Effects of boundary conditions on the dynamics of the solar convection zone
Reza Tavakol, Eurico Covas, David Moss +1
Recent analyses of the helioseismic data have produced evidence for a variety of interesting dynamical behaviour associated with torsional oscillations. What is not so far clear is…
Torsional oscillations in the solar convection zone
Eurico Covas, Reza Tavakol, David Moss +1
Recent analysis of the helioseismic observations indicate that the previously observed surface torsional oscillations extend significantly downwards into the solar convection zone.…
The influence of geometry and topology on axisymmetric mean-field dynamos
E. Covas, R. Tavakol, A. Tworkowski +3
We study the changes in the dynamical behaviour of axisymmetric spherical mean-field dynamo models produced by changes in their geometry and topology, by considering a two paramete…
Mean Field Dynamos with Algebraic and Dynamic alpha-Quenchings
A. Tworkowski, E. Covas, R. Tavakol +1
Calculations for mean field dynamo models (in both full spheres and spherical shells), with both algebraic and dynamic --quenchings, show qualitative as well as quantitative dif…
Axisymmetric mean field dynamos with dynamic and algebraic --quenchings
Eurico Covas, Reza Tavakol, Andrew Tworkowski +1
We study axisymmetric mean field spherical and spherical shell dynamo models, with both dynamic and algebraic --quenchings. Our results show that there are qualitative as well a…
Robustness of truncated alpha-Omega dynamos with a dynamic alpha
Eurico Covas, Andrew Tworkowski, Reza Tavakol +1
In a recent work (Covas et al. 1997), the behaviour and the robustness of truncated dynamos with a dynamic were studied with respect to a number of changes in the driving…
