Observations, Experiments, and Large Eddy Simulation [PDF]
Bulletin of the American Meteorological Society, 2001 Abstract The authors use a 1998 workshop titled "Observations, Experiments, and Large–Eddy Simulation" as a springboard to begin a dialogue on the philosophy of simulation as well as to examine the relationship of large eddy simulation (LES) of geophysical flows to both observations and experiments.

An Embedded Boundary Algorithm for Large Eddy Simulations in Complex Geometries [PDF]
INCAS Bulletin, 2012 The paper presents a novel implementation of the embedded boundary algorithm in a Large Eddy Simulation CFD algorithm. The embedded boundary method aims at allowing the simulation of complex geometry flows on Cartesian computational grids, increasing the

Statistical ensemble of large-eddy simulations [PDF]
Journal of Fluid Mechanics, 2002 A statistical ensemble of large-eddy simulations (LES) is run simultaneously for the same flow. The information provided by the different large-scale velocity fields is used in an ensemble-averaged version of the dynamic model. This produces local model parameters that only depend on the statistical properties of the flow.

Evaluation of a Buoyancy and Shear Based Mixing Length for a Turbulence Scheme
Frontiers in Earth Science, 2017 We present a new diagnostic mixing length for a turbulence scheme based on a prognostic equation for the turbulence kinetic energy. The formulation adds a local vertical wind shear term to the non-local buoyancy-based mixing length currently used in the ...

Vertical transport of pollutants by shallow cumuli from large eddy simulations [PDF]
Atmospheric Chemistry and Physics, 2012 This study investigates the vertical transport of a passive tracer in a shallow cumulus boundary layer using large eddy simulations. The tracer source is at the surface in one case, and in the inversion layer in the other case.
