& Zahn (1992), is assumed. In this case, a steady tachocline is formed in which the advection of angular momentum balances the Reynolds stresses. The horizontal component of turbulent viscosity required to match the thickness of the tachocline to that obtained by helioseismology. is estimated to be 5 x 10m2s I.the solar interior, pressure, density and temperature all decrease outward with radius (see gure 1. 1), but the radial entropy gradient changes sign at around 0. 7R. the solar tachocline pdf

Acoustic sounding of the Sun reveals that the variation of angular velocity with latitude is independent of depth in the convection zone. By contrast, deep within the radiative zone, the rotation appears to be rigid. The transition between the two rotation laws occurs in a thin, unresolved layer that we here call the tachocline.

They show that the width of the tachocline is then determined by the degree of anisotropy in the turbulence. Simulations carried out by Elliott (1997)conrmed this trend. An alternative solution was offered by Gough& McIntyre (1998).
The solar tachocline, a thin layer containing the strong radial differential rotation at the base of the convection zone has proven to be important for several reasons. the solar tachocline pdf PDF This paper discusses the role of a weak toroidal magnetic field in modifying the turbulent transport properties of stably stratified rotating turbulence in the tachocline.Rating: 4.54 / Views: 651
