Zonal Jets as Transport Barriers in Planetary Atmospheres
F. J. Beron-Vera, M. G. Brown, M. J. Olascoaga +3
The connection between transport barriers and potential vorticity (PV) barriers in PV-conserving flows is investigated with a focus on zonal jets in planetary atmospheres. A pertur…
Persistent Transport Barrier on the West Florida Shelf
M. J. Olascoaga, I. I. Rypina, M. G. Brown +5
Analysis of drifter trajectories in the Gulf of Mexico has revealed the existence of a region on the southern portion of the West Florida Shelf (WFS) that is not visited by drifter…
On the Lagrangian Dynamics of Atmospheric Zonal Jets and the Permeability of the Stratospheric Polar Vortex
I. I. Rypina, F. J. Beron-Vera, M. G. Brown +3
The Lagrangian dynamics of zonal jets in the atmosphere are considered, with particular attention paid to explaining why, under commonly encountered conditions, zonal jets serve as…
Phase space structure of nonautonomous one-degree-of-freedom Hamiltonian systems with nontrivial time dependence
F. J. Beron-Vera, M. J. Olascoaga, M. G. Brown
It has been recently argued that near-integrable nonautonomous one-degree-of-freedom Hamiltonian systems are constrained by KAM theory even when the time-dependent (nonintegrable)…
Rays, modes, wavefield structure and wavefield stability
M. G. Brown, F. J. Beron-Vera, I. Rypina +1
Sound propagation is considered in range-independent environments and environments consisting of a range-independent background on which a weak range-dependent perturbation is supe…
Passive tracer patchiness and particle trajectory stability in incompressible two-dimensional flows
Francisco J. Beron-Vera, María J. Olascoaga, Michael G. Brown
Particle motion is considered in incompressible two-dimensional flows consisting of a steady background gyre on which an unsteady wave-like perturbation is superimposed. A dynamica…
