Dynamics of Potential Vorticity Fronts and Eddy Detachment
Potential Vorticity Fronts Eddy Detachment
2009/1/12
The formation and detachment of quasi-geostrophic eddies in a 1½ layer jet is studied using a piecewise uniform potential vorticity model. A vorticity front separates the two pieces, and thus t...
Meandering and Eddy Detachment According to a Simple（Looking）Path Equation
Eddy Detachment Simple（Looking）Path Equation Nonlinear meandering
2009/1/6
Nonlinear meandering and “pinching off” process are investigated by solving the path equation As shown by Pratt and Stern, this dimensioned equation determines the center line latitude l of a slowly-v...
Topographic Forcing of Coastal Mesoscale Phenomena：Filamentation, Vortex Formation, and Eddy Detachment
Filamentation Vortex Formation Eddy Detachment Coastal Mesoscale Phenomena
2008/12/16
Using the methodology of contour dynamics on a quasigeostrophic model, the nonlinear evolution of a coastal potential vorticity front over a Gaussian topographic feature in the presence of an overlyin...
