Description
Summary:In Part I of this paper series, the dynamic equations, numerical solution procedures and the parameterizations of subgrid-scale and PBL turbulence of the Advanced Regional Prediction System (ARPS) were described. The dynamic and numerical framework of the model was verified using idealized and real mountain flow cases and an idealized density current. In this Part II, we present the treatment of other physics processes and the related verifications. The PBL and surface layer parameterization, the soil model and the atmospheric radiation packages are tested in a fully coupled mode to simulate the development and evolution of the PBL over a 48-hour period, using the Wangara day-33 data. A good agreement is found between the simulated and observed PBL evolution, at both day and night times. The model is used to simulate a 3-D supercell storms that is well documented in previous literature. The results show that considerable errors can result from the use of conventional non-conservative advection schemes; the ice microphysics option coupled with a monotonic advection scheme yields the most realistic simulation with better prediction of precipitation.
