| 説明 | Hailstone damage - broken window on 2nd floor of west-facing side of a motel in Limon, Colorado, USA (morning following a 4 July 2010 hailstorm).Hailstones are scarce, ephemeral, polycrystalline, concentrically layered, monomineralic rocks of meteoric origin. They are composed of the mineral ice (hydrogen oxide, H2O). Ice has a low melting temperature for a mineral (= 0˚ Celsius/Centrigrade; = 32˚ Fahrenheit; = 273˚ Kelvin). As a result of this, rocks (hailstones, firn, glacial ice) and sedimentary deposits (snow) consisting of ice are ephemeral, except at very high elevations (mountain tops) and in polar to near-polar facies. Hailstones form in many thunderstorms and can reach the land surface before melting. They range in size from about half-a-centimeter to over 20 centimeters (very large hailstones such as: www.flickr.com/photos/75478688@N08/6804952627/in/photostr... and www.flickr.com/photos/74109683@N03/6807753397/in/photostr... are not really hailstones, but are aggregate hailstones, formed by ice cementing many smaller hailstones together). Hailstones form spherical to subspherical to irregularly-shaped masses.The term "cryometeorites" has been applied to hailstones by some people. Considering that they have a meteoric origin, and do not originate from outer space, this term is inappropriate and is rejected here.The most significant hailstone occurrence & hailstone damage I've ever seen was at Limon, Colorado, USA on the evening of 4 July 2010 and the following morning. A relatively small, but intense, storm cell went over the small town of Limon on America's Indepedence Day, resulting in the deposition of a moderately thick layer of small-to-large hailstones in surface depressions.
