For the Earth’s mantle, the typical average properties from which the Rayleigh number is constructed are ρ ≈ 4000kg/m3, g = 10m/s2, α = 3×10−5K−1, ∆T ≈ 3000K, d = 2900km, µ = 1022Pa s (dominated by the lower man-tle), and κ = 10−6m2/s [see Schubert et al., 2001]. Taken together these lead to a Rayleigh
