Description: Research Report
Summary: The relative rates of melting and evaporation of a snow cover under meteorological conditions favoring evaporation are discussed. Snow-surface evaporation occurs only with a snow-to-air vapor pressure gradient and is proportional to the gradient, other things being equal. Appreciable evaporation occurs only when there is turbulent transfer of heat from the air to the snow. Little evaporation occurs without simultaneous melting at a higher rate. A graph is presented for predicting evaporation or condensation over a snow cover when temperature and relative humidity of the air, and snow-surface temperature are known.
