DOI: 10.1002/2017gl076075
Abstract: A new ocean evaluation metric, the crossover time, is defined as the time it takes for a numerical model to equal the performance of persistence. As an example, the average crossover time calculated using the… read more here.

DOI: 10.1016/j.ocemod.2017.08.001
Abstract: Abstract Most community ocean models that use z - or s -coordinates stagger their variables in the vertical using a Lorenz grid. Spurious short-wave baroclinic instabilities have been shown to occur on that grid by… read more here.

DOI: 10.1029/2022ms003545
Abstract: The development of any atmosphere or ocean model warrants a suite of test cases (TCs) to verify its spatial and temporal discretizations, order of accuracy, stability, reproducibility, portability, scalability, etc. In this paper, we present… read more here.

DOI: 10.1029/2024ms004383
Abstract: Water Mass Transformation (WMT) theory provides conceptual tools that in principle enable innovative analyses of numerical ocean models; in practice, however, these methods can be challenging to implement and interpret, and therefore remain under‐utilized. Our… read more here.
