Hydrostatic vs. Non-Hydrostatic Hydrostatic models assume hydrostatic equilibrium Valid for most synoptic and global systems and some mesoscalephenomena Non-hydrostatic models include equations for verticalmotions that hydrostatic models lack Most grid-point models and all spectral models inoperation are hydrostatic Many mesoscale models are non-hydrostatic Non-hydrostatic processes and effects becomeimportant when length of a feature is approximatelyequal to its height Typically features 10 km and less in size
