Compressibility effects in a turbulent transport of temperature field
I. Rogachevskii, N. Kleeorin
Compressibility effects in a turbulent transport of temperature field are investigated applying the quasi-linear approach for small Péclet numbers and the spectral approach for…
Three-dimensional slow Rossby waves in rotating spherical density stratified convection
T. Elperin, N. Kleeorin, I. Rogachevskii
We develop a theory of three-dimensional slow Rossby waves in rotating spherical density stratified convection. The Rossby waves with frequencies which are much smaller than the ro…
Magnetic flux concentrations from turbulent stratified convection
P. J. Käpylä, A. Brandenburg, N. Kleeorin +2
(abridged) Context: The mechanisms that cause the formation of sunspots are still unclear. Aims: We study the self-organisation of initially uniform sub-equipartition magnetic fiel…
Intense bipolar structures from stratified helical dynamos
Dhrubaditya Mitra, A. Brandenburg, N. Kleeorin +1
We perform direct numerical simulations of the equations of magnetohydrodynamics with external random forcing and in the presence of gravity. The domain is divided into two parts:…
Mean-field and direct numerical simulations of magnetic flux concentrations from vertical field
A. Brandenburg, O. Gressel, S. Jabbari +2
Strongly stratified hydromagnetic turbulence has previously been found to produce magnetic flux concentrations if the domain is large enough compared with the size of turbulent edd…
Spontaneous formation of flux concentrations in a stratified layer
Koen Kemel, Axel Brandenburg, Nathan Kleeorin +2
The negative effective magnetic pressure instability discovered recently in direct numerical simulations (DNS) may play a crucial role in the formation of sunspots and active regio…
