| Research Abstract |
I developed a finite-volume based three-dimensional mantle convection simulation code using the Yin-Yang grid, which enables me to successfully simulate convection with the temperature- and pressure-dependent viscosity. Using this code, I clarified that the degree-one and degree-two dominant convection is basic structures of mantle convection in the terrestrial planets. Then, I developed the mantle convection model with the deformable, mobile continental lithosphere to obtain the numerical results realizing the supercontinental cycle.
