Python Ocean Model 2.0 (pyOM2)
Contents
Introduction
pyOM2 is a numerical circulation ocean model powered by Python. Features are:
* Cartesian or pseudo-spherical coordinate systems
* Hydrostatic or non-hydrostatic configurations
* energetically consistent parameterisations
* Fortran and Python front end
* Graphical User Interface
* fully parallelized using MPI
Idealized and realistic configurations are simple and easy to configure and to integrate. Fortran and a Python version are based on the identical Fortran90 core code. Several idealized and realistic examples are preconfigured and can be easily chosen and modified using two alternative configuration methods based on Fortran90 or Python.
