Abstract
Unlike evaporation and condensation that can occur throughout the depth of the atmosphere, the melting of snowflakes can only occur at temperatures near 0°C. The cooling of the atmosphere because of this melting often results in the development of an isothermal layer at 0°C and a region of instability below it. In this paper we consider the effect that the cooling caused by melting of snowflakes has on the resultant convective activity. This cooling results in upward vertical velocities and upward penetration depths that are significantly smaller than those anticipated from consideration of saturated adiabatic processes and particle drag alone.
