Use of 915 MHz wind profiler data to describe the diurnal variability of the mixed layer
Abstract
The physical processes that affect the shape of the C(n)-squared profile in the cloud-free convective PBL using the top-down and bottom-up diffusion scaling approach developed by Wyngaard and Brost (1984) and extended to structure function parameters by Fairall (1987) are discussed. Time series of radar reflectivity data are analyzed to examine the potential applicability of these data for describing the diurnal variability of the turbulent mixed layer, and particularly the height of the capping version. The results suggest the potential utility of using clear-air radar backscatter intensity, when the proper meteorological conditions exist, to infer information about PBL structure and important turbulent processes such as entrainment.
