Köppen climate classification was a good article candidate, but did not meet the good article criteria at the time. Once the objections listed below are addressed, the article can be renominated. You may also seek a review of the decision if you feel there was a mistake.
Date of review: September 26, 2006 |
Based on the consensus between me, Isomorphic and Dittaeva (see my talkpage), I moved the original Köppen climate classification scheme to this page, as it means the same thing, and the "scheme" was rather redundant. -- Matt Borak 13:00, 5 Mar 2004 (UTC)

[edit] Precip less than evap
(William M. Connolley 13:54, 2004 Mar 27 (UTC)) Arid/desert are "These climates are characterized by the fact that precipitation is less than evaporation." sez the page.
This makes no sense: apart from river/runoff, ppn=evap everywhere over land. In the sahara, ppn is definitely = evap, since there are no rivers.
The page actually says "These climates are characterized by the fact that precipitation is less than potential evapotranspiration." See the definition of potential evapotranspiration to understand this.
[edit] Trewartha
Suggestion: it seems to me that there is enough detail in the Trewartha climate article to split it off into its own article, then link to it. Comments? -- hike395 15:29, 28 Mar 2004 (UTC)
- I'm not shure. It seems to me that it is here on purpose because it depends on / references so much to the Köppen scheme. I think you should wait for a comment from the original author or ask him trough his talk page. Dittaeva 08:16, 29 Mar 2004 (UTC)
[edit] References
Maybe some of the References section should be removed. It seems rather redundant to keep listing the book, publisher, and author. VashiDonsk 03:40, 15 April 2006 (UTC)
- I agree, probably no need for references to each chapter of McKnight et al. individually. Deditos 12:10, 25 May 2006 (UTC).
[edit] Southern Hemisphere "D" climates
No "D" climates in the Southern hemisphere?
It's almost a quibble, but some highland areas in New Zealand have winters cold enough to qualify for "D" climates, but have cool summers just warm enough to remain outside of montane tundra (ET). These zones of D climates (Dfb or Dfc) are small, but they exist. They barely appear on most worldwide climatic maps or are treated with the portmonteau label as 'highland' climates.
More precisely, one can state that because of the configuration of land and seas in the Southern Hemisphere, "D" climates exist only in restricted areas of mountainous zones in the middle latitudes.--66.231.41.57 06:27, 23 April 2006 (UTC)
[edit] Failed "good article" nomination
This article failed good article nomination. This is how the article, as of September 26, 2006, compares against the six good article criteria:
- 1. Well written?: Fail This article gets very confusing in the first section titled "The scheme". Article also fails WP:LEAD.
- 2. Factually accurate?: Fail The only reference is a book. I would like to see some web references.
- 3. Broad in coverage?: Fail Could use a history section to tell how this idea was created.
- 4. Neutral point of view?: Pass
- 5. Article stability? Pass
- 6. Images?: Neutral Try to put some picture if possible. They are however not required.
When these issues are addressed, the article can be resubmitted for consideration. Thanks for your work so far. --Tarret 22:59, 26 September 2006 (UTC)
[edit] Milan
Milan in Italy does have summers warmer than 22 degr Celsius, the coldest winter month has an average of 1 degr C and there is, unlike most of the mediterranean, frequent summer precipitation. See here. Whether Britannica labels the climate continental or not does not say very much; many of the areas in the United States could be labeled continental as well. The temperature distinction between the humid continental (Dfa) and humid subtropical (Cfa) is the -3 degr C (0 C in the US) in the coldest month. The label subtropical might seem strange for a location where there might be snowing in winter, but that goes for many locations in the US and China as well...There is an area from the Po valley in northern Italy and in parts of the Balkan which fullfills all criteria given in the article.

[edit] Geiger
The first mention of "Köppen-Geiger" is the heading "World Map of the Köppen-Geiger climate classification..." and who this Geiger fellow is doesn't get mentioned at all. I assume it's Rudolf Geiger. Anyone wish to expand the article? —Pengo 14:04, 11 March 2007 (UTC)
