Project “BLUElink”
• A partnership between:• CSIRO• Australian Bureau of
Meteorology (BoM)• Royal Australian Navy
(RAN)
Australia!
(Nature cover)
High-level objectives of BLUElink
• To develop an ocean forecasting capability in the Bureau of Meteorology
• To enable the RAN to forecast local ocean and atmospheric conditions
Key elements
• “Real-time” data availability (“nowcasts”)
• Archived ocean hindcasts, based on global modelling
• Ocean forecasts, based on global model
• Automated model nesting

Ocean Nowcasting
A daily-updated nowcast of the 3-d temperature, salinity and current fields for the Asian-Australian region based on in situ (Argo and XBT) and satellite (altimeter, SST) data
The Global Model
Ocean Forecasting Australia Model
Based on MOM4
Provides an archive (1992 on) and operational 3-10 day forecasts
