0 snowflakes covered with ice, or one of these snowflakes:
70% of the rain water came from the melting of graupel and hail.
If the graupel layer was an inch or more, the snow from this storm would likely be avalanche.
A graupel or a frozen raindrop may become the initial stage of a much faster growth.
When this process continues so that the shape of the original snow crystal is no longer identifiable, the resulting crystal is referred to as graupel.
Graupel was formerly referred to by meteorologists as soft hail.
Convectional precipitation, typically thunderstorms, often forms rapidly and frequently drop graupel or hail.
The strongest backscatter comes from hail and large graupel (solid ice) due to their sizes.
Frozen forms of precipitation include snow, ice needles, sleet, hail, and graupel.
