Abstract
Observational and numerical studies have consistently shown the im portance of latent heat release associated with frontal precipitation in the development of a Mei-Yu front. However, a systematic evaluation of pre cipitation parameterization in the simulation of a Mei-Yu front has been rare in the literature. In order to enhance our understanding on precipita tion parameterization of Mei-Yu fronts, this study conducts numerical ex periments to evaluate the performance of subgrid-scale cumulus schemes and resolvable-scale microphysics schemes to simulate the Mei-Yu frontal system on 4-5 June 1998 at grid resolutions of 45 km and 15 km, using the Penn State/NCAR mesoscale model MM5. Principal findings are summa rized here.
