A New Second-Order Turbulence Closure Scheme for Modeling the Oceanic Mixed Layer
Oceanic Mixed Layer Second-Order Turbulence
2008/10/27
A new second-order turbulence closure scheme is proposed for the oceanic mixed layer. The scheme is similar in complexity to a Mellor–Yamada level 2.5 scheme in that the turbulent kinetic energy is th...
Nonlinear Reflection of Internal Waves at a Density Discontinuityat the Base of the Mixed Layer
Internal Waves Mixed Layer
2008/10/27
Internal waves propagating with an upward component of group velocity toward the ocean surface are reflected at the base of the mixed layer. A simple model is constructed to examine nonlinear aspects ...
Internal Swell Generation: The Spatial Distribution of Energy Flux from the Wind to Mixed Layer Near-Inertial Motions
Spatial Distribution Energy Flux Mixed Layer Near-Inertial Motions
2008/8/12
The energy flux from the wind to inertial mixed layer motions is computed for all oceans from 50°S to 50°N for the years 1996–99. The wind stress, τ, is computed from 6-h, 2.5°-resolution NCEP–NCAR gl...

Turbulent Kinetic Energy Dissipation Rate Equatorial Mixed Layer
2008/7/21
The authors apply a one-dimensional mixed layer model, based on second moment closure of turbulence, to study the characteristics of turbulence in the equatorial mixed layer. In particular, they focus...
Ventilated Thermocline Strongly Affected by a Deep Mixed Layer: A Theory for Subtropical Countercurrent
Ventilated Thermocline Deep Mixed Layer Subtropical Countercurrent
2008/7/11
The mixed layer thickness generally increases in the northward direction, but its change seems to occur rather sharply in a narrow transition zone, referred to as a mixed layer front here. The author ...
A Generalized Depth-Integrated Model of the Oceanic Mixed Layer
AGeneralized Depth-Integrated Model Oceanic Mixed Layer
2008/7/10
A generalized depth-integrated model of the oceanic mixed layer is developed by considering the heat and energy budgets of the upper ocean. Unlike the Kraus–Turner-type bulk models, the assumptions of...
Tropical Pacific Ocean Mixed Layer Heat Budget: The Pacific Cold Tongue
Tropical Pacific Ocean Mixed Layer Heat Budget The Pacific Cold Tongue
2008/7/4
Data from satellite-tracked drifting buoys and VOS/XBT profiles for the years 1979–95 were used to evaluate the seasonal cycle of how major oceanic processes redistribute heat in the cold tongue regio...
The 3D Oceanic Mixed Layer Response to Hurricane Gilbert
3D Oceanic Mixed Layer Response Hurricane Gilbert
2008/6/30
Upper-ocean heat and mass budgets are examined from three snapshots of data acquired during and after the passage of Hurricane Gilbert in the western Gulf of Mexico. Measurements prior to storm passag...
Wind-Forced Upwelling: The Role of the Surface Mixed Layer
Wind-Forced Upwelling Surface Mixed Layer
2008/6/30
A numerical study is made of the dynamics of the circulation that arises from forcing by a steady, uniform alongshore wind over a uniform zonal shelf in the Southern Hemisphere. The results show that ...
