В словнику:
soft hail, graupel, snow pellets - снігові́ крупці

However, snow/ice pellets are distinct from soft hail, graupel:
"Ice pellets are smaller than hailstones[1] which form in thunderstorms rather than in winter, and are different from graupel ("soft hail") which is made of frosty white rime, and from a mixture of rain and snow which is a slushy liquid or semisolid." ---

Але межа не дуже чітка, та ж вікіпедія каже

Graupel (German pronunciation: [ˈɡʁaʊpəl]; English /ˈɡraʊpəl/), also called soft hail or snow pellets

і я не впевнений, що у нас є чіткі різні терміни для цих понять
