A Comprehensive Radiation Scheme for Numerical Weather Prediction Models with Potential Applications in Climate Simulations

摘要: Abstract A comprehensive scheme for the parameterization of radiative transfer in numerical weather Prediction (NWP) models has been developed. The is based on solution δ-two-stream version equation incorporating effects scattering, absorption, and emission by cloud droplets, aerosols, gases each part spectrum. An extremely flexible treatment clouds obtained allowing partial cover any model layer relating optical properties to liquid water content. latter quantity may either be a prognostic or diagnostic variable host specified priori depending type, height, similar criteria. overlapping layers realistic assumptions, but different approach requires only minor modifications code. tested extensively framework intercomparison radiation codes climate (ICRCCM, WMO 1984, 1990).
