Energy budgets in Charney-Hasegawa-Mima and surface quasigeostrophic turbulence.

چکیده
We study energy transfer in unbounded Charney-Hasegawa-Mima and surface quasigeostrophic turbulence. The possible inverse-cascading quantities in these systems are, respectively, I identical with integral ( infinity )(0)k(-2)E(k) dk and J identical with integral ( infinity )(0)k(-1)E(k) dk, where E(k) is the kinetic energy spectrum. The supposed direct-cascading quantities for both surface quasigeostrophic and Navier-Stokes turbulence are shown to be bounded. We derive a constraint on E(k) for the surface quasigeostrophic system.

Impeded inverse energy transfer in the Charney – Hasegawa – Mima model of quasi - geostrophic flows
The behaviour of turbulent flows within the single-layer quasi-geostrophic (Charney– Hasegawa–Mima) model is shown to be strongly dependent on the Rossby deformation wavenumber λ (or free-surface elasticity). Herein, we derive a bound on the inverse energy transfer, specifically on the growth rate dl/dt of the characteristic length scale l representing the energy centroid. It is found that dl/d...
متن کاملTriple cascade behaviour in QG and drift turbulence and generation of zonal jets
We study quasi-geostrophic turbulence and plasma drift turbulence within the Charney-Hasegawa-Mima (CHM) model. We focus, theoretically and using numerical simulations, on conservation of zonostrophy and on its role in the formation of the zonal jets. The zonostrophy invariant was first predicted in [1, 2] in two special cases – large-scale turbulence and anisotropic turbulence. Papers [1, 2] a...
متن کاملAn Energy Estimate for a Perturbed Hasegawa{mima Equation
It is commonly believed that drift waves and drift-wave turbulence play a major role in the understanding of anomalous transport at the plasma edge of a tokamak fusion reactor. A one-eld equation describing the electrostatic potential uctuations in this regime is the so-called Hasegawa{Mima equation. If this equation is driven by some instability and damped by some hyperviscous term, the energy...
متن کاملAnisotropic shell model of turbulence.
An anisotropic shell model has been proposed for two-dimensional (2D) turbulence. It is similar to the 2D version of the Gledzer-Ohkitani-Yamada model but with the angular variable in wave-number space divided into three distinct directions representing structures elongated in different directions. In the case when the drive is isotropic the usual isotropic solution is recovered as the fixed po...
متن کاملAnomalous transport in Charney-Hasegawa-Mima flows.
The transport properties of particles evolving in a system governed by the Charney-Hasegawa-Mima equation are investigated. Transport is found to be anomalous with a nonlinear evolution of the second moments with time. The origin of this anomaly is traced back to the presence of chaotic jets within the flow. All characteristic transport exponents have a similar value around mu = 1.75, which is ...
