Dynamical Filtering Highlights the Seasonality of Surface-Balanced Motions at Diurnal Scales in the Eastern Boundary Currents

Round 1

Reviewer 1 Report

This study is to investigate the the Eastern Boundary Currents during the winter and summer months using a high-resolution global simulation. The slmulation conducted by them presented that the dynamical filter that separates both classes of motion can provide more accurate estimation of the vertical exchanges of any tracers at any vertical level in the water column. Few minor comments need further explanation as stated below:

1         The literature review section should be as comprehensive as possible, mainly discussing the innovations and deficiencies of previous studies, as well as the relevance of this paper.

2         The figure 1 needs further optimization, is it possible to indicate the specific latitude and longitude of the quadrilateral area?

3         The conclusion section suggests listing the important conclusions one by one

Reviewer 2 Report

Dear Authors,

your manuscript sheds light on the internationally important issue. Such studies of ocean physics contribute to the comprehensiveness of our understanding of the planetary dynamics. It is really impressive by the depth of the undertaken analysis. It is also well-written, well-structured, and well-illustrated. Nonetheless, some changes/additions are necessary.

1)    Introduction: please, formulate your objective clearly; however, the entire section can be shortened, and a part of the information can be moved to the methodological section.

2)    Section 2: each studied region (may be to call these as study areas? – region is something different) can be characterized briefly in regard to their geographical and oceanographical settings.

3)    Section 2: I'd prefer to learn about the specific software used for all these analyses and graphical representations.

4)    Section 4: in my opinion, this section should bear more oceanography-related interpretations. Please, try to explain briefly what do your findings mean for the understanding of the physical geography of oceans. I'm 100% sure that your manuscript can tell much to physical geographers, and, thus, you need to make the relevant additions.

5)    References: citing some "purely" geographical works would be helpful.
