Effect of a Viscosity Interface at 1000 km Depth on Mantle Circulation

  • Hana ČIžková
  • Ondŕej Čadek


We present the preliminary results of axisymmetric numerical simulations of thermal convection in the mantle with a phase transition boundary at 660 km depth and a viscosity interface at 1000 km depth. The results, obtained for Ra = 2 × 10 6 , are compared with the case when both the phase and the viscosity boundaries are located at the same depth of 660 km.
