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

We have processed more than 50 hours of TODWL data from both the Monterey and DPG areas. We have begun combining the information from the TODWL, CTV and Twin Otter sensors to establish the relationship between the local fluxes and the energetic of LLJs and OLEs. We have also begun to modify the EDMF (Eddy Diffusivity and Mass Flux) parameterization to account for the differences between thermally driven convection and dynamically driven vertical transports. The WRF model has been setup and run for the 7 MATERHORN missions and comparisons between the TODWL wind profiles and the model profiles have been completed for one day. The OLE model has been modified to investigate "stacked OLEs" seen in the April 2007 datasets.
