Graupel differs from hail principally in

  • C.containing no frozen droplets at all
  • D.falling more slowly than a snowflake

Graupel is soft rimed ice a few millimetres across, whereas hail is dense and can be much larger. The distinction is conventional but reflects genuinely different growth conditions. Graupel forms in modest updraughts and hail in violent ones.
