I will try to review this as I can do. I am new to reviewing GA, so any assistance could be helpful. MarioJump83! 10:45, 7 February 2021 (UTC)Reply

First assessment (the final one will be not in the table form)
Rate Attribute Review Comment
1. Well-written:
  1a. the prose is clear, concise, and understandable to an appropriately broad audience; spelling and grammar are correct. This article has been done by someone from WP:GOCE, as such this article passes this criteria.
  1b. it complies with the Manual of Style guidelines for lead sections, layout, words to watch, fiction, and list incorporation. The article is very clearly within the MOS guidelines. Regarding embedded lists, the information presented are better suited to a list.
2. Verifiable with no original research:
  2a. it contains a list of all references (sources of information), presented in accordance with the layout style guideline. Certainly passed.
  2b. reliable sources are cited inline. All content that could reasonably be challenged, except for plot summaries and that which summarizes cited content elsewhere in the article, must be cited no later than the end of the paragraph (or line if the content is not in prose). The large majority of this article are from academic sources.
  2c. it contains no original research. Nearly all, if not all of this article are sourced to the reliable sources, and for all purposes this article passed.
  2d. it contains no copyright violations or plagiarism. Thanks Chidgk1 for help.
3. Broad in its coverage:
  3a. it addresses the main aspects of the topic. The coverage are definitely outstanding, I don't think that there is much out of scope.
  3b. it stays focused on the topic without going into unnecessary detail (see summary style). Some parts of the article might be too complicated, I am not very sure.
  4. Neutral: it represents viewpoints fairly and without editorial bias, giving due weight to each. The POV from this article is neutral from what I have seen.
  5. Stable: it does not change significantly from day to day because of an ongoing edit war or content dispute. Based on the edit history of this article, this is definitely stable for many reasons.
6. Illustrated, if possible, by media such as images, video, or audio:
  6a. media are tagged with their copyright statuses, and valid non-free use rationales are provided for non-free content. Pass.
  6b. media are relevant to the topic, and have suitable captions. Two of these images are relevant to the topic.
  7. Overall assessment. This article is close to passing all GA criteria, but I have some slight concerns with two of these criteria, which is possible complications. and plagiarism/direct copies from the sources to the article.
That's my assessment. This is based on my quick review of the article - please note that I will probably miss some of them. I don't give any suggestions regarding the GA, it will be done by LightandDark2000. MarioJump83! 03:50, 22 February 2021 (UTC)Reply

