Blow-up of dyadic MHD models with forward energy cascade [PDF]
A particular type of dyadic model for the magnetohydrodynamics (MHD) with forward energy cascade is studied. The model includes intermittency dimension $\delta$ in the nonlinear scales. It is shown that when $\delta$ is small, positive solution with large initial data for either the dyadic MHD model or the dyadic Hall MHD develops blow-up in finite ...

THREE-DIMENSIONAL KINETIC-MHD MODEL OF THE GLOBAL HELIOSPHERE WITH THE HELIOPAUSE-SURFACE FITTING [PDF]
This paper provides a detailed description of the latest version of our model of the solar wind (SW) interaction with the local interstellar medium (LISM).

Multiwavelength Studies of MHD Waves in the Solar Chromosphere [PDF]
The chromosphere is a thin layer of the solar atmosphere that bridges the relatively cool photosphere and the intensely heated transition region and corona. Compressible and incompressible waves propagating through the chromosphere can supply significant

We performed a series of high-resolution (up to 1024^3) direct numerical simulations of hydro and MHD strong turbulence. We found that for simulations with normal viscosity the slopes for spectra of MHD are similar, although slightly more shallower than ...

Analytical Study of Certain Magnetohydrodynamic-alpha Models
In this paper we present an analytical study of a subgrid scale turbulence model of the three-dimensional magnetohydrodynamic (MHD) equations, inspired by the Navier-Stokes-alpha (also known as the viscous Camassa-Holm equations or the Lagrangian ...

MHD wave modes resolved in fine-scale chromospheric magnetic structures [PDF]
Within the last decade, due to significant improvements in the spatial and temporal resolution of chromospheric data, magnetohydrodynamic (MHD) wave studies in this fascinating region of the Sun's atmosphere have risen to the forefront of solar physics ...

Generalized MHD equations [PDF]
AbstractSolutions of the d-dimensional generalized MHD (GMHD) equations∂tu+u·∇u=−∇P+b·∇b−ν(−Δ)αu,∂tb+u·∇b=b·∇u−η(−Δ)βbare studied in this paper. We pay special attention to the impact of the parameters ν,η,α and β on the regularity of solutions. Our investigation is divided into three major cases: (1) ν>0 and η>0, (2) ν=0 and η>0, and (3) ν=0 and η=0 ...

Damping of MHD turbulence in partially ionized plasma: implications for cosmic ray propagation
We study the damping from neutral-ion collisions of both incompressible and compressible magnetohydrodynamic (MHD) turbulence in partially ionized medium. We start from the linear analysis of MHD waves applying both single-fluid and two-fluid treatments.
