Rime ice

Rime ice a solid form of atmospheric deposition, a certain kind of ice created when supercooled water droplets freeze onto surfaces. In the atmosphere, there are three basic types of rime ice:
Hard rime on a tree
Wind blown rime ice formed on the summit cross of the Fronalpstock
Hard rime on trees in the Black Forest of Germany

Frost is a layer of ice on a solid surface, which forms from water vapor that deposits onto a freezing surface. Frost forms when the air contains more water vapor than it can normally hold at a specif

…types of rime ice: Soft rime forms when supercooled water freezes under calm wind conditions. It is milky and crystalline, like sugar, and similar to hoar frost. Hard rime forms by rapid freezing of supercooled water under at least moderate wind conditions. The droplets freeze more or less individually, leaving…