Second Opinion by Femkemilene

edit
  • I was wondering if it's accurate to say it's an oscillation? The article states instead: The PMM appears to be mainly a consequence of stochastic (random) climate forcing in the extratropics. A lot of these stochastic modes of variability used to be called oscillations, but no evidence of dominant frequencies / cyclicity was found, leading to an awkward name (have been reading about the Atlantic multidecadal oscillation recently, where current evidence does not support internal cyclic behaviour). I checked the source by Stuecker, which consistently calls it a mode, which is a term encompassing both stochastic and oscillatory modes of variability. The Amaya source doesn't call it an oscillation either. FemkeMilene (talk) 20:58, 5 March 2021 (UTC). The definition of aReply
    I don't think it is but we have climate oscillation but not climate mode. I'll replace the names. Jo-Jo Eumerus (talk) 10:49, 6 March 2021 (UTC)Reply
    I've made climate mode a redirect to Climate variability and change, just like climate oscillation is. :). FemkeMilene (talk) 11:01, 6 March 2021 (UTC)Reply
  • The Pacific Meridional Mode is a form of coupled variability between the latitude of the Intertropical Convergence Zone (ITCZ) and north-south sea surface temperature (SST) gradients in the subtropical Pacific Ocean -> Don't understand. How can something be a variability between a place and a gradient?
    Well, it's "coupled" not "between". It's variations in SSTs and ITCZ latitude that are connected. Jo-Jo Eumerus (talk) 10:49, 6 March 2021 (UTC)Reply
  • not sure about glossing decadal as 10-year, as that implies an 'exact' frequency, instead of a broad range of frequencies. Maybe tens of years instead?
    Removed it. Jo-Jo Eumerus (talk) 10:49, 6 March 2021 (UTC)Reply
  • The role of ENSO at inducing PMM changes is little studied -> prose?
    Rewrote this a bit. Jo-Jo Eumerus (talk) 10:49, 6 March 2021 (UTC)Reply
  • The second sentence will be easier to understand if you focus either on the positive or negative phase. It's positive phase is characterised by weaker trade winds in the north-east Pacific ..., and visa versa for its negative phase
    True, but it would miss out a lot of information that way. Jo-Jo Eumerus (talk) 10:49, 6 March 2021 (UTC)Reply
    I don't think it would, considering you end the sentence with visa versa (or the reverse). I don't have the mental capacity to follow these sentences as you need to remember that positive came first for another three effects. And I've probably got more experience reading these type of sentences than most of our readers. FemkeMilene (talk) 11:04, 6 March 2021 (UTC)Reply
    Rewrote this a little. Jo-Jo Eumerus (talk) 15:55, 6 March 2021 (UTC)Reply
  • does the first figure portray a positive or negative phase?
    Positive; added it. Jo-Jo Eumerus (talk) 10:49, 6 March 2021 (UTC)Reply
  • The PMM is not the same thing as the El Niño-Southern Oscillation (ENSO) is it necessary to say this? I'm assuming this article will mostly be read by postgraduates that now and so is a tropical oscillation.
    Eh, I prefer to not make too many assumptions about who will read this. Jo-Jo Eumerus (talk) 10:49, 6 March 2021 (UTC)Reply
    Agree with not assuming readership too much. For the people that don't quite know what ENSO is, would they jump to the conclusion they are the same? If you mention how they are related, you already state they are not the same, so I maintain this is redundant. FemkeMilene (talk) 11:11, 6 March 2021 (UTC)Reply
    I wouldn't assume that people will read it that way. And I am sure I've seen publications which specifically differentiate between the two. Jo-Jo Eumerus (talk) 15:55, 6 March 2021 (UTC)Reply
  • I think the article uses to many lists. The last list element of the triggers section seems to be an effect rather than a trigger: Simon Wang, Jiang and Fosu (2015) proposed that ENSO triggering can occur through an Indian Ocean-West Pacific-PMM route, but the mechanism is unclear
    I see, but I don't think these things lend themselves well to a prose only presentation unless 2021 sees additional sources published with which some of the dot points can be expanded to paragraph length. Jo-Jo Eumerus (talk) 10:49, 6 March 2021 (UTC)Reply
  • The PMM can induce mainly warm events -> The PMM induces mainly warm events
    Corrected. Jo-Jo Eumerus (talk) 10:49, 6 March 2021 (UTC)Reply
  • (CP Niño or El Niño Modoki) -> unnecessary jargon?
    Nah, I would not assume that everybody knows that CP Niño = Modoki Niño. Jo-Jo Eumerus (talk) 10:49, 6 March 2021 (UTC)Reply
    I'm not saying they know; but I don't think Modoki El Nino is a familiar phrase at all, so I feel it's the introduction of jargon that's not used further in the article. FemkeMilene (talk) 11:12, 6 March 2021 (UTC)Reply
    Well, "Modoki" is the name under which I first heard the concept, thus I'd actually disagree on this point. Jo-Jo Eumerus (talk) 15:55, 6 March 2021 (UTC)Reply
  • Tuo, Yu and Hu (2019) discovered that PPM modulated the activity of mesoscale ocean eddies in the South China Sea, and its southern hemisphere equivalent,[54] until 2004 when the relationship largely ceased -> are statistical flukes due? That list is already quite long.
    Good question, I've seen some studies referencing these findings so I think they are. Jo-Jo Eumerus (talk) 10:49, 6 March 2021 (UTC)Reply
  • LightandDark2000; the good article criteria only ask for a broad coverage, not a comprehensive coverage. I think it clearly meets that criterion, might even come close to the FA criterion. FemkeMilene (talk) 08:55, 6 March 2021 (UTC)Reply
    Aye, I am pretty sure this one is comprehensive. The main reason I am sending it to GA rather than FA is because a lot of the sources are "hey, I found a PMM teleconnection!" rather than review articles; that's why there is so much in-text attribution and I am not sure if either is OK at FA level - none of the FAs I've written is sourced like this.

