Halogens and their role in polar boundary-layer ozone depletion
Halogens polar boundary-layer ozone depletion
2008/12/17
During springtime in the polar regions, unique photochemistry converts inert halide salt ions (e.g. Br−) into reactive halogen species (e.g. Br atoms and BrO) that deplete ozone in the boundary ...
Boundary-Layer Model Results for Wind-Sea Growth
Boundary-Layer Model Wind-Sea Growth gravity surface wave
2008/12/17
A numerical model of the boundary layer of the atmosphere above a gravity surface wave is reviewed. The model results are used to obtain an expression for the wind input, the wave growth due to the wi...
A Coupled Hydrodynamic–Bottom Boundary Layer Model of Ekman Flow on Stratified Continental Shelves
Hydrodynamic–Bottom Boundary Layer Model Ekman Flow Stratified Continental Shelves
2008/12/16
This paper describes a hydrodynamic model with turbulent energy closure that uses a simplified wave-current interaction model of the bottom boundary layer to compute bed drag coefficients. The coupled...

wave boundary layer small-scale ocean-atmosphere dynamical interactions momentum flux
2008/12/12
An overview of the theory and parameterization of the wave boundary layer (WBL), which is central to small-scale ocean-atmosphere dynamical interactions, is presented. Surface boundary conditions and ...
A Coupled Hydrodynamic–Bottom Boundary Layer Model of Storm and Tidal Flow in the Middle Atlantic Bight of North America
Middle Atlantic Bight Hydrodynamic–Bottom Boundary Layer Model Tidal Flow
2008/12/11
The effects of increased friction and tides on circulation in the Middle Atlantic Bight (MAB) during the SWADE storm of 25–28 October 1990 have been investigated using a three-dimensional hydrodynamic...
Inertial Boundary Layer with a Velocity Front：HOW the Bottom Slope Controls the Western Boundary Current Path
Inertial Boundary Layer Velocity Front Bottom Slope Western Boundary Current Path
2008/12/11
The western boundary current of the subtropical gyre flows on the upper continental slope and is controlled by the bottom topography; however, our theoretical understanding of how the path of the boun...
Deep-Water Upwelling in the Frictional Western Boundary Layer
Deep-Water Upwelling Frictional Western Boundary Layer
2008/12/10
The structure of a Stommel type of frictional western boundary layer in a thermally driven two-layer model is examined. Instead of specifying the interfacial upwelling a priori, it is calculated as pa...
Pressure Compensation and the Bottom Boundary Layer
Pressure Compensation Bottom Boundary Layer
2008/12/10
It is an observed characteristic of oceans that velocities and horizontal pressure gradients are larger new the ocean surface than they are in deeper water. This is conventionally labeled “pressure co...
Boundary layer concentrations and landscape scale emissions of volatile organic compounds in early spring
boundary layer landscape scale emissions volatile organic compounds
2008/12/5
Boundary layer concentrations of several volatile organic compounds (VOC) were measured during two campaigns in springs of 2003 and 2006. The measurements were conducted over boreal landscapes near SM...
