Natural Phenomena That Seem to Break the Laws of Nature
Snow donuts, also known as snow rollers, are a rare meteorological phenomenon in which large cylindrical snowballs form naturally in certain conditions. They are created when a thin layer of ice forms on the surface of the snow, followed by a layer of loose, wet snow that is just sticky enough to adhere to the ice. If the wind is strong enough to move this layer of wet snow, but not strong enough to break it apart, it can roll along the surface and gather more snow as it goes, forming a cylinder-shaped snowball that can be several feet in diameter. The resulting snow donut may have a hollow center and can have a ring-like shape due to the layers of snow that have been rolled up. Snow donuts are quite rare and require very specific weather conditions to form. They are typically found in open areas with little or no vegetation, such as fields or meadows, and are most commonly observed in regions with cold, snowy winters and high winds.
