Investigation of the Representation of OLEs and Terrain Effects within the Coastal Zone in the EDMF Parameterization Scheme: An Airborne Doppler Wind Lidar Perspective

Abstract

Work continued on the evaluation and development of the Eddy Diffusivity Mass Flux (EDMF) parameterization of turbulence and convective mixing in numerical models. The main focus was in using previously obtained Twin Otter Doppler Wind Lidar (TODWL) data near Monterey, CA and Dugway, UT to investigate the physical characteristics, TKE transports and contributions to EDMF parameterization by boundary layer rolls and near surface "turbulence channels. A triad model was updated and modified to simulate rolls (including stacked rolls) in preparation for modifying current EDMF expressions We also continued to investigate the sensitivity of the WRF and COAMPS model to modified EDMF.
