Using structure functions to determine dissipation rates for the stable boundary layer

The determination of turbulent kinetic energy (TKE) dissipation rate according to others characteristics of the flow is an important aspect to numerical meteorological models of distinct temporal and spatial scales. In this work dissipation rates values for different turbulent intensities and heights are obtained for the stable boundary layer using data from the FLOSS experiment. We use the Kolmogorov's Power Law for the second order structure function in the inertial sub-range to determine the dissipation rates. The obtained values of dissipation rate were related to others parameters that describe the turbulent flow (e. g. friction velocity scale, vertical speed standard deviation, Monin-Obukov length) in order to derive empirical relationships for the TKE dissipation rates in terms of these parameters.
