Péclet number distribution at present (time = 1.3E5 a) showing the relative importance of heat advection versus conduction with a constant surface temperature in a the low Malm permeability scenario (i.e. model run A introduced in Fig. 3), and b the high Malm permeability scenario (i.e. model run B). The geothermal Péclet number is dimensionless. Vertical exaggeration equals three
