BAPE (Boussinesq Approximated Primitive Equation model) is a multilevel primitive equation model for a baroclinic fluid in a double periodic domain. It can be applied for studies on baroclinic instability, cyclogenesis and frontogenesis.

Baroclinic instability simulations with BAPE for various Rossby numbers. The black isolines show isobars and the coloured shadings the temperature gradient at the lowest model level and at the time of maximum wave energy.
