RISA Model for a Shear-Free Convective Boundary Layer with Parameterized Capping Inversion Structure
Publisher: American Meteorological Society
Abstract: The paper extends Deardorff's general structure parameterization for a shear-free convective boundary layer. The model suggested employs the mixed layer hypothesis that the buoyancy (which is defined as b = g(?0 ? &rho)/?0, ...
Numerical and Laboratory Study of a Horizontally Evolving Convective Boundary Layer. Part I: Transition Regimes and Development of the Mixed Layer
Publisher: American Meteorological Society
Abstract: Results are presented from a large eddy simulation (LES) and wind tunnel study of the turbulence regime in a horizontally evolving sheared atmospheric convective boundary layer (CBL) capped by a temperature inversion. The ...
Numerical and Laboratory Study of Horizontally Evolving Convective Boundary Layer. Part II: Effects of Elevated Wind Shear and Surface Roughness
Publisher: American Meteorological Society
Abstract: Modifications of turbulence regime in the sheared convective boundary layer (CBL) by a number of external nonbuoyant forcings are studied experimentally in a thermally stratified wind tunnel and numerically by means of ...
