Contrary to popular belief, as long as the ground has an insulating blanket of snow, the ground is almost always warm–near freezing–even with … It’s located along the expressway in a grove of trees. How faceted snow is formed: Faceted snow forms from large temperature gradients within the snowpack. Snow depth is also shown where snow accumulates. Curve 3 came from a different location where the snow is "heavier", or wetter, when it falls and is more likely to be subjected to warming spells than is the snow from the other regions. noun. "Tricks of the trade" include taking "lower slope" readings halfway up the mountain, or simply measuring depths in areas where snow has been piled up. Snow Depth The combined total depth of both the old and new snow on the ground. Especially when the snow cover consists of many different and especially thin layers of snow, there's a big chance of depth hoar, with hard snow layers increasing that chance.
