Editing Taiga (section)

===Temperature===
After the permanent ice caps and [[tundra]], taiga is the terrestrial [[biome]] with the lowest annual average temperatures, with mean annual temperature generally varying from {{cvt|−5|to|5|C|F}}.<ref>{{cite web|url=http://www.marietta.edu/~biol/biomes/boreal.htm |title=Marietta the Taiga and Boreal forest |publisher=Marietta.edu |access-date=21 February 2011}}</ref> Extreme winter minimums in the northern taiga are typically lower than those of the tundra. There are taiga areas of eastern Siberia and interior Alaska-[[Yukon]] where the mean annual temperature reaches down to {{cvt|−10|C|F}},<ref>{{cite web|url=http://www.worldclimate.com/cgi-bin/data.pl?ref=N62E129+1102+24959W |title=Yakutsk climate |publisher=Worldclimate.com |date=4 February 2007 |access-date=21 February 2011}}</ref><ref>{{WWF ecoregion|id=na0607 |name= Interior Alaska-Yukon lowland taiga |access-date=21 February 2011}}</ref> and the [[Oymyakon|lowest reliably recorded temperatures]] in the [[Northern Hemisphere]] were recorded in the taiga of northeastern Russia.

Taiga has a [[subarctic climate]] with very large temperature range between seasons. {{cvt|−20|C|F}} would be a typical winter day temperature and {{cvt|18|C|F}} an average summer day, but the long, cold winter is the dominant feature. This climate is classified as ''Dfc'', ''Dwc'', ''Dsc'', ''Dfd'' and ''Dwd'' in the [[Köppen climate classification]] scheme,<ref>{{cite web |url=http://www.radford.edu/~swoodwar/CLASSES/GEOG235/biomes/taiga/taiga.html |title=radford:Taiga climate |publisher=Radford.edu |access-date=21 February 2011 |url-status=dead |archive-url=https://web.archive.org/web/20110609021800/http://www.radford.edu/~swoodwar/CLASSES/GEOG235/biomes/taiga/taiga.html |archive-date=9 June 2011 }}</ref> meaning that the short summers (24&nbsp;h average {{cvt|10|C|F}} or more), although generally warm and humid, only last 1–3 months, while winters, with average temperatures below freezing, last 5–7 months.

In Siberian taiga the average temperature of the coldest month is between {{convert|-6|°C}} and {{convert|-50|°C}}.<ref name="VOL page 568">''Encyclopedia Universalis'' édition 1976 Vol. 2 ASIE – Géographie physique, p. 568 {{in lang|fr}}</ref> There are also some much smaller areas grading towards the oceanic ''Cfc'' climate with milder winters, whilst the extreme south and (in Eurasia) west of the taiga reaches into [[humid continental climate]]s (''Dfb'', ''Dwb'') with longer summers.

According to some sources, the boreal forest grades into a temperate mixed forest when mean annual temperature reaches about {{cvt|3|C|F}}.<ref>{{WWF ecoregion|id=na0406 |name=The eastern forest – boreal transition|access-date=21 February 2011}}</ref> [[Discontinuous permafrost]] is found in areas with mean annual temperature below freezing, whilst in the ''Dfd'' and ''Dwd'' climate zones [[continuous permafrost]] occurs and restricts growth to very shallow-rooted trees like [[Siberian larch]].
