Multi-Layer Mixed-Layer Ocean Model

  • A multi-layer mixed-layer ocean (MLO) model with global coverage was developed when I worked at the Climate and Radiation Branch, NASA Goddard Space Flighty Center. The core of this model is a 1-D MLO based on the work of Gaspar (J. Phys. Ocean., 1988). The 1-D model can be used independent of the global model.
  • This model has no horizaontal advection. Flux corrections for heat and salinity are derived from training to represent the transport of heat and water mass by oceanc currents.
  • Within the mixed layer, temperature and salinity are prognostics. mixed-layer depth is prognostics when entrainment occurs, and is diagnostics when mixed layer shoals. In layers below the mixed layer, vertical diffusion, convective adjustment and solar radiation pentration are included. In addition, temperature and salinity at layers below the mixed layer are also relaxed to observed climatologies in a 10-year time scale.

    • The entire model code with boundary and initial conditions, and running scripts can be obtained by anonymous ftp . The core of the 1-D model can be viewed here , together with a readme file. A Power Point presentation may help you understand better the model.
