Abstract:

The long-term goal of this project is to improve our capability to predict the inherent spatial and temporal variability near the Philippine Straits, and thus contribute to the development of reliable prediction systems. The primary focus is to provide a comprehensive understanding of the remote and local factors that control the meso- and submesoscale features in and around the Philippine Archipelago Straits. The main objectives are to explore the effects on the Philippine Straits of remote forcing from the equatorial waveguides, throughflows, and adjacent seas mesoscale dynamics to estimate the effects of local winds in generating meso- and submesoscale variability to quantify the role of barotropic tidal forcing in promoting side wall eddies and internal tides to study the role of abrupt changes in bathymetry in generating submesoscale variability and to investigate the impact of variational data assimilation on the simulation and predictability of the meso- and submesoscale circulation features.
