Just a few days ago, affected by the cold air, Henan Sanmenxia ushered in a snowfall, the minimum temperature dropped below 0 ° C, shortly after the snow stopped, the snow on the red tiles of the sidewalk showed an incredible shape, curious netizens deliberately used their mobile phones to take a spectacular picture of the time.
The appearance of thousands of "snow steamed buns" in Sanmenxia, Henan, is the artist's creativity?
The footage showed rows of dotted snow on the red tiles of the sidewalk, which were of the same size and neatly arranged, thousands of them, shaped like chubby white steamed buns, plus just about the same size as the steamed buns, some people simply called them "snow buns".
Seeing such a neat "snow steamed bun", people are reluctant to get off their feet, for fear of destroying the perfect picture, which also raises a question for everyone, how did so many "blood steamed buns" come from, is it a creative work after the artist's sudden imagination? Or is it the masterpiece of some boring person?
As soon as the spectacular picture of "snow steamed buns" was published, it ushered in a wave of hot discussion, some netizens said that there must be demons when things go wrong, and some netizens said that Ruixue Mega Year, which is a good omen for the New Year, in fact, these blood steamed buns are naturally formed, not made by people, but nature cleverly borrowed artificial objects.
How does nature cleverly use man-made objects to make "snow buns"?
Careful friends may have found that the red floor tiles shown on the screen have multiple holes, the red floor tiles are square, but there are multiple semi-circular holes on the side, after the local bricks are laid, then there will be rows of round holes in the floor tiles, and the bottom of the round holes is the uneven surface.
"Snow steamed buns" are produced in the round hole position, in fact, the principle is also very simple, after a snowfall, the snow on the surface of the floor tiles melted, only the snow in the round hole position did not melt, it looks like a chubby steamed bun, very tempting, it is estimated that a few more looks will be hungry immediately.
The reason why the snow melting rate of the surface area of the floor tiles is far higher than the snow melting rate of the round hole position is mainly due to two aspects, one is that the specific heat of the floor tiles is much larger than the soil, and the other is that the surface of the floor tiles is much smoother than the surface of the soil.
Floor tiles are larger than heat, then its heat absorption capacity is in, I believe many people must have experienced, especially in winter, floor tiles are much cooler than wooden floors, but iron is colder than floor tiles, which is because the reason for the larger than heat, larger than heat also represents the ability to exotherm in, so the heat dissipation capacity of floor tiles is greater than the surface.
Although the sidewalk floor tiles have a non-slip design, not very smooth, but compared with the uneven surface, much smoother, the smoother it means that the contact area with the snow is larger, can transmit heat to the snow faster, the snow melts faster, these two reasons lead to the ground tile snow melting speed is far more than the surface snow melting speed.
In the cold winter, the air temperature is lower than 0 ° C, but the surface temperature is not necessarily lower than 0 ° C, the temperature of the floor tiles close to the surface is consistent with the surface temperature, when the snowfall is not large, the snow on the floor tiles will melt off on the spot, after the snow stops, the floor tiles can not see the snow, but the round hole snow is still there, becoming a "snow steamed bun".
"Snow Steamed Buns" have been photographed many times
On April 5, 2018, a friend photographed the landscape of "snow steamed buns" in a parking lot in Yanqing, Beijing, which were like steamed buns that had just come out of a large steamer, with a swollen surface and the same size. Later, many people's mobile phones were brushed by "snow steamed buns", so there was the name "snow steamed buns".
In fact, before 2018, there must be often "snow steamed buns" landscape, but there is no name, in short, the emergence of "snow steamed buns" is related to the three factors of round hole artificial floor tiles, snowfall size, and air temperature on the day, so this is nature making "snow steamed buns" by means of artificial objects.
summary
In short, "snow steamed buns" is a normal natural phenomenon, we do not need to over-interpret, all say that nature is a ghost, see the "snow steamed buns" in front of the screen, have to serve, nature has taken artificial objects into account, what else do you not believe?
