RISSecond-Moment Budgets and Mixing Intensity in the Stably Stratified Atmospheric Boundary Layer over Thermally Heterogeneous Surfaces
Publisher: American Meteorological Society
Abstract: he effect of horizontal temperature heterogeneity of the underlying surface on the turbulence structure and mixing intensity in the stably stratified boundary layer (SBL) is analyzed using large-eddy simulation (LES). ...
Convective Entrainment into a Shear-Free, Linearly Stratified Atmosphere: Bulk Models Reevaluated through Large Eddy Simulations
Publisher: American Meteorological Society
Abstract: Relationships between parameters of convective entrainment into a shear-free, linearly stratified atmosphere predicted by the zero-order jump and general-structure bulk models of entrainment are reexamined using data from ...
Turbulent Winds and Temperature Fronts in Large-Eddy Simulations of the Stable Atmospheric Boundary Layer
Publisher: American Meteorological Society
Abstract: he nighttime high-latitude stably stratified atmospheric boundary layer (SBL) is computationally simulated using high?Reynolds number large-eddy simulation on meshes varying from 2003 to 10243 over 9 physical hours for ...
