Reynolds stresses -: dependence on latitude

We present some results of three-dimensional hydrodynamic simulations of a compressible flow under the influence of rotation. The code implements a three-layer (stably-unstably-stably stratified) rectangular box placed at various latitudes in a convection zone of a star. We focus on the Reynolds stresses Q(ij) = < u(i)'u(j)'> which in mean-field models have a crucial influence on angular momentum transport and differential rotation. Especially we examine the occurrence of a strong peak of Q(theta phi) at low latitude very close to the equator, which may have implications to the theory of the angular velocity profile observed on the Sun.
