On the Spectrum of Magnetohydrodynamic Turbulence
- The Astrophysical Journal Letters
, 2005
"... We propose a phenomenological model for incompressible magnetohydrodynamic turbulence. We argue that nonlinear-wave interaction weakens as the energy cascade proceeds to small scales, however, the anisotropy of fluctuations along the large-scale magnetic field increases, which makes turbulence stron ..."

Energy spectrum of quasigeostrophic turbulence
- Phys. Rev. Lett
, 2002
"... Abstract. We consider the energy spectrum of a quasi-geostrophic model of forced, rotating turbulent flow. We provide a rigorous a priori bound E(k) ≤ Ck−2 valid for wave numbers that are smaller than a wave number associated to the forcing injection scale. This upper bound separates this spectrum f ..."

THE ONSET SPECTRUM OF TURBULENCE
, 1979
"... A general theoryfor thefluctuation spectrumof the onset ofturbulence is developed, applying to systems that approach turbulence through acascadeof subharmonic bifurcations. Applied to Rayleigh—Bénard flow, we find excellent quantitative agreement with the recentexperimental data of Libchaber and Mau ..."

ENERGY SPECTRUM IN ROTATING TURBULENCE
"... The transition between three-dimensional and quasi-two-dimensional turbulence in a rotating frame is experimentally investigated. Turbulence is generated by rapidly towing a grid in a rotating water tank, and the velocity eld in a plane perpendicular to the rotation axis is measured by means of part ..."

Theories of convection and the spectrum of turbulence in the solar photosphere
, 2006
"... Abstract. Classical theories of turbulence do not describe accurately inertial range scaling laws in turbulent convection and notably fail to model the shape of the turbulent spectrum of solar photospheric convection. To understand these discrepancies, a detailed study of scale-by-scale budgets in t ..."

SPECTRA OF CONFORMAL TURBULENCE
, 1992
"... A set of different conformal solutions corresponding to a constant flux of squared vorticity is considered. Requiring constant fluxes of all inviscid vorticity invariants (higher powers of the vorticity), we come to the conclusion that the general turbulence spectrum should be given by Kraichnan’s e ..."

Simulations of MHD Turbulence in ISM
"... We simulate supersonic, magnetized, compressible, isothermal turbulence using ideal MHD. To represent physical conditions within molecular clouds, our runs possess Mach number as high as 10 and have Alfven Mach numbers (MA =vA) around unity. Here, We study the rate of energy dissipation as well as ..."
