Query: Large-Eddy Simulation of Stably Stratified Atmospheric Boundary Layer
  Turbulence: A Scale-Dependent Dynamic Modeling Approach   A new tuning-free subgrid-scale model, termed `locally-averaged
scale-dependent dynamic' (LASDD) model, is developed and implemented in
large-eddy simulations (LESs) of stable boundary layers. The new model
dynamically computes the Smagorinsky coefficient and the subgrid-scale Prandtl
number based on the local dynamics of the resolved velocity and temperature
fields. Overall, the agreement between the statistics of the LES-generated
turbulence and some well-established empirical formulations and theoretical
predictions (e.g., Nieuwstadt's local scaling hypothesis) is remarkable. The
results show clear improvements over most of the traditional subgrid-scale
models in the surface layer. Moreover, in contrast to previous large-eddy
simulations of stable boundary layers that have strong dependence on grid
resolution, the simulated statistics obtained with the LASDD model show
relatively little resolution dependence for the range of grid sizes considered
here. In essence, we show that the new LASDD model is a robust subgrid-scale
parameterization for reliable, tuning-free simulations of stable boundary
layers, even with relatively coarse resolutions.
