Hail
Hail is a form of solid precipitation. It consists of balls or irregular lumps of ice, each of which is referred to as a hail stone. Unlike graupel, which is made of rime, and ice pellets, which are smaller and translucent, hail stones – on Earth – consist mostly of water ice and measure between 5 and 200 millimetres (0.20 and 7.9 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 (thunderclouds), 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 high elevations.

Famous quotes containing the word hail:
“Out of the slimy mud of words, out of the sleet and hail of verbal imprecisions,
Approximate thoughts and feelings, words that have taken the place of thoughts and feelings,
There springs the perfect order of speech, and the beauty of incantation.”
—T.S. (Thomas Stearns)
“And before, with banner red,
Through the blizzard snow unseen,
All unharmed by hail of lead,
With a step like snow so light,
Showered in myriad pearls of snow.
Crowned in wreath of roses white,
Christ leads onward as they go.”
—Alexander Blok (1880–1921)
“You can’t run the Church on Hail Marys.”
—Paul Marcinkus (b. 1922)
