Data assimilative ocean models play crucial roles in furthering the understanding, and providing forecasts of the Agulhas Current system. This study investigates the impact that assimilating sea surface temperatures (SST) combined with sea level anomalies (SLA) has on the simulated surface velocities of the Agulhas Current in a Hybrid Coordinate Ocean Model. A preliminary comparison of a free running simulation (FREE) and two assimilation experiments, (1) SLA only assimilation (ASSIMSLA) and (2) combined SLA and SST assimilation (ASSIMcombined), indicates that the impact is sensitive to the observed/simulated velocity magnitude in the Agulhas Current, while the mean velocities are overestimated compared to drifter observations.
