Lake in a Bottle:A Laboratory Demonstration of the Unusual Stability Properties of Freshwater
Lake in a Bottle Unusual Stability Properties Freshwater
2015/7/13
Using simple laboratory gear, students can simulate the stratification properties of a freshwater lake and the impact of salt on the relationship between temperature and density. Because some students...
Stability and consistency of nonhydrostatic free-surface models using the semi-implicit
theta-method stability accuracy artificial damping free surface nonhydrostatic pressure ocean modeling
2015/6/30
The -method is a popular semi-implicit finite-difference method for simulating free-surface flows. Problem stiffness, arising because of the presence of both fast and slow timescale processes, is eas...
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 ...
An Investigation of Longitudinal Motion of the Slender-type Body at Fully Submerged CondituinPart 3 On the Experimental and Empirical Estimation Method of the Hydrodynamic Stability Derivatives
Longitudinal Motion Slender-type Body Hydrodynamic Stability Derivatives
2009/4/29
This paper consists of two parts. The first part is on the outline of renewd large forced motion machanism to be used in the maneuvering test on submerged body and surface ship model in the large towi...
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...

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 ...

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...
