Abstract:

The long-term goal of my research is to develop, verify, and apply numerical ocean prediction models to eastern boundary coastal regions to improve our scientific understanding of the structure and dynamics of such regions. The broad objective of this research is to aid in the development of a reliable modeling capability for eastern boundary current regions. My specific objective is to carry out and extensively verify several DieCAST model simulations of the annual cycle in the California Current. I also wish to evaluate and apply digital filter initialization DFI as a diagnostic tool in numerical ocean prediction. I intend to carry out increasingly complex numerical simulations of the California Current using the DieCAST regional model. I will then verify the simulations against ONRs extensive eastern boundary current EBC data sets. I also intend to evaluate iterative versions of DFI as a diagnostic tool for ocean analysis, and then apply the method to several quasi-synoptic hydrographic data sets from the California Current and the Alboran Sea. Results from the California Current will be compared with those obtained using the iterated geostrophic method IGM, Allen 1993, and the results from the Alboran Sea will be verified using direct measurements of the vertical velocity determined by quasi-isobaric RAFOS floats.
