Hore frost is also called "raditionan frost" and it is composed of tiny white crystals.
Some anonymous guy wrote this about hore frost on Wikipedia, that there are four kinds of hore's:
- air hoar - a deposit of hoar frost on objects above the surface, such as tree branches, plant stems, wires;
- surface hoar - formed by fernlike ice crystals directly deposited on snow, ice or already frozen surfaces;
- crevasse hoar - consists in crystals that form in glacial crevasses where water vapour can accumulate under calm weather conditions;
- depth hoar - refers to cup shaped, faceted crystals formed within dry snow, beneath the surface.
