    "abstract": "A new scale-dependent dynamic subgrid-scale (SGS) model based on Kolmogorov\u0027s\nscaling hypothesis is presented. This SGS model is utilized in large-eddy\nsimulation of a well-known case study on shear-driven neutral atmospheric\nboundary layer flows. The results are compared comprehensively with an\nalternate scale-dependent dynamic SGS model based on the popular Smagorinsky\nclosure. Our results show that, in the context of this particular problem, the\nscale-dependent dynamic modeling approach is extremely useful, and reproduces\nseveral establised results (e.g., the surface layer similarity theory) with\nfidelity. Results from both the SGS base models are generally in close\nagreement, although we find a consistent superiority of the Smagorinsky-based\nSGS model for predicting the inertial range scaling of spectra.",
