On the temperature profile at the surface of a rotating convection zone
Abstract
An analytical examination is presented of the effects of rotation of the sun on the largescale eddies on the solar surface. A meanfield approach is employed, and it is shown that rotation strongly affects the structure of the eddy conductivity tensor. The effects are manifested in a nonuniform temperature and/or heat flux profiles in regards to latitude, although direct observations cannot be made due to turbulent heat diffusion in the convective zone. The poleequator temperature difference is found to be proportional to the ratio of the Boltzmann flux to the portion of the eddy conductivity arising from smallscale turbulence. An analytical model is developed that involves two shells with constant but different conductivities, and serves to include the effects of the outer passive layer.
