The performance of commonly used subgrid-scale (SGS) models is evaluated for large-eddy simulation (LES) of turbulent katabatic flow. The very stable stratification and strong low-level shear in this flow provide a stringent test for SGS models. Using an a posteriori testing procedure, the SGS models’ performance in reproducing turbulence statistics and spectra in katabatic flow is investigated.
