Nonlinear Evolution of a Baroclinic Wave and Imbalanced Dissipation
Balasubramanya T. Nadiga
We consider the nonlinear evolution of an unstable baroclinic wave in a regime of rotating stratified flow that is of relevance to interior circulation in the oceans and in the atm…
The Equivalence of the Lagrangian-Averaged Navier-Stokes-α Model and the Rational LES model in Two Dimensions
Balasubramanya T. Nadiga, Freddy Bouchet
In the Large Eddy Simulation (LES) framework for modeling a turbulent flow, when the large scale velocity field is defined by low-pass filtering the full velocity field, a Taylor s…
On Zonal Jets in Oceans
Balu Nadiga
We find that in parameter regimes relevant to the recently observed alternating zonal jets in oceans, the formation of these jets can be explained as due to an arrest of the turbul…
Scaling properties of an inviscid mean-motion fluid model
Balasubramanya T. Nadiga
An inviscid two-dimensional fluid model with nonlinear dispersion that arises simultaneously in coarse-grained descriptions of the dynamics of the Euler equation and in the descrip…
