Abstract
HOPE is a primitive-equation model of the global ocean circulation, but may also be
used for regional studies. Prognostic variables are the three-dimensional horizontal
velocity fields, the sea-surface elevation, and the thermohaline variables. The equa-
tions are discretized on prescribed horizontal surfaces using Arakawa-E-type grids.
Two time levels are used for the integration.

A Hibler-type dynamic sea-ice model allows a prognostic calculation of sea-ice thick-
ness, compactness, and velocities. The thermodynamic growth of sea ice is calculated
with heat balance equations using simple bulk formulae. A snow layer is included.

HOPE is in particular useful for altimetry data assimilation purposes because of the
prognostic calculation of the sea-surface elevation.
