Form of the Temperature-Salinity Relationship in the Central Water: Evidence for Double-Diffusive Mixing
Publisher: American Meteorological Society
Abstract: Ingham (1966) reported that the temperature-salinity relationships in the Central Waters were much better described by a curve of constant density ratio (R? = α?T/??S) than by a straight line. His result is quantitatively ...
The Salt Finger Experiments of Jevons (1857) and Rayleigh (1880)
Publisher: American Meteorological Society
Abstract: Over a century before Melvin Stern discovered salt fingers, W. Stanley Jevons performed the first salt finger experiment in an attempt to model cirrus clouds. Remarkably, he seemed to realize that a more rapid diffusion ...
On the Density Ratio Balance in the Central Water
Publisher: American Meteorological Society
Abstract: An equation for the conservation of density ratio on isopycnal surfaces is derived. It is shown that a vertical shear can modify the density ratio if salinity (and temperature) gradients exist along isopycnals. The mixing ...
The Impact of Salt Fingering on the Thermohaline Circulation under Mixed Boundary Conditions
Publisher: American Meteorological Society
Abstract: The impact of salt fingers on the thermohaline circulation in a single hemisphere basin under mixed boundary conditions is investigated through scaling analysis and numerical experiments. By assuming that the internal ...
Estimates of Cabbeling in the Global Ocean
Publisher: American Meteorological Society
Abstract: wing to the larger thermal expansion coefficient at higher temperatures, more buoyancy is put into the ocean by heating than is removed by cooling at low temperatures. The authors show that, even with globally balanced ...
The Contribution of Salt Fingers to Vertical Mixing in the North Atlantic Tracer Release Experiment
Publisher: American Meteorological Society
Abstract: The North Atlantic Tracer Release Experiment (NATRE) was performed in an area moderately favorable to salt fingers. However, the classic finger signature of a distinct thermohaline staircase caused by upgradient density ...
Centennial Changes of the Global Water Cycle in CMIP5 Models
Publisher: American Meteorological Society
Abstract: he global water cycle is predicted to intensify under various greenhouse gas emissions scenarios. Here the nature and strength of the expected changes for the ocean in the coming century are assessed by examining the output ...
Fine and Microstructure Observations on a Hydrographic Section from the Azores to the Flemish Cap
Publisher: American Meteorological Society
Abstract: Continuous conductivity-temperature-depth-dissolved-oxygen (CTD) data are used to investigate the spatial distribution of fine and microstructure between the Azores and Flemish Cap. The CTD data are used to calculate a ...
Dianeutral Motion, Water Mass Conversion, and Nonlinear Effects on the Density Ratio in the Pacific Thermocline
Publisher: American Meteorological Society
Abstract: The averaged hydrography of Levitus has been used to form maps of various quantities that contribute to dianeutral advecion in the Pacific thermocline. On much of the ?26.50? neutral surface cabbeling and thermobaricity ...
Finescale Parameterizations of Turbulent Dissipation
Publisher: American Meteorological Society
Abstract: Fine- and microstructure data from a free fall profiler are analysed to test models that relate the turbulent dissipation rate (?) to characteristics of the internal wave field. The data were obtained from several distinct ...
