| From the base local showers of rain or snow, occasionally of hail or graupel, usually fall. |
| When the riming is substantial enough, the crystal form of the snowflake is lost and replaced by a more or less spherical particle called graupel. |
| Frozen forms of precipitation include snow, ice needles, ice pellets, hail, and graupel. |
| The amount and polarity of the graupel charges depend on the ambient air temperature and on the liquid water content of the cloud, as well as on the ice crystal size, the velocity of the collision, and other factors. |
| 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. |
