This phenomenon is described by the code GR in the METAR system. The magnitude of this phenomenon can be predicted with Vertical Integrated Liquid Density, which measures both the moisture content of a cloud and the strength of its updrafts. This phenomenon is caused when (*) water droplets are blown upward, where cold air freezes them, before falling to the ground. For 10 points, name this type of precipitation consisting of balls of ice.
