weak restoring towards observation-based estimates of sea-surface
temperature and sea-surface salinity), whereas in forecast mode atmospheric
forecasts from the Bureau of Meteorology’s NWP system will be used as
surface forcing for OFAM. This first experiment will also provide
preliminary but important information about the statistical behaviour of the
system (the box labelled “Diagnostics of Assimilation” in Fig. 5).
The next step will be the operational implementation of the forecasting
system at the Australian Bureau of Meteorology. Observations received in
near-real time from satellites (altimetry and SST) and in situ platforms such
as Argo floats will be analysed and ingested daily and into the forecasting
system. Short-range forecasts will be issued twice a week.
Future developments beyond the timescale of the current project will
focus on an improved data assimilation system (e.g. Ensemble Kalman
Filter) and on the implementation of a sea-ice model.
