RISA Relationship between Potential Vorticity and Zonal Wind on Jupiter
Publisher: American Meteorological Society
Abstract: We present evidence from analysis of Voyager data and numerical experiments that in Jupiter's troposphere at midlatitudes the potential vorticity is given simply by the reciprocal of the streamfunction. This relationship ...
Potential Vorticity and Layer Thickness Variations in the Flow around Jupiter's Great Red Spot and White Oval BC
Publisher: American Meteorological Society
Abstract: Layer thickness variations in Jupiter's atmosphere are investigated by treating potential vorticity as a conserved tracer. Starting with the horizontal velocity field measured from Voyager images, fluid trajectories around ...
Jupiter's Great Red Spot as a Shallow Water System
Publisher: American Meteorological Society
Abstract: Most current models of Jupiter's Great Red Spot (GRS) are cast in terms of a two-layer model, where a thin upper weather layer, which contains the vortex, overlies a much deeper layer, which is meant to represent the ...
The Emergence of Multiple Robust Zonal Jets from Freely Evolving, Three-Dimensional Stratified Geostrophic Turbulence with Applications to Jupiter
Publisher: American Meteorological Society
Abstract: Three-dimensional numerical simulations of freely evolving stratified geostrophic turbulence on the ? plane are presented as a simplified model of zonal jet formation on Jupiter. This study samples the parameter space that ...
Ertel Potential Vorticity versus Bernoulli Potential on Approximately Neutral Surfaces in the Antarctic Circumpolar Current
Publisher: American Meteorological Society
Abstract: We investigate the relationship between Ertel potential vorticity Q and Bernoulli potential B on orthobaric density surfaces in the Antarctic Circumpolar Current (ACC), using the Southern Ocean State Estimate. Similar to ...
