= Mantle thermal budget
{title2=$C_m\dot{\overline T}=H_m+Q_{\rm cmb}-Q_m$}
An <energy balance> for heat stored in the <mantle>. Here $C_m$ is its effective <heat capacity>, $H_m$ internally generated radioactive power, $Q_{\rm cmb}$ power entering across the <core-mantle boundary> and $Q_m$ power leaving the mantle. The sign of the right-hand side determines warming or <secular cooling> in this reduced model. Different reservoirs and <latent heat> may require additional terms. Surface heat loss includes crustal contributions and should not be substituted for $Q_m$ without specifying the partition.
