Boundary Conditions in the Pacific West Coast Princeton Ocean Model of CoBALT
Abstract
The boundary conditions (BCs) implemented in the Pacific West Coast (PWC) version of the Princeton Ocean Model (POM) as developed at the Naval Research Laboratory (NRL) are described. BCs for the barotropic velocities along the open boundaries are a Flather form for the normal component and an advective form for the tangential component with matching to externally supplied transports. Baroclinic velocities use a radiational BC for the normal component, and an advectional BC for the tangential component. Sea surface height, temperature, and salinity use radiational or advective BCs. Simple relaxation techniques are used for the assimilation of sea surface temperature (SST) and sea surface salinity (SSS). The interior state of the ocean is maintained by relaxation to a monthly climatology. A zero gradient boundary condition is applied for the vertical velocity, a clamped condition is applied to the turbulent kinetic energy and turbulent length scale. The explicit treatment of these BCs is given here to serve as a reference for PWC POM users.
