Abstract: he interactions surrounding the coupling between surface energy balance and a boundary layer with shallow cumuli are investigated using the National Center for Atmospheric Research?s large-eddy simulation code coupled to ...

Abstract: AbstractA novel approach is constructed for determining both the occurrence and the duration of stationary periods within time series. After reviewing four statistical techniques that provide stationarity measures invariant ...

Abstract: massively parallel large-eddy simulation (LES) code for planetary boundary layers (PBLs) that utilizes pseudospectral differencing in horizontal planes and solves an elliptic pressure equation is described. As an application, ...

Abstract: his study demonstrates that a pulsed wind lidar is a reliable instrument for measuring angles between horizontal vectors of significance in the atmospheric boundary layer. Three different angles are considered: the wind ...

Abstract: omentum and scalar transport in the marine atmospheric boundary layer (MABL) is driven by a turbulent mix of winds, buoyancy, and surface gravity waves. To investigate the interaction between these processes, a large-eddy ...

Abstract: This manuscript describes numerical experiments investigating the influence of 2?30-km striplike heterogeneity on wet and dry convective boundary layers coupled to the land surface. The striplike heterogeneity is shown to ...

Abstract: AbstractA combination of turbulence-resolving large-eddy simulations and observations are used to examine the influence of swell amplitude and swell propagation angle on surface drag. Based on the analysis a new surface ...

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 ...
