Note on the vertical velocity and diffusive salt flux induced by evaporation and precipitation

Some (not all) of the oceanographic literature slightly miscalculates the vertical velocity (w) and diffusive salt flux induced by evaporation (E) and precipitation (P) at the sea surface. Short, simple, physical derivations are presented to show that, for a sea surface h = h(x, y, t) varying in space and time, 1) w = VH · h + ∂h/∂t + ρF(E − P)/ρ, where VH is the horizontal component of the aggregate parcel velocity, and ρF and ρ are the densities of freshwater and surface seawater, respectively; and 2) the vertical diffusive salt flux at the sea surface (whether molecular or turbulent) is −ρFS(E − P), where S is the surface salinity.

On sea surface salinity skin effect iInduced by evaporation and implications for remote sensing of ocean salinity Yu, Lisan (American Meteorological Society, 2010-01)The existence of a cool and salty sea surface skin under evaporation was first proposed by Saunders in 1967, but few efforts have since been made to perceive the salt component of the skin layer. With two salinity missions ...
Menezes, Viviane V.; Farrar, J. Thomas; Bower, Amy S. (Elsevier, 2018-03-19)We analyse ten years of QuikSCAT satellite surface winds to statistically characterize the spatio-temporal variability of the westward mountain-gap wind jets over the northern Red Sea. These wind jets bring relatively cold ...
