"A nonlinear 'Moist' Shallow Water model including condensation and latent heat release: Development and Applications"

The impact of condensation of water vapor and latent heat release can be important for many atmospheric dynamical processes at the Tropics but also at midlatitudes. We developed a new idealized atmospheric 2-layer Shallow Water model taking into account the dynamical effect of moisture for which the latent heat release is represented as a mass flux between two isentropic layers. This model presents correct moist properties and has the advantage to conserve a nonlinear and ageostrophic dynamics. It has been used to study the impact of latent heat release on a baroclinic life-cycle and more recently to analyze the energy transport by the midlatitude eddies within a moist stormtrack.
