ABSTRACT

A modeling effort has spun up at UCSC to better understand the dynamics and interdisciplinary applications of the California coastal circulation. We apply the ROMS model in the usual sort of configuration, driven by COAMPS forcing at the surface and boundary conditions provided by the ECCO project. This talk will focus on three unique aspects of our effort. The sensitivity of several metrics characterizing the coastal circulation to local and nonlocal forcing are examined using the newly developed ROMS adjoint model. We've implemented a 4-dimensional variational approach to assimilating SST, SSH and hydrographic information within the CCS. I will close with a discussion of the application of this model to understand the time-mean and seasonally varying statistics for nearshore biological population connectivity and alongshore dispersion by coastal currents.
