| Summary: | 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. |
