Formulation of a non-hydrostatic model for moist convection in theMartian atmosphere

Abstract

Formulation of a non-hydrostatic model for moist convection associated with condensation of major atmospheric component in the Martian atmosphere is examined. When the supersaturation of carbon dioxide is small or the time scal of condensation is longer than that of sound wave, a modified quasi-compressible system in which a mass source term associated with condensation is introduced in the continuity equation can be adapted for the Martian atmospheric moist convection. We develop a 2D non-hydrostatic model based on the formulation of modified quasi-compressible system and investigate flow patterns associated with the Martian atmospheric moist convection with steady thermal forcing.
