The effect of Physical Parameterization in WRF Model for Simulation of Tehran's Wind Field

Simulation of wind field is important for numerical simulating of Atmospheric dispersing models in unsteady conditions. In this case, simulation of Tehran's Wind Field has been considered.. The main goal of this study was considering the physical parameterization effects of WRF model in Tehran's Wind Field simulations. The considered parameters were Cloud Micro-Physics, Planetary Boundary Layer Scheme and Land Surface Scheme. FNL data was used to run WRF model and simulate the Wind Field during whole 2008 year. the results of simulations were compared with Wind observation valuesin the MehrAbad Airport and Doshan-Tappeh Airport stations. All Wind Field simulations were compared to Wind Observation values in five approaches. The Wind Field simulations was obtained by using continues daily mean, daily averaging from Wind Value in UTC(s), continues 3 hourly in UTC Intervals, using exact Wind valuesat UTC(s) and 10 minutes Averaging of Wind Values at UTC(s) methods. The results showed that physical parameterization include MRF scheme, Monin-Obukhov scheme, Noah land-surface model (Chen) and WSM 6-class grapple scheme depends on 256 configurations, were the more suitable parameters configuration on Tehran's Wind Field simulation.
