Arctic and Nordic Seas
P20 - Eddy resolving HYCOM model of the Nordic Seas (NORDIC)
Domain
The model covers the Nordic Seas with 4 km resolution (conformal mapping grid) Approximately from 55N to 83N and from 30W to 20E.
Objectives
Hindcast studies, research.
The objective is to study the mesoscale currents in the Nordic Seas.
Customers:
Research, society at large.
Funding aspects:
This project is funded by The Research Council of Norway (RCN) through the Ocean Weather and Ecosystem project of the FRINAT programme.
Downscaling strategy
One-way and off-line nesting offer sufficient flexibility for operating the nested model.
This is a HYCOM-to-HYCOM downscaling, the outer model is TOPAZ3. The downscaling method is from that of Browning and Kreiss (1982, 1986) with bilinear interpolation to the nested rotated horizontal grid. The frequency of nesting conditions is 6-hourly. Astronomical tides are added.
The system is driven by external inputs, atmospheric forcing fields from ECMWF.
| Why does this project need large-scale estimates? | The inflow of North Atlantic Water and Arctic Waters needs to be correctly represented. High quality lateral boundary conditions of ocean parameter are absolutely vital. |
| Strategy for validation of boundary conditions? | The incoming fluxes, kinetic energy and water mass properties are monitored in the nested model and compared to available observations and to the outer model. |
| What particular GODAE estimates does this project use, how often, etc.? | The project uses TOPAZ boundary conditions for 3D ocean parameters. The frequency of nesting files is 6-hours. Tides are included. |
| Through which Modelling/Assimilation Center? | The Mohn-Sverdrup Center at the Nansen Center, Bergen. |
Project status
The model is in development phase.
