Flow through the Straits of the Philippine Archipelago Simulated by Global HYCOM and EAS NCOM

Abstract

We are collaborating with other DRI participants to better evaluate and understand the dynamics seen in observations and model results within the Philippine Archipelago, a strategic region with numerous straits. The model results come from the .08 deg and .04 deg global HYbrid Coordinate Ocean Model (HYCOM) and .088 deg East Asian Seas (EAS) Navy Coastal Ocean Model (NCOM) nested in global NCOM, the .04 deg global HYCOM and some finer nests starting in FY09, the others from the outset. Objectives of our DRI participation are (1) high resolution simulations (with and without tides; with and without data assimilation) that provide a larger scale context for the observations, (2) model-data comparisons with the measurements, (3) studies of observational representativeness in measuring transports through straits, (4) investigation of non-tidal and tidal (barotropic and internal) influences on specific sub-regions of interest, especially where measurements are available, and (5) to provide boundary conditions for nested models.
