Coastal Seas Modelling
The Proudman Oceanographic Laboratory Coastal Ocean Modelling System (POLCOMS) was developed at the Proudman Oceanographic Laboratory, and run operationally at the Met Office since June 2000. It is run daily in three nested configurations on the North West European continental shelves, nested inside North Atlantic FOAM deep ocean model, including one configuration with a full ecosystem model, and in the Persian Gulf.
|Domain||Resolution and Coverage||Vertical Levels||Operational Runs|
|Atlantic Margin Model||12 km, 40N-65N, 20W-13E
||34||Daily forecast to five days ahead|
|Medium Resolution Continental Shelf||6 km, 48N-62N, 12W-13E
||20||Daily forecast to five days ahead|
|European Regional Seas Ecosystem
Model (inside MRCS)
|6 km 48N-62N, 12W-13E||20||Daily forecast to five days ahead|
|Irish Sea||1.8 km, 51N-56N, 7.0W-2.7W||20||Daily forecast to two days ahead|
|Persian Gulf||12 km||20||Daily forecast to five days ahead|
The daily runs forecast ocean currents, salinity and temperature driven by the combination of wind, tides and ocean density contrasts, while biological parameters also forecast by the ERSEM ecosystem model. At higher resolutions, the models are able to resolve ocean eddies and intricate coastal features.
The shelf-seas modelling system is relocatable, allowing configurations to be set up for any shelf-seas region.
