Abstract:
Recently, several major improvements of ice microphysical processes (or schemes) have been developed for cloud-resolving models (Goddard Cumulus Ensemble, GCE, model) and regional scale (Nasa-Unified Weather Research and Forecasting, NU-WRF) models. These improvements include an improved 3-ICE (cloud ice, snow and graupel) scheme (Lang et al. 2010); 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.

The performance of these schemes has been evaluated by using observational data from GPM major field campaigns. In this talk, we will present high-resolution GCE and WRF model simulations and compare the model results with observations [i.e., MCSs (MC3E and IFloodS) and snow events (GCPEx and C3VP)]. In addition, the main issues of the microphysics schemes in high-resolution (1-6 km grid spacing) numerical models will be discussed.
