| 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. AMSglossary
