The acoustically‐filtered, nonhydrostatic flow model formulated by M. J. Miller and R. P. Pearce in 1974 may be modified so as to remove dependence on a certain thermodynamic reference state. The modified model seems appropriate for mesoscale integrations. It implies an elliptic diagnostic equation for the height field, a satisfactory energy equation and an analogue of Ertel's potential vorticity theorem. These properties are also possessed by Miller and Pearce's original model, but in different forms (which have been obtained previously by various authors).
