearance of a natural pattern remains a mystery. However, under the author's entry, many users suggested that the circles were formed due to emissions into the water, which soon froze and formed a beautiful picture. Others reacted to this with humor and considered that the drawing was left by alien guests.
Hypotheses
The formation of ice and snow over the pond
On the ice surface of the reservoir formed circles of different diameters. The scientific explanation for the formation of ice circles is that the bend of the river or over the underwater keys accelerated the flow of water crushes and twists formed ice crust, forming an ice disc. Then the rest of the ice on the surface of the water involved in rotation and sticks to the disk, which not only increases its size, but also gives a perfect round shape. Occurs mainly in waters with fairly strong current.
Investigation
Most likely, these are ice "saucers", also known as "pancakes". Here are some news with pictures as an example.
News: An unusual phenomenon of nature was noticed near Pskov
In the Plyussky district of the Pskov region, a local resident Natalia Alekseeva noticed an unusual phenomenon of nature - ice "saucers" formed on the water due to frost, also known as "pancakes". She shared the photos with the regional newspaper "Plyussky Krai" in VKontakte.
The pictures show a pond on the surface of which "lies" a large number of miniature disks with bordered sides. Such a "pancake" ice near Pskov arose due to the sharp cold, the active flow of water and wind.
In the comments, netizens were surprised by what they saw.
News: Rare "ice pancakes" formed on rivers in Scotland and England
Dozens of amazingly perfect circles of ice, known as "ice pancakes," have appeared on the surface of a Scottish river after temperatures in the UK unexpectedly plummeted.
Callum Sinclair, project manager of the Scottish Invasive Species Initiative (SISI), spotted the stunning round ice floes on December 9 on the River Bladnoch in Wigtownshire, Scotland. Photos of unusual ice pancakes made by Sinclair were posted on SISI's Twitter page on December 13, along with a short video showing how the ice discs collide with each other and are washed downstream by a fast current.
News: Ice floes in the form of pancakes appeared on the river in Birobidzhan
The Biru River, flowing through Birobidzhan, was covered with ice of an unusual shape. Eyewitnesses filmed a kind of ice "pancakes" accumulated on the surface of the reservoir, and posted the footage on social networks. Some compare the shape of ice to pizza.
News: Maslenitsa: how does nature prepare ice pancakes?
A wide Maslenitsa is marching across Russia. This year, Shrovetide week began on March 8. The traditional symbol of Maslenitsa is pancakes. Fragrant, round and rosy, they take center stage on the table.
But did you know that nature also knows how to cook pancakes? Only not hot, but icy!
Ice pancakes are a fairly rare hydrometeorological phenomenon. It can only be observed in cold seas, rivers, or lakes.
Ice pancakes are formed in two ways. In the seas and lakes, the waves beat the pieces of ice to each other. The result is an extensive shape with rounded edges.
