Simulation of Atmospheric Boundary Layer for Air Inlet Testing in Crossflow

Large-eddy simulation of turbulent flow over an array of wall-mounted cubes submerged in an emulated atmospheric boundary-layer

Turbulent flow over an array of wall-mounted cubic obstacles has been numerically investigated using large-eddy simulation. The simulations have been performed using high-performance computations with local cluster systems. The array of cubes are fully submerged in a simulated deep rough-wall atmospheric boundary-layer with high turbulence intensity characteristics of environmental turbulent fl...

Considerations for bistatic probing of clear-air winds in the atmospheric boundary layer

The Martian Atmospheric Boundary Layer

[1] The planetary boundary layer (PBL) represents the part of the atmosphere that is strongly influenced by the presence of the underlying surface and mediates the key interactions between the atmosphere and the surface. On Mars, this represents the lowest 10 km of the atmosphere during the daytime. This portion of the atmosphere is extremely important, both scientifically and operationally, be...

The Role of Atmospheric Boundary Layer Processes in Atmospheric Chemistry

WHAT: Junior and senior researchers identified, discussed, and studied outstanding issues related to atmospheric boundary layer processes closely linked to atmospheric chemistry WHEN: 20–24 November 2006 WHERE: Castelldefels, Spain he importance of atmospheric boundary layer (ABL) dynamics and physics in controlling key aspects of atmospheric chemistry is becoming increasingly recognized. Proce...

Parameterization of the Atmospheric Boundary Layer A

tion models, in spite of some advances, the boundary layer is still not represented realistically. Figure 1 illustrates an aspect of this problem by showing the opposing response of boundary layer (low) clouds to perturbation experiments (e.g., double CO2) in current climate models. The general problem of parameterization in fluids dates back to the first modern studies of turbulence during the...
