A semi-analytical pseudo-spectral method for 3D Boussinesq equations of rotating, stratified flows in unbounded cylindrical domains
Jinge Wang, Philip S. Marcus
We present a pseudo-spectral method for solving the three-dimensional Boussinesq equations in unbounded cylindrical domains, specifically tailored for rotating, stably stratified f…
Transient growth of a wake vortex and its initiation via inertial particles
Sangjoon Lee, Philip S. Marcus
The transient dynamics of a wake vortex, modelled as a strong swirling -vortex, are investigated with a focus on optimal transient growth driven by continuous eigenmodes associa…
Perturbation analysis of triadic resonance in columnar vortices: selection rules and the roles of external forcing and critical layers
Jinge Wang, Sangjoon Lee, Philip S. Marcus
The remarkable robustness of columnar vortices suggests the existence of fundamental constraints that prevent spontaneous disintegration. In this work, we investigate the weakly no…
Stable 3-dimensional Vortex Families Consistent with Jovian Observations Including the Great Red Spot
Aidi Zhang, Philip S. Marcus
Detailed observations of the velocities of Jovian vortices exist at only one height in the atmosphere, so their vertical structures are poorly understood. This motivates this study…
