Evolution of a Potential Vorticity Front over a Topographic Slope
Potential Vorticity Front Topographic Slope
2008/12/24
Using the methodology of contour dynamics, the evolution of an interface separating two regions of constant potential vorticity is considered. The model equations are those for barotropic nondivergent...
Mean Flow Evolution of a Baroclinically Unstable Potential Vorticity Front
Mean Flow Evolution Baroclinically Unstable Potential Vorticity Front
2008/7/8
Quasi-linear theory and numerical models are used to study the mean flow modification of a two-layer shallow water baroclinically unstable flow as a function of Rossby number. This flow has an upper-l...
The Cross-Stream Potential Vorticity Front and Its Role in Meander-Induced Exchange in the Gulf Stream
Cross-Stream Potential Vorticity Front Meander-Induced Exchange Gulf Stream
2008/6/9
The potential vorticity (PV) front observed in the upper thermocline at the northern edge of the Gulf Stream has been thought of as an inhibitor to lateral motion of parcels on isopycnals. The role of...
