| These can be grouped into general classes such as dendrites, needles, plates, and graupel. |
| From the base local showers of rain or snow, occasionally of hail or graupel, usually fall. |
| 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. |
| The repeated collision of ice crystals and graupel in clouds is associated with the buildup of electrical charge. |
| Notice for this wind field that graupel falls rapidly to the surface and drifts only a short distance downwind. |
| In this work the growth, motion and charging of graupel particles are simulated by computer. |
