什么是 Thermal boundary layer, thermal lithosphere？

又称： thermal boundary layer · thermal lithosphere

Definition 10.15 University Earth and Space Sciences — Year 1 · 第 10 章 — The Earth’s Heat Budget

In a convecting fluid, a thermal boundary layer is a layer along a boundary across which heat passes by conduction and the temperature changes from that of the boundary to that of the well-mixed interior. The thermal lithosphere is the upper thermal boundary layer of the mantle: the outer shell of the Earth from the surface down to the depth where the conductive geotherm meets the mantle adiabat.

Isotherms in a cooling oceanic plate: a half-space initially at 1350 C, cooled from its surface, with = 10-6\, m2\, s-1. Every isotherm deepens as the square root of age; the shaded layer above the 1200 C isotherm is the thermal lithosphere. Arrows are schematic. — Isotherms in a cooling oceanic plate: a half-space initially at $1350{}^{\circ}\mathrm{C}$ , cooled from its surface, with $\kappa = 10^{-6}\,\mathrm{m}^{2}\,\mathrm{s}^{-1}$ . Every isotherm deepens as the square root of age; the shaded layer above the $1200{}^{\circ}\mathrm{C}$ isotherm is the thermal lithosphere. Arrows are schematic.
