HOW THE PROJECT WORKS:OCEAN MODELLING
SYSTEM
Ocean model
In recent years, scientists at CSIRO and the Bureau of Meteorology
have developed and then refined the Australian Community Ocean
Model (ACOM) with three versions of this model having been
developed.
The latest version of this model is called OFAM - Ocean Forecasting
Australia Model). It is based on the Modular Ocean Model (MOM4)
code developed by the Geophysical Fluid Dynamics Laboratory
(GFDL) in the United States, will be the platform for the
short-range forecasting system."
The model will resolve eddies in the "Region" (90E-180E,
60S-10N), be eddy-permitting in the remaining parts of the
Indo-Pacific Oceans and coarser resolution elsewhere (e.g.
North Atlantic).
Operational Ocean Forecast System
The Bureau of Meteorology Research Centre and CSIRO will
develop an enhanced ocean model and data assimilation system
for operational delivery of ocean forecasts. Available in
situ and satellite observations from the data server and regional
analyses will be assimilated directly into the ocean model
using an advanced assimilation technique to provide improved
short-range model predictions with forecast skill of up to
4-6 days. The surface forcing will be provided by the Bureau
of Meteorology’s operational numerical weather prediction
systems (global, regional and, as appropriate, local).
Ocean forecasts will be released twice weekly, and will be
updated to include the latest changes in the weather systems
and wind systems, particularly extreme conditions such as
from tropical cyclones.
Success of the system depends on successful development,
testing and fine-tuning of the prototype ocean model and assimilation
system.
