Abstract
The one-dimensional stochastic Burgers equation has the remarkable ability to mimic some of the fundamental statistical and dynamical properties of three-dimensional fully developed turbulence. In this study, we numerically investigate the competence of commonly used dynamic eddy-viscosity-type subgrid-scales (SGSs) models in large-eddy simulation of this equation. We found that the inertial-range characteristics of Burgers turbulence (also known as Burgulence) are well preserved by this class of SGS models.

Notes
1. These SGS models are widely used by the atmospheric boundary layer turbulence community (see [Citation31] and the references therein).
2. Estimation of C n for n > 3 typically requires extremely large sample size for achieving statistical convergence, and thus is not attempted in the present study.
