Snow crystal morphology
WebThe Snow Crystal Morphology Diagram was discovered in the 1930s by Japanese physicist Ukichiro Nakaya and his collaborators, and it is sometimes called the Nakaya Diagram for this reason. They grew snow crystals in their cold lab at different temperatures and … The largest snow crystal ever photographed (to my knowledge) is this monster. … This is summarized in the Snow Crystal Morphology Diagram shown on the right. … The six corners of a snow crystal grow a bit faster because they stick out farther into … A smaller book, the Field Guide describes all the different types of snowflakes and … At left is a photograph of a designer snowflake-- a real sliver of ice, grown … WebOnce on the ground, snow crystals metamorphose into different shapes, influenced by wind, freeze-thaw and sublimation. Snow on the ground forms a variety of shapes, formed by wind and thermal processes, all subject to formal classifications both by scientists and by …

WebFor both treatments, we measured with a dedicated snow tribometer the friction coefficient µ on compacted snow at different temperatures (−10 °C; −5 °C; −3 °C) for a gliding speed range between 1 and 6.1 ms −1. We compared the obtained µ values with those of untreated AISI 301H plates and of stone grinded, waxed UHMWPE plates. WebOct 22, 2009 · Snow crystal growth is typically dominated by the kinetics of molecular attachment in combination with the already mentioned transport effects: mass diffusion, which carries water molecules to the growing crystal, and heat diffusion, which removes the heat generated by solidification.
