Cloud Radiative and Microphysical Processes

Convective systems affect vertical heat and water vapor distributions through radiative and cloud microphysical processes. Due to fine spatial resolution, cloudresolving models resolve individual cloud and simulate cloud radiative and microphysical processes through solar and IR radiative parameterization and prognostic cloud microphysics parameterization. Cloud microphysical processes include vapor condensation and deposition, autoconversion, evaporation, collection, accretion, riming, and melting. Cloud-radiation interaction processes can be simulated by solar and IR radiative parameterization coupling with cloud single scattering albedo and asymmetry factor associated with cloud hydrometeor mixing ratios. In this chapter, radiative and cloud microphysical processes associated with the development of tropical convection are intensively discussed based on Li et al. (1999, 2002a,b, 2005), Sui and Li (2005), Li (2006), Gao et al. (2006a,b), and Cui et al. (2007).
