Abstract:

My long-term goal is improving our understanding of interactions between sub-grid scale models and numerical errors, which affect simulation skill for physical and biological processes in estuaries and coastal ocean environments. For prognostic simulations, slow accumulation of truncation-level errors will progressively distort model results. Present sub-grid scale models selectively address certain processes e.g. turbulence while neglecting other processes e.g. small-scale internal waves, particulate nature of algae. As small-scale nonlinear errors can accumulate over time, understanding the errors and modeling the neglected processes are critical issues in improving our prognostic skill.
