White frost

Alternative definitions (1), class: vernacular (0)
Term: White frost
Definition: 1. A relatively heavy coating of hoarfrost. With respect to vegetation, a white frost is less damaging than a black frost for at least two reasons: 1) it tends to insulate the plant from further cold; and 2) it releases latent heat of fusion (albeit slight) to the environment. 2. Colloquial term for a deposit of fine rime.
