Downscaling strategy
Use Global HYCOM and NCOM at the lateral boundaries to initialize and force a suite of higher resolution nested models including HYCOM (primary focus), POM and ROMS.
Modelling strategy, forcings, variables estimated and prediction range:
A set of one-way nested 3-dimensional models (hydrodynamic and coupled ecosystem) from the Atlantic to the northwest European shelf. Open boundary forcing for Atlantic Margin Model from FOAM (6h); atmospheric forcing from Met Office NWP system (1h); lateral boundary river data provided by a monthly climatology of runoff and associated loadings. Nowcasting and 5 day forecasting. HAB forecasts provided via fuzzy logic algorithms.
| Why does this project need large-scale estimates? | To provide the oceanic influence on the NW European Shelf. We use FOAM N Atlantic model data for boundary conditions. Downscaling onto northwest shelf provided through one-way nesting utilizing radiation condition for the barotropic forcing (including specification of tides) and a relaxation condition for baroclinic forcing. 3-dimensional temperature, salinity, currents and surface elevation derived from the rigid lid pressure (6h). |
| Through which Modelling/Assimilation Center? | Met Office / Mersea |
| Does the project have a verification/validation strategy which can help assess the impact of large-scale estimates? | Model outputs are routinely compared to satellite SST, in-situ moorings (MAWS, Coastal Observatory, Cefas Smartbuoy), Portsmouth-Bilboa ferry measurements. |
Project status
