What Is Rime?
A white, crusty ice coating that forms when tiny supercooled fog or cloud droplets freeze on contact with objects. In technical terms: A granular, opaque ice deposit formed by rapid freezing of supercooled droplets on impact with a surface, trapping air; forms at temperatures typically below -5 °C; heavy riming of snowflakes forms graupel.
