This Project Grant from the National Science Foundation Division of Ocean Sciences, under the Geosciences federal grant program (CFDA 47.050), provides $438,368 to Brown University to create a new theoretical framework for improving eddy parameterizations in numerical models from August 1, 2022 to July 31, 2025. The framework constitutes principles linking physical meaning to parameterization form, allowing for cross-evaluation of existing or proposed parameterizations from first principles. Significant software packages to result include symbolic algebra software for implementing eddy parameterizations in any model coordinate system or discretization, and numerical code for diagnosing errors in model implementation. The explicit, stochastic, coordinate-independent framework will incorporate rigorous definitions for filtering and averaging operations, a flexible stochastic modeling approach, and coordinate-independent representations to express parameterizations independent of model geometry. This work aims to clarify links between parameterization forms and conserved properties, speed identification of discretization errors, uniquely identify advective and diffusive flux components, and account for impacts of observed eddy trajectory behavior.
