Development of internal solitary waves in various thermocline regimes-a multi-modal approach
internal solitary waves various thermocline regimes multi-modal approach
2009/11/12
A numerical analysis is made on the appearance of oceanic internal solitary waves in a multi-modal setting. This is done for observed profiles of stratification from the Sulu Sea and the Bay of Biscay...
Profile of an Isopycnal Surface in the Main Thermocline of the Sargasso Sea
Isopycnal Surface Main Thermocline Sargasso Sea
2009/4/2
The vertical displacement and slope of an isopycnal surface (by which is meant a density surface of constant σt) are described spatially. The data were acquired by towing pressure, temperature and con...
Spring Thermocline Behavior in Lake Ontario During IFYGL
Spring Thermocline Behavior Lake Ontario During IFYGL
2009/3/26
A dynamical analysis is presented of some observations made during the International Field Year on the Great Lakes (IFYGL) on the north shore of Lake Ontario at Oshawa. The data analyzed relate to wat...
Nearshore Lake Currents Measured During Upwelling and Downwelling of the Thermocline in Lake Ontario
Nearshore Lake Currents Thermocline Lake Ontario
2009/3/24
The upwelling-downwelling cycles observed along the north shore of Lake Ontario have periods of about 12 to 16 days in length. Currents associated with the downwelling cycle are typically stronger. Th...
On the Equilibrium Shape of the Thermocline in a Shore Zone
Equilibrium Shape Thermocline Shore Zone
2009/3/9
The typical spring thermal regime of Lake Ontario shows a thermocline surface of either a “wedge” or of a “lens” shape persisting in the shore zone for a considerable period. The summer regime is char...
A linear model of the thermocline is examined for an ocean bounded by both eastern and western coasts. The analysis is carried out on a β-plane for an ocean in which diffusion of heat but not of momen...
A Study of Velocity Profiles Through the Main Thermocline
Velocity Profiles Main Thermocline
2009/3/7
A time series of velocity profiles derived from three methods are used to describe the variations of current in time and in the vertical. Absolute velocity profiles were Obtained by acoustically track...
Variations in the Intensity of Small-Scale Mixing in the Main Thermocline
Small-Scale Mixing Main Thermocline
2009/3/7
Three cruises to the same site in the central North Pacific (28°N, 155°W) found naked differences in the levels of small-scale turbulent activity as indicated by spectra of temperature profiles. Consi...
A Comparison of Finestructure Spectra from the Main Thermocline
Finestructure Spectra Main Thermocline
2009/3/7
Large numbers of STD casts taken during five cruises to the same location in the central North Pacific permitted the separation of the temperature profile into mean T¯ (z) and fluctuating T′(z) c...
Migrating Thermal Structure in a Freshwater Thermocline
Migrating Thermal Structure Freshwater Thermocline
2009/2/23
The vertical migration of thermal structure in freshwater thermoclines is investigated with theory and observations. The theory is for the wind-forced internal oscillations of a viscous, nonrotating, ...
A Wind-Driven Model Experiment of the Seasonal Cycle of the Main Thermocline in the Interior Midlatitude North Pacific
Wind-Driven Model Main Thermocline Seasonal Cycle Interior Midlatitude North Pacific
2009/2/23
A wind-driven model experiment is designed to test the effectiveness of the classical wind-driven theory of Veronis and Stommel (1956) in explaining the phase and amplitude of the seasonal cycle of th...
A Simple Ekman-Type Model for Predicting Thermocline Displacement in the Tropical Pacific
Ekman-Type Model Tropical Pacific Thermocline Displacement
2009/2/23
A linear model is developed for the near-equatorial zone to estimate wind-driven convergences in the near-surface viscous boundary layer. Using the winds observed during EASTROPAC, an attempt is made ...
Profiles of temperature microstructure have been found to exhibit strong intermittence in the distribution of χ, the rate of diffusive smoothing of temperature fluctuations. Records from the main ther...

Thermocline Response Interior Midlatitude Transient Atmospheric Forcing
2009/2/16
The Ekman pumping mechanism for altering the depth of the main thermocline in response to wind stress curl is tested in the central midlatitude North Pacific. According to this mechanism, the depth of...
On the Effect of Dissipation on Seasonal Thermocline Models

2009/2/11
This paper considers several parameterizations of dissipation in a Kraus-Turner (1967) seasonal mixed-layer model with no net annual surface buoyancy flux. By studying the behavior of the turbulent ki...
