The model equations are the layer-integrated vector-invariant form of the hydrostatic primitive equations (either Boussinesq or non-Boussinesq).
We present the equations starting from the hydrostatic Boussinesq equation in height coordinates and progress through vector-invariant and general-coordinate equations to the final equations used in the vertical Lagrangian algorithm, taken from :cite:`Adcroft2019` and :cite:`Griffies_Adcroft_Hallberg2020`.
