WebBasal facets are a common type of persistent weak layer that forms at the base of the snowpack. As basal facets evolve into larger, more striated grains, they are called depth hoar. In its most advanced form, depth hoar can be found in chains of cup-shaped crystals up to 10 mm in size. These weak layers are frequently associated with Persistent ... WebMeasurements of snow hardness in snow pits are commonly made using the hand test, whereby objects of different areas are pushed into the snow pit wall to obtain a relative measure of the hardness of various layers (Colbeck, et al., 1990). Results from the hand hardness test vary between observers, making a comparison matplotlib streamplot animationWebFigure 4. Friction coefficient of bare AISI 301H as a function of the gliding speed on snow at different temperatures: −10 °C (cyan curve, 1); −5 °C (black curve, 2); −3 °C (red curve, 3). For comparison, the µ trend for parallel gliding at −3 °C of stone grinded and waxed UHMWPE (dashed green curve, 4) is shown. matplotlib straight horizontal line
