Hierarchy of Mesoscale Flow Assumptions and Equations
Publisher: American Meteorological Society
Abstract: The present research proposes a standard nomenclature for mesoscale meteorological concepts and integrates existing concepts of atmospheric space scales, flow assumptions, governing equations, and resulting motions into a ...
Formulation and Evaluation of a Nonhydrostatic Mesoscale Vorticity Model (TVM)
Publisher: American Meteorological Society
Abstract: This paper describes the formulation and the application of the nonhydrostatic anelastic vorticity model (TVM). This model is constructed using a method involving two horizontal streamfunctions and two horizontal vorticity ...
On the Validity of Reynolds Assumptions for Running-Mean Filters in the Absence of a Spectral Gap
Publisher: American Meteorological Society
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 ...
Estimating the Contribution of Leonard and Cross Terms to the Subfilter Scale from Atmospheric Measurements
Publisher: American Meteorological Society
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 ...
Topographic Vorticity-Mode Mesoscale-β (TVM) Model. Part I: Formulation
Publisher: American Meteorological Society
Abstract: The three-dimensional, flat-terrain, finite-difference URBMET vorticity, mode mesoscale-? model has been modified to include topographic effects. The resulting topographic vorticity-mode mesoscale-? (TVM) model is hydrostatic, ...
Topographic Vorticity-Mode Mesoscale-β (TVM) Model. Part II: Evaluation
Publisher: American Meteorological Society
Abstract: The new topographic vorticity-mode mesoscale-? (TVM) model, whose formulation is described in Part I of this paper, was used to simulate data from the June 1983 Sixth European Remote Sensing Campaign on Air Pollution at ...
