DCPOM project (Dennou-Club Planetary Oceanic Model project)

=======================================================================================

Target

DCPOM project designs and develops ocean and sea ice models in order to explore climates on exoplanets.

Models

• Global oceanic general circulation model for ocean planet climates (dogcm)

  • Ocean component
    • Dynamical core: hydrostatic Boussinesq equations
    • Parameterizations for sub-grid scale processes
      • Meso-scale eddy mixing
        • isopycnal diffusion scheme (Redi, 1982)
        • GM scheme based on skew flux (Gent and McWilliams, 1990; Griffies et al, 1998)
      • Convective mixing
        • convective adjustment scheme (Marotzke, 1991)
    • Numerical method
      • horizontal discretization: a spectral Eulerian method based spherical harmonics
      • vertical discretization: a finite volume method
      • time discretization
        • a LF-AM3 scheme (Shchepetkin and McWilliams, 2005) for advective process
    • a leapfrog scheme for fast wave process and vertical diffusive process, a backward Euler scheme for lateral diffusive process
  • Sea ice component
    • Thermodynamic 3 layers sea ice model based on a formulation by Winton(2000).
  • Note
    • This ocean-sea ice model can couple to an atmospheric general circulation model (DCPAM). For details, please see DCPCM project.
    • Coast lines can not be considered in the model

• Experimental models

  • Global shallow water model with a finite volume method (globalSWM-FVM)

    • The grid sysyem is triangle - hexagonal grid, and the governing equations are discretized with TRiSK proposed by Ringler et al. (2010).

  • Global shallow water model with a discontinuous Galerkin method (globalSWM-DG)

    • The model mesh is spherical triangle mesh, and the governing equation are discretized with a DG method proposed by Läuter et al. (2008).
