Consistent quasi‐shallow models of the global atmosphere in non‐spherical geopotential coordinates with complete Coriolis force

A pair of dynamically consistent quasi‐shallow equation sets has recently been developed for global spherical atmospheres and oceans in spherical polar coordinates, using the standard spherical geopotential approximation. This pair is of intermediate complexity between two standard known pairs (one shallow, one deep). A surprising feature of this new pair is that the fluid is assumed to be of essentially shallow depth, yet the Coriolis force is completely represented. This is in contradistinction to the traditional shallow pair, where the Coriolis force is incompletely represented in order to achieve dynamical consistency.
