RISScaling Surface Mixing/Mixed Layer Depth under Stabilizing Buoyancy Flux
Publisher: American Meteorological Society
Abstract: his study concerns the combined effects of Earth?s rotation and stabilizing surface buoyancy flux upon the wind-induced turbulent mixing in the surface layer. Two different length scales, the Garwood scale and Zilitinkevich ...
Estimating the Eddy Viscosity Profile from Velocity Spirals in the Ekman Boundary Layer
Publisher: American Meteorological Society
Abstract: urbulent mixing induced by tidal currents near the sea bottom plays a key role in coastal and shallow sea environments. Many attempts have been made to quantify turbulent mixing near the seabed, such as velocity microstructure ...
Mixed Layer Depth and Sea Surface Warming under Diurnally Cycling Surface Heat Flux in the Heating Season
Publisher: American Meteorological Society
Abstract: AbstractIn the present study, large-eddy simulations (LESs) were performed to investigate mixed layer depth (MLD) and sea surface warming (SSW) under diurnally cycling surface heat flux in the heating season, in which a ...
Mutual Interaction between Surface Waves and Langmuir Circulations Observed in Wave-Resolving Numerical Simulations
Publisher: American Meteorological Society
Abstract: Wave-resolving simulations of monochromatic surface waves and Langmuir circulations (LCs) under an idealized condition are performed to investigate the dynamics of wave–current mutual interaction. When the Froude number ...
Reply to “Comments on ‘A Wave-Resolving Simulation of Langmuir Circulations with a Nonhydrostatic Free-Surface Model: Comparison with Craik–Leibovich Theory and an Alternative Eulerian View of the Driving Mechanism’”
Publisher: American Meteorological Society
Abstract: AbstractFujiwara et al. explicitly simulated Langmuir circulations using a wave-resolving simulation (WRS) technique and found that the residual wave effect on vorticity was well represented by the vortex force of the ...
Formation and Circulation Processes of Intermediate Water in the Japan Sea
Publisher: American Meteorological Society
Abstract: The formation and circulation processes of intermediate water in the Japan Sea have been investigated by study of the subduction of mixed layer water. To simulate realistic seasonal variations in the velocity and hydrographic ...
A Wave-Resolving Simulation of Langmuir Circulations with a Nonhydrostatic Free-Surface Model: Comparison with Craik–Leibovich Theory and an Alternative Eulerian View of the Driving Mechanism
Publisher: American Meteorological Society
Abstract: AbstractThe present study performs a wave-resolving simulation of wind-driven currents under monochromatic surface gravity waves using the latest nonhydrostatic free-surface numerical model. Here, phase speed of the waves ...
The Subpolar Front of the Japan/East Sea. Part II: Inverse Method for Determining the Frontal Vertical Circulation
Publisher: American Meteorological Society
Abstract: An inverse method for inferring vertical velocities from high-resolution hydrographic/velocity surveys is formulated and applied to observations collected at the subpolar front of the Japan/East Sea (JES) taken during ...
The Subpolar Front of the Japan/East Sea. Part III: Competing Roles of Frontal Dynamics and Atmospheric Forcing in Driving Ageostrophic Vertical Circulation and Subduction
Publisher: American Meteorological Society
Abstract: he effects of wind stress and surface cooling on ageostrophic vertical circulation and subduction at the subpolar front of the Japan/East Sea are investigated using a nonhydrostatic numerical model. In experiments forced ...
