Effects of Double Diffusion and Turbulence on Interleaving at Baroclinic Oceanic Fronts
Publisher: American Meteorological Society
Abstract: Treating the problem of interleaving in ocean fronts, a linear stability analysis is applied to a thermohaline, baroclinic front in which the vertical diffusivity for mass and momentum is determined by both the double ...
Can Turbulence Suppress Double-Diffusively Driven Interleaving Completely?
Publisher: American Meteorological Society
Abstract: A linear stability problem is formulated to investigate the effect of turbulence on double-diffusively driven thermohaline interleaving in rotating media. Three cases are considered: (a) intrusions with an alongfront slope ...
Study of Spatial Spectra of Horizontal Turbulence in the Ocean Using Drifter Data
Publisher: American Meteorological Society
Abstract: The statistics of a pair of Lagrangian particles offer, in principle, a possibility to estimate the structure functions of velocity, then the spatial autocorrelations, and finally the spatial spectra. On the basis of this ...
Effects of Turbulent Mixing and Horizontal Shear on Double-Diffusive Interleaving in the Central and Western Equatorial Pacific
Publisher: American Meteorological Society
Abstract: The effects of small-scale turbulence and the horizontal shear on double-diffusive interleaving are treated in the framework of a linear stability problem in the equatorial ?-plane approximation. The model predicts the ...
The Structure and Driving Mechanisms of the Baltic Intrusions
Publisher: American Meteorological Society
Abstract: Data from closely spaced CTD profiling performed in the eastern Gotland Basin after the 1993 inflow event are used to study thermohaline intrusions in the Baltic Sea. Two CTD cross sections display abundant intrusive layers ...
Eddy Diffusivity Estimates from Lagrangian Trajectories Simulated with Ocean Models and Surface Drifter Data—A Case Study for the Greater Agulhas System
Publisher: American Meteorological Society
Abstract: AbstractThe Lagrangian analysis of sets of particles advected with the flow fields of ocean models is used to study connectivity, that is, exchange pathways, time scales, and volume transports, between distinct oceanic ...
