Web30 de jul. de 2024 · Near the bottom of the convection zone, T0(Rc.z. ) ≈ 2.3 × 106 K. Near the surface, T0(R ⊙) / T0(Rc.z. ) ≈ 10 − 3, which vanishes to a good approximation. The convection-zone radius Rc.z. = R ⊙ − Hc.z. , where Hc.z. ≈ 200 Mm is the convection-zone depth, and R ⊙ ≈ 696 Mm is the solar radius ( Table 1 ). Therefore, WebOn Earth, the Rayleigh number for convection within Earth's mantle is estimated to be of order 10 7, which indicates vigorous convection. This value corresponds to whole mantle convection (i.e. convection extending from the Earth's surface to the border with the core ). WebFirst, the timescale of deep convection in the ocean is sufficiently long that it may be modified by the Earth’s rotation; second, the convective process is localized in space so that vertical buoyancy transfer by upright, non-hydrostatic convection can give way to slantwise transfer by baroclinic instability in balanced, geostrophic motion ... granular weed killer without fertilizer
