My long-term goal is improving 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 progressively distorts 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. Understanding the errors and modeling neglected processes are critical to improving prognostic skill when small-scale nonlinear errors can accumulate over time.
