A turbulent mixture theory for the atmospheric mixture of snow and air.

A theory based on classical fluid mechanics for an incompressible, chemically non-reacting, atmospheric mixuture of air and entrained snow particles is derived. These continuum equations of motion are then expanded to include turbulent flow. The reduced, one-dimensional equations of this theory are further refined by order-of-magnitude analysis and correlation of the turbulent terms to mean flow parameters. -from Authors
