Microphysics in Multi-scale Modeling System with Unified Physics (Invited)

Recently, several major improvements of ice microphysical processes (or schemes) have been developed for cloud-resolving models (Goddard Cumulus Ensemble, GCE, model), regional scale (Weather Research and Forecast, WRF) model and MMF. These improvements include an improved 3-ICE (cloud ice, snow and graupel) scheme (Lang et al. 2011); a 4-ICE (cloud ice, snow, graupel and hail; Lang et al. 2013) scheme and a spectral bin microphysics scheme and two different two-moment microphysics schemes. These models have improved the radiative processes and their interactions with cloud and aerosol. The performance of these schemes has been evaluated by using observational data from TRMM and major field campaigns. In this talk, we will present high-resolution GCE, WRF and MMF model simulations and compare the model results with observations [i.e., Typhoon (Morakot 2009 - an updated simulations), Anvil and Aerosol (AMMA 2006); MCSs (MC3E; 2010; diurnal variation) and CloudSat/TRMM]. In addition, the main issues of the microphysics schemes in high-resolution (1-6 km grid spacing) numerical models will be discussed.
