This paper is supposed to serve as an introduction to a model configuration, grid resolution hierarchy, and to datasets for use by the community (lines 231–232). The model hierarchy (NeverWorld2) is reasonably well-described. It consists of a two-hemisphere basin with a southern reentrant channel realized using the adiabatic layered mode of MOM6. The idealized setup is similar to a number of previous iterations on the idea, although its use of adiabatic layer coordinates and analytically specified topography make the setup well suited for its intended use, which is to understand mesoscale eddy parameterizations and the impact of resolution on mesoscale eddy dynamics. To this end, the model hierarchy consists of four resolutions ranging in powers of two from 1/4º to 1/32º. The bulk of the manuscript is devoted to model description and comparison of the solutions at different resolutions.
The NeverWorld2 model hierarchy promises to be a useful tool for understanding mesoscale dynamics and I appreciate that the authors are releasing and documenting it. The manuscript is well-written and approachable overall, although there are some points that could be clarified and a some changes (discussed below) that would make the paper more useful and understandable. Perhaps the papers most significant shortcoming as an “introduction to datasets” is that the datasets themselves are not actually described, nor is a useable link or pointer to them provided to the reader. There is a statement in the “code and data availability” section that the dataset will be publicly available via Open Storage Network, but there’s no indication of when or how they can be accessed. Information on the contents of the datasets beyond that they’ll include “initial conditions and restart files” would also be useful. For example, it would be nice to know if the available data will also include mean fields, derived quantities (e.g., EKE, fluxes), and snapshots.
Other than the lack of discussion of datasets, most of my concerns relate to claims/demonstrations of convergence with resolution (see major comments below). I think the paper is quite publishable if these issues can be addressed. My sense is that the required revisions lie in the grey area between “major” and “minor”—I selected “major” but would not argue if the editor dropped it to “minor.”
There several attempts to argue that the 1/32º version is converged or approaching convergence, but a number are confusing or not convincing.
Minor issues (garmmar, typos, etc)
