A primitive equation model recently developed by the author is used to confirm previously obtained quasi geostrophic results concerning moist baroclinic instability in an Eady framework. Perturbation development is then followed in the non-linear regime and life-cycle studies are performed of baroclinic cyclones modified by release of latent heat in various environmental conditions. Non-adiabatic effects are represented using a small value of static stability for upward moving, saturated air, and a larger one for descending motion.