Third Opinion by LightandDark2000

edit

I will also review this article. In addition, I will try to grab one of the other senior editors with more of a background in meteorology (such as Hurricane Noah) to ensure that this article is accurate and comprehensive in coverage. LightandDark2000 🌀 (talk) 23:46, 7 February 2021 (UTC)Reply

I'll try review this article next weekend, when I have more time. Anyway, I'm glad to see that one of the other reviewers feels that this article is quite comprehensive. I always look for comprehensive coverage and solid writing, even in GA candidates. LightandDark2000 🌀 (talk) 19:10, 6 March 2021 (UTC)Reply

Another phrase with run-on and ambiguity issues. Change to "while during the summer, low atmospheric pressure over the northern United States and high atmospheric pressure over the eastern United States favor precipitation in the Midwest." Also, link "northern United States" to Northern United States, link "eastern United States" to Eastern United States, and link "Midwest" to Midwestern United States.

  • They further suggest PMM might influence the seasonality of El Niño events, as PMM events occur mainly during spring. Change to "They further suggested that the PMM might influence the the seasonality of El Niño events, as PMM events occur mainly during the spring."
    Partly done. Jo-Jo Eumerus (talk) 10:24, 14 March 2021 (UTC)Reply
  • events although there is no clear consensus on this association. Add a comma after "events" (before the citation tag).

PMM and anthropogenic climate change
  • Liguori and Lorenzo (2018) proposed the effect would become noticeable by 2020. I won't require this for a GA promotion, but since it's currently 2021, has this prediction been verified yet? I think it would be a good thing for readers to know.
    I don't think we know yet whether this is correct. Let's wait until Christmas, when I make my yearly update. Jo-Jo Eumerus (talk) 10:24, 14 March 2021 (UTC)Reply
  • during the few decades preceding 2020 and according to Liguori and Lorenzo (2018) may explain an increase in ENSO activity until 2100, This is a run-on. Change to "during the few decades preceding 2020, and according to Liguori and Lorenzo (2018), may explain an increase in ENSO activity until 2100,".
    I've split this sentence. Jo-Jo Eumerus (talk) 10:24, 14 March 2021 (UTC)Reply

  • the increasing trend to central Pacific El Niño events Change "increasing trend to" to "increasing trend of".
  • Link 21st century.

Name and use
Images
  • I won't require this change for a GA promotion, but since this article is very technical in nature, I think that it could use some more images and/or diagrams. It would really help the readers who aren't professional meteorologists.
    That's being discussed on the talk page - it's not as easy as it sounds to make images for this topic. Jo-Jo Eumerus (talk) 10:24, 14 March 2021 (UTC)Reply

These are all of the issues that I have identified. While the article is quite comprehensive and well-written, there are a handful of issues that need to be resolved before it can be promoted to GA status, including an severe hyperlink issue. LightandDark2000 🌀 (talk) 23:18, 13 March 2021 (UTC)Reply

According to red link policy, red links should be present only if new articles will be created for those subjects. If new articles will be created for those topics in the near future, then I guess I can tolerate them. Otherwise, I think that this article is ready. I also got an informal review from Hurricane Noah off-wiki, and he believes that the article does not have any major issues. I'll let MarioJump83 make the call to promote this article, since he was the original reviewer. LightandDark2000 🌀 (talk) 03:46, 15 March 2021 (UTC)Reply
Probably not "in the near future" for lack of time but I am certain that the redlinked topics meet WP:N. Jo-Jo Eumerus (talk) 08:46, 15 March 2021 (UTC)Reply
