The authors should make the appropriate edits as suggested by the reviewers.

Hello Dr. Li et al.
I have reviewed your revised manuscript and have found some technical issues that need to be addressed. They are listed below.

1) All times in the article should be referenced as "0000 UTC" format as opposed to "00Z". Please ensure all times appear in the the full UTC format.
2) I noticed that none of the figures/tables appear in the main text of the article, but the captions do appear. I am not sure if what you have done is required by HESS or whether the figures were mistakenly not inserted.
3) There appear to be random "boxes" around some characters within the text. This also appears around Equation 1 as well. I am not sure if this was an error in the PDF rendering process.
4) Figure 9 is very small. I suggest stacking them on top of one another as opposed to having them appear side by side, so each "globe" will be larger. You will have to edit your caption to reflect this change.

Once you have addressed these points, we will publish the article. You will have to resubmit your revised article.

Cheers and thanks, John.

Hello Dr. Li et al. I have reviewed the revised manuscript and have found MANY grammatical errors that need correcting before final publication. Please ensure the entire manuscript has been reviewed and edited where needed. Figure 7 and References also need some attention.

Comments are below.

abstract: “ … a Rossby wave train originates from western Pacific and propagates into midlatitude over North America …”. Need “the” before “western” and “midlatitude” should be “midlatitudes”.

Figure 7: put plots on top of each other to make them larger - all axes/title text are too small.

Format references so there are clear breaks between each article.

line 281 discussion: “the precipitation in the Western Canadian Prairie …”. “Prairie” should be “Prairies”.

line 282 discussion: “… more extended dry spells tend to occur in Canadian Prairies during …”. Need “the” before Canadian.

line 311 discussion: “… MJO-4 index cannot determine the sign of precipitation anomaly in the Prairies alone.” Need “the” before “precipitation”.

lines 330-332, Conclusion: This entire first sentence has poor grammar.

line 333 conclusions: “… through the propagation of stationary Rossby wave from the western Pacific …”. Wave should be “waves”.

line 342 conclusions: “… can propagate into western Canada if they oriented relatively zonally.” Need “are” before “oriented”.
