Studies of Boundary-Layer Parameters.

Abstract

Theoretical developments are used to show that the ratio of the eddy diffusivity for sensible heat to that for momentum may be equal to one only near adiabatic conditions where coherence and Karmen similarity may be assumed. Measurements made under intermittant or noncoherent conditions are shown to yield fictitious estimates of the eddy diffusivity ratio. The aerodynamic estimates of latent heat flux density and surface stress are compared to independent estimates using shear-stress and evaportranspiration lysimeters and an assumption about the variation of the eddy diffusivity ratios. The influence of the diurnal heating cycle on the diurnal geostrophic wind oscillations is developed and compared to observations. (Author)
