Finite Element Barotropic Model for the Indian and Western Pacific Ocean Basin: Tidal Model Data Comparisons and Sensitivities

Abstract

We develop a 9.6 million node unstructured grid finite-element barotropic fully hydrodynamic model in order to understand the shallow-water dynamics of the Indian Ocean and Western Pacific Ocean basins down to sub-kilometer scale at the coast. Tidal model-data comparisons against tide gauges and a global data-assimilated model are conducted in order to identify the capabilities and limitations of our model. The average root-mean-square (RMS) discrepancies of the total free surface at coastal tide gauges is 14 cm, -3 cm smaller than the data-assimilated model. Sensitivities related to lateral boundary conditions, bathymetry, and dissipative dissipative processes are explored.
