Numerical model of thermal convection in the upper mantle of the earth under continental lithosphere
The spatial-temporal evolution of thermal convection in the
continental upper mantle is numerically investigated by
the predictor-corrector method with majorant splitting scheme on the predictor (for the equation of temperature transport) and the iterating method of stabilizing corrections (to find the stream function from the equation of the fourth order with variable coefficients). Lithosphere is presented by rigid conductive layer with constant thickness (120 km), the viscosity of the upper mantle depends on the depth. The non-slip conditions are given at the bottom of the lithosphere, and convection is excited by constant heat flux from the lower boundary. At this boundary conditions the structure of the convection in 7000 M years attains to the steady state as one long cell.
