SUMMARY:Development of the Global High-Resolution Wave-Tide-Circulation Co
 upled Ocean Model and its Operational Application
DESCRIPTION:Minisymposium\nClimate and Weather\n\nDevelopment of the Globa
 l High-Resolution Wave-Tide-Circulation Coupled Ocean Model and its Operat
 ional Application\n\nXiao, Qiao, Yin, Wang\n\nA global 1/10° wave-tide
 -circulation coupled ocean model (FIOCOM) is developed and applied in
  operational forecasting. The newly-developed FIOCOM consists of three par
 ts, they are ocean general circulation model (MOM5), sea-ice model (SIS) a
 nd wave model (MASNUM). The horizontal resolution is 1/10°, vertically
  it has 54 vertical levels with the finest vertical resolution of 2m.
  Wave-circulation coupled theory is applied in which non-breaking wav
 e induced mixing is incorporated, tide is also coupled into this model by 
 introducing 8 tidal potentials. Its unique feature is that the global circ
 ulation, mesoscale eddy field, improved upper layer ocean simulation,
  internal tide and global barotropic tide are resolved in this single syst
 em. The Ensemble Adjustment Kalman Filter (EAKF) data assimilati
 on is applied. The EAKF can assimilate Argo profile, SST, and ADT obs
 ervation data which can generate reasonably accurate initial condition for
  the global ocean forecasting. The design for a better load balance during
  the parallel calculation based on MPI in the wave model components a
 nd data assimilation is name as irregular rectangle partitioning. Comprehe
 nsive validations are conducted using various observation data such as TOG
 A, AVHRR, etc. The long-term validations show that the FIOCOM have reasona
 ble accuracy compared with the existing global high resolution ocean forec
 asting system.
