ON LARGE-SCALE SOLAR CONVECTION,

Abstract

The paper examines the effects of rotation about a vertical axis on thermal convection with a simple model in which an inviscid, incompressible fluid of zero thermal conductivity and electrical resistivity is contained in a thin annulus of rectangular cross-section. The initial steady state assumed is one of no motion relative to the rotating frame with constant (unstable) vertical temperature gradient and uniform toroidal magnetic field. Small periodic disturbances are then introduced and the linearized perturbation equations solved. The second order mean circulations and magnetic fields that are forced by non-zero Reynolds and thermal stresses and magnetic field transports are also determined. The solutions have several properties which are relevant to large-scale solar phenomena if giant long-lived convection cells exist on the sun. (Author)
