*Hail* is a form of solid precipitation. It consists of balls or irregular
lumps of ice, each of which is called a *hailstone*.^[1] Unlike graupel,
which is made of rime, and ice pellets, which are smaller and translucent,
hailstones – on Earth – consist mostly of water ice and measure
between 5 millimetres (0.20 in) and 15 centimetres (6 in) in diameter.
The METAR reporting code for hail 5 mm (0.20 in) or greater is *GR*,
while smaller hailstones and graupel are coded *GS*. Hail is possible
within most thunderstorms as it is produced by cumulonimbi,^[2] and within
2 nautical miles (3.7 km) of the parent storm. Hail formation requires
environments of strong, upward motion of air with the parent thunderstorm
(similar to tornadoes) and lowered heights of the freezing level. In the
mid-latitudes, hail forms near the interiors of continents, while in the
tropics, it tends to be confined to
