RISMixing Nonlocality and Mixing Anisotropy in an Idealized Western Boundary Current Jet
Publisher: American Meteorological Society
Abstract: AbstractMotivated by the key role of western boundary currents in shaping water mass distribution and gyre water exchanges, this study characterizes mixing in an idealized western boundary current jet using a barotropic ...
Eddy-Driven Recirculations from a Localized Transient Forcing
Publisher: American Meteorological Society
Abstract: he generation of time-mean recirculation gyres from the nonlinear rectification of an oscillatory, spatially localized vorticity forcing is examined analytically and numerically. Insights into the rectification mechanism ...
Eddy Shape, Orientation, Propagation, and Mean Flow Feedback in Western Boundary Current Jets
Publisher: American Meteorological Society
Abstract: his manuscript revisits a study of eddy?mean flow interactions in an idealized model of a western boundary current extension jet using properties of the horizontal velocity correlation tensor to diagnose characteristics ...
Geometric Decomposition of Eddy Feedbacks in Barotropic Systems
Publisher: American Meteorological Society
Abstract: n oceanic and atmospheric flows, the eddy vorticity flux divergence?denoted ?F? herein?emerges as a key dynamical quantity, capturing the average effect of fluctuations on the time-mean circulation. For a barotropic system, ...
Turbulence and Mixing in the Arctic Ocean’s Amundsen Gulf
Publisher: American Meteorological Society
Abstract: This study uses CTD and microstructure measurements of shear and temperature from 348 glider profiles to characterize turbulence and turbulent mixing in the southeastern Beaufort Sea, where turbulence observations are ...
On Using the Finescale Parameterization and Thorpe Scales to Estimate Turbulence from Glider Data
Publisher: American Meteorological Society
Internal Waves and Turbulence in the Antarctic Circumpolar Current
Publisher: American Meteorological Society
Abstract: his study reports on observations of turbulent dissipation and internal wave-scale flow properties in a standing meander of the Antarctic Circumpolar Current (ACC) north of the Kerguelen Plateau. The authors characterize ...
Jet–Topography Interactions Affect Energy Pathways to the Deep Southern Ocean
Publisher: American Meteorological Society
Abstract: AbstractIn the Southern Ocean, strong eastward ocean jets interact with large topographic features, generating eddies that feed back onto the mean flow. Deep-reaching eddies interact with topography, where turbulent ...
Eddy–Mean Flow Interaction in the Kuroshio Extension Region
Publisher: American Meteorological Society
Abstract: he authors use data collected by a line of tall current meter moorings deployed across the axis of the Kuroshio Extension (KE) jet at the location of maximum time-mean eddy kinetic energy to characterize the mean jet ...
Eddy-Induced Modulation of Turbulent Dissipation over Rough Topography in the Southern Ocean
Publisher: American Meteorological Society
Abstract: esoscale eddies are universal features of the ocean circulation, yet the processes by which their energy is dissipated remain poorly understood. One hypothesis argues that the interaction of strong geostrophic flows with ...
