P27 - MONCOZE
Project name, acronym
MONCOZE is MONitoring the COastal Zone Ecosystem.
Domain
The model covers the North Sea with 4 km resolution (conformal mapping grid) approximately from 50N to 63N and from 5W to 10E.
Objectives
The objective is to study the currents and ecosystem in the North Sea.
Type:
Hindcast studies, research.
Customers:
Research, Meteorological agencies (met.no). society at large.
Funding aspects:
This project has been set up by the MONCOZE project funded by The Research Council of Norway (RCN).
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 TOPAZ. 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 monitoring and prediction system is driven by external inputs, atmospheric forcing fields from ECMWF.
| Why does this project need large-scale estimates? | The North Atlantic Water inflow 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? | TOPAZ is provided by the Mohn-Sverdrup Center at the Nansen Center, Bergen. |
Project status
The project is completed. A hindcast study for the years 1997-1998 has led to 3 peer reviewed scientific publications (Winther & Evensen 2006, Winther et al. 2006, Winther & Johannessen 2006), the model has been run in real-time for a test period and its domain is now covered be the larger CONMAN system. The model may be run with a coupled ecosystem model at a later stage.
