The objective of this study is to establish a simple wind profile parameterization for the U.S. Army Research Laboratorys ARL diagnostic Three-Dimensional Wind Field 3DWF Model in gentle terrain and vegetation canopies. The Project Wind in Non-uniform Domains WIND data was applied for the analysis of wind profiles in open terrain, forest edge, and the interior of forest. A wind profile parameterization scheme was proposed according to this analysis and additional information found in the literature of other studies. The 3DWF simulation results using this scheme were compared with the observations to establish the confidence level of this parameterization. The analysis and comparison indicated that the 3DWF using this parameterization gives a reasonable accurate wind field prediction in a gentle terrain with vegetation environment. The application of the parameterization for different scenarios of data availability was also discussed.
