Models for strongly-nonlinear evolution of long internal waves in a two-layer stratification
strongly-nonlinear evolution long internal waves two-layer stratification
2009/11/2
Models describing the evolution of long internal waves are proposed that are based on different polynomial approximations of the exact expression for the phase speed of uni-directional, fully-nonlinea...
The seasonal stratification in lakes is examined by a qualitative evaluation of
important physical processes and with the aid of a mathematical model. From
the description of the physical processes ...
On Currents and Vertical Mixing in Lake Ontario during Summer Stratification
Currents and Vertical Mixing Lake Ontario Summer Stratification
2009/10/26
Currents and vertical mixing characteristics were investigated on the basis of
time series of current meter and temperature data from a summer-stratified
period in Lake Ontario. The experimental set...
Extending the Similarity Theory for Atmospheric Boundary Layers: Contribution from Background Stratification
Atmospheric boundary layer similarity theory turbulence stratification effects
2009/6/10
The structure of the atmospheric boundary layer has traditionally been described using only surface fluxes and the Coriolis parameter. We review here the proposal of Kitaigorodskii (1988) and Kitaigor...
The role of diagenisis in the hydrogeological stratification of carbonate aquifers：an example from the chalk at Fair Cross, Berkshire, UK
hydrogeological stratification carbonate aquifers Fair Cross
2009/6/8
Carbonate rocks form important aquifers in many parts of the world and in north-west Europe the Chalk is a primary source of potable water. When flushed with relatively fresh groundwaters, the Chalk ...
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...
A Criterion for Thermal Stratification in a Wind-Mixed System
Thermal Stratification Wind-Mixed System
2009/2/16
The onset of thermal stratification in an isohaline, wind-mixed water body is shown, by a simple model and observations, to be determined by the parameter u*3/hB′, where u* is the friction velocity of...
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...
On the Influence of Stratification and Continental Shelf and Slope Topography on the Dispersion of Subinertial Coastally Trapped Waves
Continental Shelf Slope Topography Subinertial Coastally Trapped Waves
2009/2/6
The behavior of subinertial, coastally trapped free waves in a continuously stratified ocean is examined using a two-slope topography in which the continental shelf and slope are each represented by a...
The characteristics of long, gravest mode trench waves in the presence of realistic stratification are investigated. Two examples are computed, representing cases with widely differing importance of b...
On the Role of Interior Mixing and Air-Sea Fluxes in Determining the Stratification and Circulation of the Oceans
Interior Mixing Stratification Circulation Air-Sea Fluxes
2009/1/12
The problem of determining the (eastern boundary) basic stratification and the buoyancy-driven circulation of the oceans is addressed. A global integral constraint relating the interior stratification...
Solutions of the Ideal Fluid Thermocline with Continuous Stratification
Ideal Fluid Thermocline Continuous Stratification
2009/1/10
From an examination of possible ways to satisfy the essential upper boundary conditions, a general way to solve the ideal fluid thermocline is proposed. Through specifying the functional relation betw...
Long-Term Observations on the Southern Flank of Georges Bank. Part I：A Description of the Seasonal Cycle of Currents, Temperature, Stratification, and Wind Stress
Long-Term Observations Georges Bank Seasonal Cycle Wind Stress
2009/1/7
Nearly continuous current measurements at 45 and 75 m were made from May 1975 to March 1979 at 40°51′N, 67°24′W on the southern flank of Georges Bank in water 85 m deep. Measurements at 15 and 84 m we...
The Effect of Varying Stratification on Low-Frequency Equatorial Motions
Low-Frequency Equatorial Motions equatorial wave phenomena
2009/1/5
A formalism is developed to examine the effect of zonally varying stratification on equatorial wave phenomena; an effect present in the real ocean but neglected from standard linear theory. The approa...
A One-Dimensional Time-Dependent Model for the Vertical Stratification of the Upper Arctic Ocean
One-Dimensional Time-Dependent Model Vertical Stratification Upper Arctic Ocean
2008/12/30
A one-dimensional time-dependent model of the upper Arctic Ocean is presented. It describes the circulation above a dynamically passive reservoir of Atlantic water. The model is driven by freshwater r...
