Abstract: Nonlinear geostrophic adjustment to a mass imbalance is investigated analytically, focusing on horizontal displacement of the equilibrium velocity jet. For no initially imposed horizontal length scale, the jet displacement ...

Abstract: The structure and heat budget of a plume created by a linear heat source is investigated, demonstrating their dependence upon the larger-scale cross-source flow. A large-eddy model simulates individual thermal eddies ...

Abstract: Quasi-lineal ?roll? coherent structures appear in a large eddy simulation of strong wind shear and moderate surface buoyancy flux. Unlike idealized two-dimensional roll vortices, these rolls are finite in length and vary ...

Abstract: Large eddy simulation of a marine boundary layer (BL) with strong wind shear and weak buoyancy flux, over a relatively large horizontal domain (25?18 km) and long time period (16 h), produces lineal eddy structures with ...

Abstract: The ability of an idealized mixed-layer model to predict mesoscale variations in boundary-layer (BL) properties is tested by simulating a case-study day in the Los Angeles Basin, a day typical of their summertime fair ...

Abstract: Mesoscale variation of the boundary-layer (BL) front produced by a surface temperature interface depends upon the scale of meander along that interface. For a relatively large-scale meander, the circulations are quasi ...

Abstract: Turbulence in a ?-mesoscale internal boundary layer (IBL) formed by a discontinuous change in surface roughness has been investigated using a large eddy simulation (LES) model to explicitly treat turbulent transport. Two ...

Abstract: Flow structures in an inhomogeneous neutrally stratified atmospheric boundary layer flow, obtained from large eddy simulation, are analyzed and compared with homogeneous case counterparts. The inhomogeneity is imposed in ...

Abstract: We employ daytime radiosonde data to analyze boundary layer (BL) variability within the Los Angeles Basin for a case study day. The predominantly mesoscale forcing in the region produces large spatial and temporal variations ...
