Some subarctic animals include birds, lynx, reindeer, weasels and wolves.

I removed this "Agriculture is almost nonexistent, and confined to vegetables that can grow very quickly." because it is completely untrue. To give an example, 90% of Finland is within the sub-arctic climate area and I would not call its agriculture non-existent.--HJV 17:47, 10 May 2005 (UTC)[reply]

Precipitation

The opening sentence under "Precipitation" says, "Most subarctic climates have very big precipitation, typically no more than 15 inches (380 mm) over an entire day." Where did this come from? It doesn't make any sense. (Where in the world routinely has 380 mm (or 15 inches) of rain in a day? Certainly not the subarctic areas?) Is there a reason for its inclusion here?

The whole Precipitation section looks like it's been altered by someone. Compare the version for (13 May 2013‎ @ 18:55) with that of (16 April 2013 @ 22:01). The April 16 version had "very little precipitation, typically no more than 15 inches over an entire year." There are other changes. Mount Washington" was changed to "Mount Everest". "Labrador in eastern Canada" was changed to "Pitbull in eastern China". "Kamchatka" was changed to "Japan". --65.110.164.4 (talk) 19:16, 14 May 2013 (UTC)[reply]

I see it's been reverted back - thanks! Ondewelle (talk) 19:18, 18 May 2013 (UTC)[reply]

Large differences within the subarctic climate

The article seems to focus mainly on the type of subarctic climate found in Siberia and northern part of Canada - the one with extremely cold winters. There are significant areas with a subarctic climate with "only" 5 months below freezing, and where there is no permafrost. For instance, southern Alaska including Anchorage have no permafrost, the same goes for cities like Luleå, Oulu, Tromsø. Snow cover also insulates the ground against the cold, hence drier areas are more prone to soil freezing. What about cities with a summer (24-hr mean at least 10 centigrades) lasting more than 3 months, but less than 4 months, say 105 days? Provided coldest winter month is below -3 centigrades, is this a humid continental Dfb climate or Dfc subarctic climate? The frost free periode should here be something like 110 - 120 days or more.

Vegetation is sparse...is this correct, considering that the boreal forests are the largest in the world? Much fewer species, yes, but still....Orcaborealis 22:01, 6 November 2006 (UTC)[reply]

The Koppen climate classification defines a subarctic climate as having coldest month mean temperature below -3 centigrade and between one and three months over 10 centigrade. I found that a few towns in Newfoundland Island fit into this classification when I checked the Weatherbase.com and Worldclimate.com websites. —The preceding unsigned comment was added by 86.42.4.5 (talk)

And here is a link about the taiga and subarctic climate, thorough, divides the taiga (boreal forests) into subzones, and stating up to 100 frost free days.Orcaborealis 22:46, 6 November 2006 (UTC)[reply]

Frost-free season

Some areas which technically falls within subarctic climate have more than 100 days frost-free season. For instance Tromsø, with a frost-free season of approximately 140 days from last overnight spring frost to first autumn frost (see Talk:Geography of Norway), and also some parts of southern Alaska, see Anchorage.

No definitions for differences between subtypes

I presume the Df_, Dw_ and Ds_ stand for the same things as described in the Humid continental climate article, but this isn't described anywhere in this article. Additionally, the difference between D_c and D_d doesn't seem to be defined anywhere on Wikipedia. Can someone add definitions for the subtypes to the article? Daß Wölf 02:01, 12 November 2018 (UTC)[reply]

_ _ c and _ _ d define subarctic climates, this is dealt with under "Description". Arrecife (talk) 00:28, 1 October 2021 (UTC)[reply]

Dsd ???

I cannot find any weather station with a Dsd climate...does this climate even exist? I think Dsd should be taken out if not. Arrecife (talk) 00:31, 1 October 2021 (UTC)[reply]

To answer my own question, there is theoretically a Dsc climate bordering on Dsd at Seymchan, since November (27mm) has more than 3 times the precip. of April (8.5mm). But the Koppen formula is at fault here, as anyone can see that the summer is much wetter than the winter. The article uses common sense to classify it as Dfc, although this contradicts the formula. This kind of weirdness happens frequently with Csc and Dsc climates, climatologists need to revise the formula. Arrecife (talk) 03:51, 4 October 2021 (UTC)[reply]
