What is the characteristic of rime icing?

Rime icing is characterized by its formation process where supercooled water droplets freeze on impact with a surface, resulting in a creamy and rough appearance. This type of icing typically occurs under conditions where there is a significant amount of moisture in the air combined with cold temperatures, leading to the rapid freezing of the droplets as they come into contact with colder surfaces.

When considering the other aspects of rime icing, it does not classify as soft and slippery; rather, its texture is rough due to the nature of the freezing process. Additionally, while rime icing can develop in freezing rain, it is specifically tied to the impact of supercooled droplets rather than the steady accumulation typically associated with such rain. Lastly, rime icing does not have a strict temperature threshold for its formation, as it can occur at various temperatures, depending on the specific atmospheric conditions, rather than being limited to below -10°C.
