Snow eater

From Glossary of Meteorology

snow eater

  1. Any warm wind blowing over a snow surface; usually applied to a foehn wind, that is, schneefresser.

    See also chinook.

  2. A fog over a snow surface; so called because of the frequently observed rapidity with which a snow cover disappears after a fog sets in.

    As water vapor from the air condenses on the snow, the latent heat of condensation causes the snow to become warmer and melt faster.
