Abstract
Turbulence data from two sites have been analyzed to obtain an indirect relation between the Obukhov stability parameter, z/L, and temperature statistics during dry unstable conditions. The skewness of a single scalar variable, temperature, at a single height is used to obtain z/L, thereby demonstrating the value and importance of the no-Gaussian properties of the temperature statistics.
A relation between σθ/T* and z/L has been obtained for the stability range −60< z/L≤0.5 Explicit forms for heat flux and shear stress have been obtained for the unstable portion of this range in terms of z/L,k, σθ, z, θ and constants. Combining the above techniques provides a method of obtaining z/L, H/pcp and u* from temperature statistics during dry unstable conditions. Within the limitations of the observational uncertainties, the functions appear to be consistent for one or more different sites.
