Insertion, Validation, and Application of Barotropic and Baroclinic Tides in 1/12 and 1/25 Degree Global HYCOM
Abstract
The partnership will utilize global HYCOM, run at horizontal resolutions of 1/12 deg and 1/25 deg, with barotropic and baroclinic tides inserted. Thus far, the global NRL simulation is a forward simulation; that is, a simulation without data assimilation. The NRL group is working to develop accurate data-assimilative models with tides. The contribution of the University of Michigan (UM) group to the assimilation effort will be to recruit a graduate student to work with Arbic and NRL collaborators on this topic. Since the goal of operational models is high accuracy, we have endeavored to create forward models which achieve a high level of accuracy in the tides before the data assimilation is inserted. In this way, the data-assimilative models build upon an accurate foundation laid by the forward models. Our research will continue to focus on improving the forward tidal simulations, with an added new focus on building up a new capacity for data-assimilative simulations which include tides. In addition, Arbic and the UM team will collaborate with both NRL and FSU on the most efficient way to store HYCOM output with tides in the FSU-based data server
