On stochastic stability of regional ocean models with uncertainty in wind forcing
stochastic stability regional ocean models uncertainty in wind forcing
2009/11/3
A shallow-water model was used to understand model error induced by non-Gaussian wind uncertainty. Although the model was simple, it described a generic system with many degrees of freedom randomized ...
The Relationship Between Stability and Source Waters for a Section in the Northeast Atlantic
Stability Source Waters Northeast Atlantic
2009/4/2
The mean density structure in the Northeast Atlantic is described in terms of the stability frequency. Some dynamic considerations are given to account for the observed distribution and to indicate th...
On the Mixed Stability Program for Quasi-Geostrophic Ocean Currents
Quasi-Geostrophic Ocean Currents baroclinic currents
2009/3/26
A simple, two-layer, quasi-geostrophic model is used to investigate the stability of baroclinic currents confined to a finite length scale L in a basin of considerably larger dimension (4L). The curre...
On the Stability of the California Undercurrent off Vancouver Island
California Undercurrent Vancouver Island
2009/3/7
Recent satellite infrared imagery and hydrographic maps of the sea surface temperature of the northeast Pacific reveal a fairly regular pattern of cells or eddies that are aligned north-south about 15...
The Stability of Ocean Currents in Eddy-Resolving General Circulation Models
Ocean Currents Eddy-Resolving General Circulation Models
2009/2/23
The stability of currents generated in an oceanic eddy-resolving general circulation model EGCM (Holland, 1978) is investigated by solving the eigenvalue problem associated with the finite-difference ...
On the Stability of a Fluid with Specialized Density Stratification. Part II：Mixed Baroclinic-Barotropic Instability with Application to the Northeast Pacific
Density Stratification Mixed Baroclinic-Barotropic Instability Northeast Pacific
2009/2/18
Low-frequency motions (0.25 cpd) have recently been observed in Juan de Fuca Strait. The three-layer model developed in Part I of this paper is used to show that some of this activity may be due to an...
On the Stability of Spatially Irregular Coastal Flows, with Application to the Florida Current
Spatially Irregular Coastal Flows Florida Current
2009/2/18
A study is made of the propagation of continental shelf waves and barotropic Rossby waves in a steady, laterally sheared current of the form V + W, where 1 and W is a centered random function repres...
On the Stability of a Fluid with Specialized Density Stratification. Part I：Baroclinic Instability and Constant Bottom Slope
Specialized Density Stratification Baroclinic Instability Constant Bottom Slope
2009/2/16
A three-layer model is used to study the stability of large-scale oceanic zonal flows over topography. The mean density profile employed has upper and lower layers of constant densities ρ1* and ρ3*, r...
The Effect of a Bottom Boundary Layer on the Stability of a Baroclinic Zonal Current
Bottom Boundary Layer Baroclinic Zonal Current
2009/2/8
The effect of a depth-limited bottom boundary layer on the stability of a baroclinic zonal current is investigated. The model is of a two-layer quasi-geostrophic flow. Limiting the height of the bound...
Stability of Free Surface Ekman Layers
Free Surface Ekman Layers wavenumbers α independent parameters
2009/2/5
The stability of free surface, laminar Ekman layers is examined for both the homogeneous and the two-layer case. The eigenvalues of the homogeneous case depend upon the wavenumbers α and &ggr; and the...
The Baroclinic Stability of the Atlantic North Equatorial Current
Baroclinic Stability North Equatorial Current
2009/2/5
POLYMODE Array III, Cluster C, was a collection of four current meter moorings that were placed in the Atlantic North Equatorial Current for one year in May 1978. They were designed to look for indica...
The Effects of the Variations In Sea Surface Temperature and Atmospheric Stability in the Estimation of Average Wind Speed by SEASAT-SASS

2009/1/19
Wind speeds from the scatterometer (SASS) on the ocean observing satellite SEASAT averaged over 2° latitude by 2° longitude and a 92-day period are compared with wind speeds from ship reports in the w...
Double-Diffusive Interleaving. Part I：Linear Stability Analysis
Double-Diffusive Interleaving Linear Stability Analysis
2009/1/16
Quasi-horizontal interleaving between water masses is frequently observed in the frontal regions between different water masses where there are significant compensating isopycnal gradients of temperat...
