P5 - Mohn-Sverdrup Center South China Sea HYCOM (MSC-SCS)
South China Sea - Weekly average of temperature and velocity field 1995/05/1 Domain
The model covers the South China Sea with 12 km resolution (conformal mapping grid) Approximately from 8°S to 24°N and from 100°E to 130°E.
Objectives
Real-time monitoring and prediction system, hindcast studies, research. The objective is to forecast the currents in the South China Sea.
Customers:
Research, oil & gas industry (Exxon Mobil). society at large.
Funding aspect:
This project has been set up by an Ocean Numerics industry project funded by Exxon Mobil. It is being transferred to the Nansen-Zhu Center in Beijing.
Downscaling strategy
One-way and off-line nesting offer sufficient flexibility for operating the nested model.
HYCOM-to-HYCOM downscaling, the outer model is a Pacific Ocean HYCOM model of half a degree. 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 interactions with the Pacific Ocean need 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 has produced its own boundary conditions for 3D ocean parameters. The frequency of nesting files is 6-hours. Tides are included. |
| Through which Modelling/Assimilation Center? | BCs are provided by the Mohn-Sverdrup Center at the Nansen Center, Bergen. |
Project status
A 20 years hindcast study has been completed and validated and is owned by Exxon Mobil. The system will be used by the Nansen-Zhu Center in Beijing.
