Operational ocean forecasting and short- to medium range coupled prediction at the Bureau of Meteorology

Gary Brassington
Australian Bureau of Meteorology


In this talk I will give a short overview of the operational ocean forecasting systems that emerged from the Global Ocean Data Assimilation Experiment (GODAE) as well as the Bureau's BLUElink OceanMAPS system. A summary of the performance of the current system, particularly in relation to SST and sea surface height other relevant metrics will be given. The BLUElink Coupled Limited Area Model is our developmental system that has been trialed with TCLAPS and now ACCESS-TC for tropical cyclone prediction and recent extensions to more general coupled prediction. Some results from this system and other examples of coupled relationships will be presented as well as the benefits to ocean prediction. Should NWP consider a slab, coarse ocean or an eddy ocean and other debatable topics will be raised as the motivation for a joint WGNE-GODAE workshop on short- to medium-range coupled prediction.
