Setting and results

• Setting
  • Primive eqaution system
  • Semi-Lagrangian transport of water vapor and cloud water and ice
  • Radiation model for the Earth's atmosphere
  • Turbulent mixing (Mellor and Yamada (1982) level 2.5)
  • Surface flux (Beljaars and Holtslag, 1991)
  • Simple land model (bucket model, subsurface heat conduction)
  • Relaxed Arakawa-Schubert cumulus parameterization (Moorthi and Suarez, 1992) with including ice phase
  • Non convective condensation (Le Treut and Li, 1991) with including ice phase
  • Convective adjustment (e.g., Manabe et al., 1965)
  • Simple cloud model (turbulent mixing, production by condensation, loss with constant lifetime, evaporation)
  • Gravity wave drag
  • Used data
    • Topography (ETOPO1), land use (Matthews, 1983, 1984, 1985)
