Abstract: Graupel is a common and, normally, short lived weak layer in maritime snow climates. Graupel forms during storms from strong convective activity and can be caused by the passage of a cold front or during springtime convective shower activity. Graupel looks like a pile of ball bearings and is heavily rimed new snow. Most literature and research within North America, including educational material from the American Avalanche Association and Avalanche Canada, points to graupel being a non-persistent weak layer that should stabilize quickly. Can graupel layers persist for longer periods of time than previously thought?
