Abstract:

Expressions for the ratio of the turbulent Schmidt (Sct) to Prandtl (Prt) numbers are derived for an idealized atmospheric surface layer flow over water surfaces. Conditions where the ansatz Sct/Prt1are then discussed. It is shown that Sct/Prt1 is consistent with the active role of temperature in turbulence generation or destruction even when perfect similarity between turbulent transport of heat and water vapor is absent.
