WebApr 19, 2011 · This is despite the kinematic viscosity being somewhat greater than χ. We discuss how the confinement layers s at each pole might fit into a global dynamical picture of the solar tachocline. That picture, in turn, suggests a new insight into the early Sun and into the longstanding enigma of solar lithium depletion. WebThe tachocline is mysterious both for its origin and its dynamical influence, and understanding these will be breakthrough science. Helioseismic inferences locate the tachocline at ∼0.7 R sun with a width of ∼0.04 R sun, although there is variation with latitude ( e.g. Corbard et al., 2001; Howe, 2009 ).
