HIM: The Hallberg Isopycnal ModelEntry ID: NOAA_GFDL_HIM
Abstract: The Hallberg Isopycnal Model (HIM) simulates the ocean by numerically solving the Boussinesq primitive equations in isopycnal vertical coordinates and general orthogonal horizontal coordinates. These equations are horizontally discretized on an Arakawa C-grid. There are a range of options for the physical parameterizations, from those most appropriate to highly idealized models for studies of ... geophysical fluid dynamics to a rich suite of processes appropriate for realistic ocean simulations. The thermodynamic options range from an adiabatic model with fixed density layers to a model with temperature and salinity as state variables and using a full nonlinear equation of state. The uppermost few layers may be used to describe a bulk mixed layer, including the effects of penetrating shortwave radiation. Either a split- explicit time stepping scheme or a non-split scheme may be used for the dynamics, while the time stepping may be split (and use different numbers of steps to c over the same interval) for the forcing, the thermodynamics, and for the dynamics. Most of the numerics are second order accurate in space and great care is taken in the handling of vanishing layers.
This user's manual describes how to configure and run HIM. It is short because the model is fairly simple to run. It is the author's experience that a number of people have been able to get scientifically meaningful simulations going in less than a day with about this level of guidance.
