An Analysis of the Wyngaard-LeMone Model of Refractive Index and Micrometeorological Structure Functions at the Top of a Turbulent Mixed Layer.
Abstract
This report is a theoretical and experimental analysis of a model used to calculate the refractive index structure function parameter, C sub n squared, at the interfacial region at the top of an entraining, turbulent mixed layer. C sub n squared is related to the micrometeorological structure functions for temperature, humidity, and T-Q covariance. The mixed layer interfacial region is important for EM propagation because C sub n squared is greatly increased by large T and Q fluctuations due to the entrainment of warm, dry air from the nonturbulent atmosphere above the mixed layer. The theoretical basis of this model is examined and four data sets from the NPS aircraft measurements program are used to test the model.
