Generation Model of a Spatially Limited Vortex in a Stratified Unstable Atmosphere
O. G. Onishchenko, S. N. Artekha, F. Z. Feygin +1
This paper presents a new model for the generation of axisymmetric concentrated vortices. The solution of a nonlinear equation for internal gravity waves in an unstable stratified…
Cascade processes in rapidly rotating turbulence
M. Yu. Reshetnyak, O. Pokhotelov
The process of the kinetic energy and kinetic helicity transfer over the spectrum in an incompressible, rapidly rotating turbulent flow is considered. An analogue of the Fjortoft t…
Growth of the inner core in the mean-field dynamo model
M. Yu. Reshetnyak
Application of Parker's dynamo model to the geodynamo with the growing inner core is considered. It is shown that decrease of the inner core size, where intensive magnetic field ge…
Parker's model in geodynamo
M. Reshetnyak
We consider how information on geostrophic flows in the planetary cores, taken from 3D simulations in the sphere, can be used in 2D Parker's geodynamo model with the simple forms o…
Kinetic energy cascades in quasi-geostrophic convection in a spherical shell
Maxim Reshetnyak, Pavel Hejda
We consider triadic nonlinear interaction in the Navier-Stokes equation for quasi-geostrophic convection in a spherical shell. This approach helps understanding the origin of kinet…
Parker's dynamo and geomagnetic reversals
M. Reshetnyak, D. Sokoloff
Fluctuations of the alpha-effect which break equatorial symmetry of the flow in the kinematic Parker's dynamo are considered. We show, that even small (a few percents) fluctuation…
Nonlinearity in a dynamo
P. Hejda, M. Reshetnyak
Using a rotating flat layer heated from below as an example, we consider effects which lead to stabilizing an exponentially growing magnetic field in magnetostrophic convection in…
Direct and inverse cascades in the geodynamo
M. Reshetnyak, P. Hejda
The rapid rotation of planets causes cyclonic thermal turbulence in their cores which may generate the large-scale magnetic fields observed outside the planets. We consider the mod…
Stability problem in dynamo
M. Reshetnyak
It is shown, that the saturated -effect taken from the nonlinear dynamo equations for the thin disk can still produce exponentially growing magnetic field in the case, when this…
Effects of anisotropy in geostrophic turbulence
P. Hejda, M. Reshetnyak
The Boussinesq model of convection in a flat layer with heating from below is considered. We analyze the effects of anisotropy caused by rapid rotation in physical and wave spaces…
