Description:
The onset of convection in a rotating spherical shell at increasing
rotation rate (Taylor number 10^{7}, 10^{8},
10^{9}, 10^{10}, 10^{11}, 10^{12}, from left
to right and top to bottom).
The convection columns are aligned with the axis of rotation and their
number increases with increasing Taylor numbers.
The simulation assumes the Boussinesq equation and the equations are
linearised at the onset of convection.
A uniform distrubution of heat sources in assumed in the fluid.
What is plotted:
Iso surfaces of the axial component of vorticity, color coded with the
temperature perturbation with respect to the steady temperature profile.
Ekman boundary layers have been filtered out on the first line to enhance
readability.
