Models for a Differentially Rotating Solar Convection Zone

Axisymmetric mean field models of the sun's differential rotation are considered which employ a real solar envelope. The models include the mixing length theory of convective energy transport of Vitense (1953). The driving terms included in the mean equations are second order correlations of velocity and temperature fluctuations. Two classes of models are investigated: (1) models with anisotropic viscosity, a special form of driving by Reynolds stresses; and (2) models with the latitude-dependent heat transport which arises from the influence of rotation upon convection and which generates meridional circulation and differential rotation.
