Despite the fact that snowflakes can be very diverse in their structure and forms, it turns out, their general structure is not as unique as we used to think about it. At least at least, the process of snowflake formation is almost the same. Mechanical Engineer Adrian Bejan of Duke University demonstrates in in his new video, exactly how a single snowflake is formed. It turns out that every snowflake begins its “life” in the cloud, located high in the sky. Initially, it looks like a tiny specks of ice around which over time a small ball of ice. It would seem paradoxical, but this ice ball its temperature is slightly warmer than the surrounding air atmosphere, so the formed dense bead is practically half of your way to be in the same state. However as soon as the ice ball reaches warmer air layers atmosphere, from a piece of ice begin to form and sprout outward rays, forming the familiar beautiful snowy for all of us a snowflake crystal, necessarily having a hexagonal shape. Moreover, the closer the distance from the snowflake to the surface of the earth, the its form becomes intricate. Depending on humidity air temperature, as well as atmospheric pressure and volume of snowflakes, the most unusual ones may appear on its rays, intricate processes. Since the tips of the ice needles are snowflakes continue to form their ledges on their own (and this continues right up to her landing), in the end it leads to a magnificent filigree the structures of each of its scales. That is why during the snowfall we we can enjoy the magnificent gallery of snowflakes, where the only and unique Tiny, but such amazing ice sculptures.
