Snow Facts: 21-25 | Graupel explained
21. Graupel is often confused with hail or ice pellets or even small hail. However, graupel is different from all three.
22. There are certain atmospheric conditions where snow crystals can actually come in contact with supercooled water droplets. These supercooled water droplets can stay in liquid form even at temperatures as low as -40°C.
23. The moment the snow crystals or ice crystals come in contact with these supercooled water droplets, the droplets freeze right on the surface of the ice crystals as a result, the crystals keep growing though the process known as accretion.
24. When process of accretion continues and reaches a stage where it becomes virtually impossible to identify the actual snow crystals, they are known as graupel.
25. Graupels usually have a diameter of 2 to 2 millimeters. Graupels are lumpy masses that may look like hail but they crumbly and softer and may fall apart when touched.
Snow Facts: 26-30 | Polycrystals explained and a few fun facts
26.These are basically snowflakes that are made of many individual snow crystals (snowflakes or ice crystals) that may vary in size and orientation.
27. The individual snowflakes in a polycrystal may be of different type and shape.
28. Snow Fun Fact #1: Did you know that the saying that no two snowflakes can be identical is actually a myth? It was true until in 1988, a scientist in Wisconsin managed to find two identical snowflakes.
29. Snow Fun Fact #2: Did you know there is something called Thundersnow? This is a condition in which lightning and thunders take place during snowing.
30. Snow Fun Fact #3: Did you know that the largest snowflake reported till date is 8 inches thick and 15 inches across? It has a Guinness World Record. It was found in Montana’s Fort Keogh in 1887. The exact date was January 28!
That completes our article on snow facts. However, we are far from being done. There’s a lot more to speak and we will do so in subsequent articles on snow facts. Until then…
