  1. LASG Model: FGOALS-SAMIL(Flexible Global Ocean-Atmosphere-Land System/Spectral Atmosphere Model) Guoxiong Wu, Zaizhi Wang * State Key Lab of Atmospheric Sciences and Geophysical Fluid Dynamics (LASG)Institute of Atmospheric Physics (IAP)Chinese Academy of Sciences (CAS) * Affiliation: Guangzhou Institute of Tropical & Marine Meteorology, CMA

  2. Content • Group introduction • Model highlights • Summary

  3. Group introduction • Guoxiong Wu • Yimin Liu • Zaizhi Wang • Xiaoyun Liang* • Tianjun Zhou • Qing Bao • Liang Guo * Affiliation: National Climate Center, CMA

  4. Model highlights • Spectral Atmos. Model • Resolution flexible(R15, R42, L9, L18, L26) • Program standardized(can run on SGI, IBM, Pc cluster) • Parallelized (OMP, MPI) and modularized( plug-in and out) • Dynamics • Standard Atmosphere Subtraction • Sigma-coordinate /Hybrid-coordinate

  5. Model highlights • Physics • k-distribution radiation scheme(UKMO scheme) • Slingo cloud parameterization scheme (statistical cloud scheme, climate cloud scheme) • Manable convective parameterization (Zhang McFarlance schem, ECHAM scheme) • SSiB (CLM) • Coupled to FGOALS • Fully coupled climate system

  6. Ocean (LICOM) Atmos (SAMIL) CSM Coupler Land (NCAR CLM) Sea Ice (NCAR CSIM4) FGOALS

  7. East Asian monsoon precipitation simulation SAMIL CMAP

  8. Summary • SAMIL can be used in the dynamic researches on large-scale mountain, the role of surface sensible heating, condensation heating, etc. • SAMIL can also be used in the researches on monsoon evolution, subtropical high, etc. • FGOALS can run stably for more than 200 yrs, and will complete CMIP required experiments.
