Frontogenesis and Frontal Progression of a Trapping-Generated Estuarine Convergence Front and Its Influence on Mixing and Stratification
Front Frontogenesis Trapping Convergence front Lateral circulation
2015/6/30
Estuarine fronts are well known to influence transport of waterborne constituents such as phytoplankton and sediment, yet due to their ephemeral nature, capturing the physical driving mechanisms and t...
Stratification and horizontal exchange in Lake Victoria, East Africa
Lake Victoria East Africa
2014/11/28
We characterize stratification patterns over diel, seasonal, and annual time scales in inshore and offshore
regions of Lake Victoria, East Africa; determine conditions leading to horizontal exchanges...

Mixing and stratification in lakes of varying horizontal length scales: Scaling arguments and energy partitioning
Mixing stratification varying horizontal length scales Scaling arguments energy partitioning
2014/4/17
This work analyzes the effects that changes in the surface area of stratified lakes have on the partitioning of energy among different pools, and, ultimately, on the strength of thermalstratification....
Effects of seasonal stratification on turbulent mixing in a hypereutrophic coastal lagoon
Effects of seasonal stratification turbulent mixing a hypereutrophic coastal lagoon
2014/4/16
Seasonal variations in vertical turbulent mixing rates, density structure, inorganic nutrient concentrations, and phytoplankton biomass were investigated in a shallow, tidally choked coastal lagoon. T...
Erratum: Chemical stratification in thermally stratified lakes: A chloride mass balance model
Chemical stratification thermally stratified lakes A chloride mass balance model
2014/4/17
The effect of this correction can best be appreciated by defining the non-dimensional variablesB*5BaandT*5(T(B)2Th)/(Te2Th) and plotting these as a function ofm(Fig. 2). Values ofB*from Eqs. 2 and 3 c...
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...

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...
