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…
Morpho-kinematic and photoionization models of the multipolar structures in planetary nebula NGC 6572
Rahul Bandyopadhyay, Ramkrishna Das, Mudumba Parthasarathy +1
We have studied the planetary nebula (PN) NGC 6572 through 3D morpho-kinematic and photoionization modelling. The 3D morphology is reconstructed from the Hubble Space Telescope ima…
Energy exchanges between a two-dimensional front and internal wave modes
Subhajit Kar, Roy Barkan
Fronts and near-inertial waves are energetic motions in the upper ocean that can interact and provide a route for kinetic energy (KE) dissipation of balanced oceanic flows. A quasi…
An inverse technique for reconstructing ocean's density stratification from surface data
Subhajit Kar, Anirban Guha
In this article, we propose an inverse technique that accurately reconstructs the ocean's density stratification profile simply from free surface elevation data. Satellite observat…
Selection of axial dipole from a seed magnetic field in rapidly rotating dynamo models
Subhajit Kar
In this study, we investigate preferences of dipolar magnetic structure from a seed magnetic field in the rapidly rotating spherical shell dynamo models. In this study, we set up a…
Ocean bathymetry reconstruction from surface data using hydraulics theory
Subhajit Kar, Anirban Guha
Here we propose a technique that successfully reconstructs ocean bathymetry from the free surface velocity and elevation data. This technique is based on the principles of open-cha…
