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…
Tracing the early development of harmful algal blooms with the aid of Lagrangian coherent structures
M. J. Olascoaga, F. J. Beron-Vera, L. E. Brand +1
Several theories have been proposed to explain the development of harmful algal blooms (HABs) produced by the toxic dinoflagellate \emph{Karenia brevis} on the West Florida Shelf.…
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…
Linear waves and baroclinic instability in an inhomogeneous-density layered primitive-equation ocean model
F. J. Beron-Vera, M. J. Olascoaga, J. Zavala-Garay
We consider a multilayer generalization of Ripa's inhomogeneous-density single-layer primitive-equation model. In addition to vary arbitrarily in horizontal position and time, the…
Deep ocean influence on upper ocean baroclinic instability saturation
M. J. Olascoaga, F. J. Beron-Vera, J. Sheinbaum
In this paper we extend earlier results regarding the effects of the lower layer of the ocean (below the thermocline) on the baroclinic instability within the upper layer (above th…
Constrained-Hamiltonian Shallow-Water Dynamics on the Sphere
F. J. Beron-Vera
Salmon's nearly geostrophic model for rotating shallow-water flow is derived in full spherical geometry. The model, which results upon constraining the velocity field to the height…
