Abstract: A running-mean operator is used to average predefined signals in order to calculate subgrid-scale (SGS) contributions. The role of the Leonard and cross terms (l and C, respectively) in the definition of the SGS is studied ...

Abstract: The theoretical analysis presented recently on the role of Leonard and cross terms in determining the subfilter contribution when using a running mean is verified using atmospheric measurements. Measurements of variables ...

Abstract: The nocturnal cycle of nitrogen oxides in the atmospheric boundary layer is studied by means of a one-dimensional model. The model solves the conservation equations of momentum, entropy, total water content, and of five ...
