The continuous increase in computational resources is enabling the application of high fidelity turbulence modeling approaches to atmospheric flow simulations. This section is dedicated to a large-eddy simulation study that we performed for Oklahoma City. We considered a unique dominant wind direction. The results are compared to the nominal RANS results and the field experiment data to determine the benefits and challenges of large eddy simulations for these complex flow problems. These comparison can be found in the resources included in the publication section.
