Abstract: The formation of nonlinear eddies in unstable 2½-layer, quasigeostrophic jets is investigated using a piecewise constant potential vorticity, ?contour dynamical? model. Both infinite and semi-infinite jet dynamics are ...

Abstract: In this work, Pratt and Stern?s quasigeostrophic, 1½-layer, infinite jet model is connected to a western boundary by a system of two converging boundary currents. The model has a piecewise constant potential vorticity ...
