It was a cold showery day today. There was a fair bit of graupel in the snowpack and falling out the sky.Â Graupel is small ball bearing like pieces of ice which are formed by the riming up of snowflakes as they fall. It is like hail, but not quite as hard or dense, it is sometimes known as soft hail (see picture below). There is very little cohesion between the grains, and as you can imagine incorporating a layer of ball-bearing like particles into the snowpack does not improve stability. It is also rather “exfoliating” on the face on a windy day (like yesterday).
