Key Equations

$$\frac{\partial T}{\partial t} + \mathbf{u} \cdot \nabla T = \kappa_T \nabla^2 T + \frac{Q}{\rho c_p h} \qquad \frac{\partial S}{\partial t} + \mathbf{u} \cdot \nabla S = \kappa_S \nabla^2 S + \frac{S_0(E - P - R)}{h}$$
$$\theta = T - \int_0^p \Gamma(S, T, p') \, dp' \quad \text{where} \quad \Gamma = \frac{\alpha T}{\rho c_p} \approx 0.1\text{--}0.2 \text{ °C per 1000 dbar}$$
$$\frac{\partial S}{\partial t} \bigg|_{\text{surface}} \approx \frac{S_0 (E - P)}{h_{\text{mix}}}$$
$$\theta_{\text{mix}} = f \cdot \theta_1 + (1-f) \cdot \theta_2 \qquad S_{\text{mix}} = f \cdot S_1 + (1-f) \cdot S_2$$
