Microphysics of Clouds and Precipitation
Rimed ice crystals and graupel are formed in clouds which contain both ice
crystals and supercooled drops. Field studies have shown that in such clouds
both snow crystals and frozen drops may serve as embryos for graupel formation.
Thus ...

When the ice particle accumulates a heavy coating of rime, it is called graupel.

For example, Schoenberg-Ferrier's model uses very low-density snow, medium-

hail.
