Phenomenology of two-dimensional stably stratified turbulence under large-scale forcing
Abhishek Kumar, Mahendra K. Verma, Jai Sukhatmae
In this paper we characterize the scaling of energy spectra, and the interscale transfer of energy and enstrophy, for strongly, moderately and weakly stably stratified two-dimensio…
The advection-condensation model and water vapour PDFs
Jai Sukhatme, William R. Young
The statistically steady humidity distribution resulting from an interaction of advection, modeled as an uncorrelated random walk of moist parcels on an isentropic surface, and a v…
Nonlinear inertia-gravity wave-mode interactions in three dimensional rotating stratified flows
Mark Remmel, Jai Sukhatme, Leslie M. Smith
We investigate the dynamics of inertia-gravity wave modes in 3D rotating stratified fluids. We start by deriving a reduced PDE, the GGG model, consisting of only wave-mode interact…
Local and Nonlocal Dispersive Turbulence
Jai Sukhatme, Leslie M. Smith
We consider the evolution of a family of 2D dispersive turbulence models. The members of this family involve the nonlinear advection of a dynamically active scalar field, the local…
Vortical and Wave Modes in 3D Rotating Stratified Flows: Random Large Scale Forcing
Jai Sukhatme, Leslie M. Smith
Utilizing an eigenfunction decomposition, we study the growth and spectra of energy in the vortical and wave modes of a 3D rotating stratified fluid as a function of . Work…
Self-Similarity in Decaying Two-Dimensional Stably Stratified Adjustment
Jai Sukhatme, Leslie M. Smith
The evolution of large-scale density perturbations is studied in a stably stratified, two-dimensional flow governed by the Boussinesq equations. As is known, intially smooth densit…
