Thank you for revising your manuscript in accordance with the provided comments.

In order to proceed it is required that the author submit "a marked-up manuscript version (track changes in Word, latexdiff in LaTeX) converted into a *.pdf must be submitted, uploaded as a supplement to the author comment." This is typically included within the Author's response to the editor.

Further, I believe it would be valuable if some comment could be included in the manuscript with regard to the impact of increased order of accuracy (analogous to a one sentence version of your response 7c). Something analogous to:

"The conclusions of this linear analysis are not qualitatively impacted by increasing the order-of-accuracy, but moving to high-order improves errors in the intermediate wavelengths and confines errors to the shortest resolved horizontal scale."

Also it would be useful to have a comment in the introduction on the fact that your analysis does not account for explicit diffusion terms, which are frequently included in operational models. Perhaps as part of the paragraph beginning "The purpose of this paper..."

In the discussion of the CD-grid, I also think it would be valuable to point out that FV3 uses a fourth-order discretization (or a high-order discretization). Or identify in the sentence "In this section, we examine the performance of the CD grid as inferred from a normal-mode analysis" that you are analyzing the CD-grid in the case of a second-order discretization.

Thank you for considering these suggestions. Please let me know if you would like to discuss.

Thank you for taking the time to address all reviewer comments. I believe the updated manuscript is now acceptable for publication.
