Toward Multiscale Simulation of Moist Flows with Soundproof Equations

摘要: AbstractThis paper discusses the incorporation of phase changes water substance that accompany moist atmospheric flows into all-scale model based on soundproof equations. A specific issue involves developing a theoretical basis and practical implementation to include pressure perturbations associated with circulations, from small scale global, representations thermodynamics. In small-scale modeling using equations, are obtained elliptic solver typically excluded This argues in larger-scale flows, at least hydrostatic component perturbation needs be included because variation synoptic weather systems may affect thermodynamics way comparable temperature variations. As an illustration, two idealized test problems considered: thermal rising stratified environment mois...
