Coarse-grained local available potential energy
Jacob O. Wenegrat, Tomas Chor, Roy Barkan
The available potential energy (APE) of a fluid can be defined locally in space, providing useful insights into both the energetics and dynamics of stratified flows ranging from th…

Linear stability of an oceanic front at finite Rossby number
Subhajit Kar, Roy Barkan, John R. Taylor
Submesoscale currents in the ocean's mixed layer (ML), consisting of fronts, eddies, and filaments, are characterized by order one Rossby (Ro) and Richardson (Ri) numbers. These cu…

Spontaneous emission of internal waves by a radiative instability
Subhajit Kar, Roy Barkan, James C. McWilliams +1
The spontaneous emission of internal waves (IWs) from balanced mesoscale eddies has been previously proposed to provide a source of oceanic IW kinetic energy (KE). This study exami…
