Crystalline structure of snow
WebA half century later, even books for young people were saying flatly that the crystal structure of snow resulted from some kind of molecular arrangement of molecules. By then, we knew that snowflake crystal … WebJan 1, 2014 · Snow k T is very strongly dependent on snow structure, because diffusive thermal transport mostly takes place through the network of interconnected ice crystals (Sturm et al., 1997). Fresh snow k T can be as low as 0.025 W m −1 K −1 , that is, more insulating than styrofoam, while very hard windpacks or melt-freeze layers have values …
