On the Detection of “Inertial” Waves with Pycnocline Followers
“Inertial” Waves Pycnocline Followers
2009/3/9
The vertical displacements associated with oscillations near the local inertial frequency f, in a stratified ocean, are found to be significant, even very close to f. For a frequency, ω=(1+)f, the rat...
Variability of Potential Energy, Dynamic Height and Salinity in the Main Pycnocline of the Western North Atlantic
Potential Energy Main Pycnocline Western North Atlantic
2009/2/13
Hydrographic data in the upper 2 km from the period 1914–73 have been analyzed in the western North Atlantic (22–36°N, 66–74°W). Expendable bathythermograph (XBT) data were also analyzed and compared ...
Large-Scale Vertical Eddy Diffusion in the Main Pycnocline of the Central North Pacific
Large-Scale Vertical Central North Pacific Eddy Diffusion
2009/2/9
Indirect procedures are used to estimate the latitudinal distribution of the large-scale vertical eddy diffusivity coefficient in the main pycnocline from the interannual change in Tθ, ρθ structure of...
A Model for the Seasonal Pycnocline in Rotating Systems with Application to the Baltic Proper
Seasonal Pycnocline Baltic Proper Rotating Systems
2009/1/16
A one-dimensional seasonal pycnocline model, primarily intended for use in long-term circulation models, is developed. The model is of the two-layer (integral) type with a turbulent, well mixed surfac...
Effects of Alongshore Wind Stress at the Eastern Boundary on Circulation in the Ocean Pycnocline
Alongshore Wind Stress Eastern Boundary Ocean Pycnocline
2008/12/22
An alongshore wind stress is applied at the eastern boundary of an ocean model, and its effects on the structure of the circulation in the ventilated pycnocline are studied. The offshore surface Ekman...
Convective Building of a Pycnocline：Laboratory Experiments
Convective Building ycnocline Laboratory Experiments
2008/12/3
The convective building of a pycnocline is examined using a laboratory model forced by surface fluxes of saline water at one end and fresh water at the other. A deep recirculation evolves in the tank,...
Convective Building of a Pycnocline：A Two-Dimensional Nonhydrostatic Numerical Model
Two-Dimensional Nonhydrostatic Numerical Model balanced salinity dipole
2008/11/18
The convective building of a pycnocline is examined using a two-dimensional nonhydrostatic numerical model forced by a balanced salinity dipole (source and sink). Although the forcing fields are stead...
Interior Pycnocline Flow from the Subtropical to the Equatorial Pacific Ocean
Interior Pycnocline Flow Subtropical Equatorial Pacific Ocean
2008/7/25
Interior circulation pathways from the subtropics to the equator are markedly different in the Northern and Southern Hemispheres of the Pacific Ocean. In the North Pacific the pycnocline shoals and st...
A Basinwide Estimate of Vertical Mixing in the Upper Pycnocline: Spreading of Bomb Tritium in the North Pacific Ocean
Basinwide Estimate Vertical Mixing Upper Pycnocline Bomb Tritium North Pacific Ocean
2008/7/21
The vertical diffusivity KV in the upper half-kilometer of the North Pacific subtropical pycnocline is estimated from observations of the spreading rate of anthropogenic tritium. The calculation is ba...
Low-Frequency Pycnocline Depth Variability at Ocean Weather Station P in the Northeast Pacific
Low-Frequency Pycnocline Depth Variability Ocean Weather Station Northeast Pacific
2008/6/23
Low-frequency variability of the depth of the main pycnocline at Ocean Weather Station P and over the northeast Pacific is examined in terms of the one-dimensional response to local Ekman pumping acco...
Turbulent layering beneath the pycnocline in a strongly stratified pit-lake
Turbulent layering pycnocline strongly stratified pit-lake
2014/5/8
Temperature microstructure observations from a pit lake show alternate layers of high and low turbulence beneath a very strong pycnocline. The layers were clearly defined, around 0.3-0.5 m thick, and ...
