The Influence of Boundary Layer Dynamics and Thermodynamics on the Diagnosis of Near-Surface Wind Speed by Synthetic Aperture Radar

Abstract

Procedures have been developed which employ Monin-Obukhov and mixed layer similarity theory to produce Obukhov length (L), convective velocity scale, buoyancy flux, and a stability corrected wind speed from SAR-derived neutral wind imagery (Young and Sikora, submitted to Monthly Weather Review, 1998). These procedures are based on the variance and spectral shape of the neutral wind imagery. It is hypothesized that there is a static stability/ mean wind speed limit in the usefulness of these techniques. The long term goals of the current research are to thoroughly test and document the usefulness of the above-mentioned SAR-MABL techniques under varying degrees of Bulk Richardson Number (Rb) in order to quantify and account for these potential problems.
