Abstract: Large-eddy simulations of a free convective atmospheric boundary layer with an overlying capping inversion are considered. Attention is given to the dependence of the results upon the various factors influencing the ...

Abstract: In a recent paper, Kuo and Schubert demonstrated the lack of observational support for the relevance of the criterion for cloud-top entrainment instability proposed by Randall and by Deardorff. Here we derive a new criterion, ...

Abstract: A new instrument package has been developed to measure turbulence at various heights in the boundary layer. The package or ?turbulence probe? is designed to be attached to the tethering cable of a balloon. In contrast to ...

Abstract: Previous experiments on thermal convection in a rotating fluid annulus (of depth d, inner radius a and outer radius b subject to an impressed horizontal temperature contrast ?T have been extended to very small values of ...

Abstract: Large eddy simulations use a subgrid model, which is characterized by a length scale that is often related to the scale of the computational mesh by a numerical constant, Cs. Mason and Callen argued that this subgrid model ...

Abstract: Large eddy simulations sometimes use monotone advection schemes. Such schemes are dissipative, and the effective subgrid model then becomes the combined effect of the intended model and of the numerical dissipation. The ...

Abstract: Detailed studies of the azimuthal structure of fully developed waves in a differentially heated rotating fluid annulus have been carried out with the aid of instrumentation capable of providing frequent determinations of ...
