Conserved Pseudomomenta in Linear Quasigeostrophic Fluid Flows From Noether's Theorem
Dusan Begus, Chenyu Zhang, J. B. Marston
Hamiltonian and Lagrangian formulations for the two-dimensional quasi-geostrophic equations linearized about a zonally-symmetric basic flow are presented. The Lagrangian and Hamilt…
Statistical equilibrium principles in 2D fluid flow: from geophysical fluids to the solar tachocline
Peter B. Weichman, J. B. Marston
An overview is presented of several diverse branches of work in the area of effectively 2D fluid equilibria which have in common that they are constrained by an infinite number of…
Direct Statistical Simulation of the Busse Annulus
Jeffrey S. Oishi, Keaton J. Burns, J. B. Marston +1
We consider direct statistical simulation (DSS) of a paradigm system of convection interacting with mean flows. In the Busse Annulus model zonal jets are generated through the inte…
The Generalized Quasilinear Approximation: Application to Zonal Jets
J. B. Marston, G. P. Chini, S. M. Tobias
Quasilinear theory is often utilized to approximate the dynamics of fluids exhibiting significant interactions between mean flows and eddies. In this paper we present a generalizat…
Exact Equal Time Statistics of Orszag-McLaughlin Dynamics By The Hopf Characteristic Functional Approach
Ookie Ma, J. B. Marston
By employing Hopf's functional method, we find the exact characteristic functional for a simple nonlinear dynamical system introduced by Orszag. Steady-state equal-time statistics…
