A primitive equation, eddy-resolving numerical model is used to study the inherent time scales of variability in the subtropical ocean, assuming temporally constant surface forcing. Three primary scal...
The Influence of Air–Sea Interaction on the Ventilated Thermocline
Air–Sea Interaction Ventilated Thermocline
2009/1/4
Air–Sea interaction influences the ventilated thermocline by forcing the mixed layer to deepen and cool poleward. When there is flow from the mixed layer into the interior, the mixed-layer depth and d...
Matching a Ventilated Thermocline Model with Inertial Western Boundary Currents
Ventilated Thermocline Model Inertial Western Boundary Currents western boundary region
2008/12/30
A two-layered ventilated thermocline model is matched with inertial western boundary currents in the southern part of the western boundary region. For general cases the western boundary currents break...
The Role of Finite Mixed-Layer Thickness in the Structure of the Ventilated Thermocline
Finite Mixed-Layer Thickness Ventilated Thermocline
2008/12/24
A model of the ventilated thermocline consisting of three adiabatic layers surmounted by a mixed layer of finite thickness is presented. The mixed-layer depth density increase continuously northward, ...
The time dependence of the ventilated thermocline is examined via analytical and numerical means. The original Henderschott model is modified such that the outcrops all occur on the same geopotential ...
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 ...
Climate Variability Inferred from a Layered Model of the Ventilated Thermocline
Climate Variability Inferred Layered Model Ventilated Thermocline
2008/7/10
Climate variability of a layered model of the ventilated thermocline is studied. Assuming the Ekman pumping is unchanged, cooling (heating) causes a southward (northward) shift of the outcrop line and...
