Abstract: A two-dimensional,slab-symmetry,anelastic and non-hydrostatic cirrus model was developed in which a bulk-microphysical Parameterization of the moist Processes among Water vapor,cloud water,cloud ice crysstals,snow and graupels was included The model was very flexible for the:a女e of the changible domain,the stretched grid length and its applicability for various cold clouds.With the model,an idealized case of cirrus convective cell was simulated and compared with obscrvations.It was (4×10-3s-1).The results were analysed and compared with observations.It was indicated that the macro-structures (in-cloud updrafts,multi-core structure,cloud life and so on) and micro-characteristics (ice crystal concentration and supercool liquid water distribution) of the modeling cirrus were consistent with observations.
