A Large Eddy Simulation Study of a Quasi-Steady, Stably Stratified Atmospheric Boundary Layer
Publisher: American Meteorological Society
Abstract: Using the large eddy simulation (LES) technique, the authors study a clear-air, stably stratified atmospheric boundary layer (ABL) as it approaches a quasi-steady state. The Beaufort Sea Arctic Stratus Experiment (BASE) ...
Generation of Inflow Turbulence in Large-Eddy Simulations of Nonneutral Atmospheric Boundary Layers with the Cell Perturbation Method
Publisher: American Meteorological Society
Abstract: AbstractRealistic multiscale simulations involve coupling of mesoscale and large-eddy simulation (LES) models, thus requiring efficient generation of turbulence in nested LES domains. Herein, we extend our previous work ...
Source Inversion for Contaminant Plume Dispersion in Urban Environments Using Building-Resolving Simulations
Publisher: American Meteorological Society
Abstract: The ability to determine the source of a contaminant plume in urban environments is crucial for emergency-response applications. Locating the source and determining its strength based on downwind concentration measurements, ...
Resolved Turbulence Characteristics in Large-Eddy Simulations Nested within Mesoscale Simulations Using the Weather Research and Forecasting Model
Publisher: American Meteorological Society
Abstract: ne-way concurrent nesting within the Weather Research and Forecasting Model (WRF) is examined for conducting large-eddy simulations (LES) nested within mesoscale simulations. Wind speed, spectra, and resolved turbulent ...
100 Years of Progress in Applied Meteorology. Part III: Additional Applications
Publisher: American Meteorological Society
Abstract: AbstractApplied meteorology is an important and rapidly growing field. This chapter concludes the three-chapter series of this monograph describing how meteorological information can be used to serve society?s needs while ...
Limitations of One-Dimensional Mesoscale PBL Parameterizations in Reproducing Mountain-Wave Flows
Publisher: American Meteorological Society
Abstract: esoscale models are considered to be the state of the art in modeling mountain-wave flows. Herein, the authors investigate the role and accuracy of planetary boundary layer (PBL) parameterizations in handling the interaction ...

Publisher: American Meteorological Society
Implementation and Evaluation of Dynamic Subfilter-Scale Stress Models for Large-Eddy Simulation Using WRF
Publisher: American Meteorological Society
Abstract: he performance of a range of simple to moderately-complex subfilter-scale (SFS) stress models implemented in the Weather Research and Forecasting (WRF) model is evaluated in large-eddy simulations of neutral atmospheric ...
Transition and Equilibration of Neutral Atmospheric Boundary Layer Flow in One-Way Nested Large-Eddy Simulations Using the Weather Research and Forecasting Model
Publisher: American Meteorological Society
Abstract: he Weather Research and Forecasting Model permits finescale large-eddy simulations (LES) to be nested within coarser simulations, an approach that can generate more accurate turbulence statistics and improve other aspects ...
