Assimilation Modeling of Coastal Transition Zone Data and Continental Slope Flow Fields

Abstract

Linear analysis of Coastal Transition Zone jet profiles indicates that 150 km and less wavelength instabilities are predominantly barotropic, while for wavelengths 200 km and greater the fastest growing modes have nearly equal contributions from barotropic and baroclinic energy conversions. Physical mechanisms for retention and accumulation of biomass at fronts have been identified and explored. Results of intermediate model (IM) studies applied to the shallow-water equations show that time the IM equations may be solved numerically with appropriate boundary conditions to correctly represent ageostrophic coastally-trapped wave dynamics.
