Subarctic climate

The subarctic climate (also called subpolar climate, or boreal climate) is a continental climate with long, cold (often very cold) winters, and short, warm to cool summers. It is found on large landmasses, often away from the moderating effects of an ocean, generally at latitudes from 50°N to 70°N, poleward of the humid continental climates. Subarctic or boreal climates are the source regions for the cold air that affects temperate latitudes to the south in winter. These climates represent Köppen climate classification Dfc, Dwc, Dsc, Dfd, Dwd and Dsd.

Description

This type of climate offers some of the most extreme seasonal temperature variations found on the planet: in winter, temperatures can drop to below −50 °C (−58 °F) and in summer, the temperature may exceed 26 °C (79 °F). However, the summers are short; no more than three months of the year (but at least one month) must have a 24-hour average temperature of at least 10 °C (50 °F) to fall into this category of climate, and the coldest month should average below 0 °C (32 °F) (or −3 °C (27 °F)). Record low temperatures can approach −70 °C (−94 °F).[1]

With 5–7 consecutive months when the average temperature is below freezing, all moisture in the soil and subsoil freezes solidly to depths of many feet. Summer warmth is insufficient to thaw more than a few surface feet, so permafrost prevails under most areas not near the southern boundary of this climate zone. Seasonal thaw penetrates from 2 to 14 ft (0.6 to 4.3 m), depending on latitude, aspect, and type of ground.[2] Some northern areas with subarctic climates located near oceans (southern Alaska, the northern fringe of Europe, Sakhalin Oblast and Kamchatka Oblast), have milder winters and no permafrost, and are more suited for farming unless precipitation is excessive. The frost-free season is very short, varying from about 45 to 100 days at most, and a freeze can occur anytime outside the summer months in many areas.

Description

The first D indicates continentality, with the coldest month below 0 °C (32 °F) (or −3 °C (27 °F)).

The second letter denotes precipitation patterns:

  • s: A dry summerthe driest month in the high-sun half of the year (April to September in the Northern Hemisphere, October to March in the Southern Hemisphere) has less than 30 millimetres (1.18 in)/40 millimetres (1.57 in) of rainfall and has exactly or less than 13 the precipitation of the wettest month in the low-sun half of the year (October to March in the Northern Hemisphere, April to September in the Southern Hemisphere),
  • w: A dry winterthe driest month in the low-sun half of the year has exactly or less than one‑tenth of the precipitation found in the wettest month in the summer half of the year,
  • f: No dry seasondoes not meet either of the alternative specifications above; precipitation and humidity are often high year-round.

The third letter denotes temperature:

  • c: Regular subarctic, only 1–3 months above 10 °C (50.0 °F), coldest month between 0 °C (32 °F) (or −3 °C (27 °F)) and −38 °C (−36.4 °F).
  • d: Severely cold subarctic, only 1–3 months above 10 °C (50.0 °F), coldest month at or below −38 °C (−36.4 °F).

Precipitation

Most subarctic climates have little precipitation, typically no more than 380 mm (15 in) over an entire year due to the low temperatures and evapotranspiration. Away from the coasts, precipitation occurs mostly in the summer months, while in coastal areas with subarctic climates the heaviest precipitation is usually during the autumn months when the relative warmth of sea vis-à-vis land is greatest. Low precipitation, by the standards of more temperate regions with longer summers and warmer winters, is typically sufficient in view of the very low evapotranspiration to allow a water-logged terrain in many areas of subarctic climate and to permit snow cover during winter.

A notable exception to this pattern is that subarctic climates occurring at high elevations in otherwise temperate regions have extremely high precipitation due to orographic lift. Mount Washington, with temperatures typical of a subarctic climate, receives an average rain-equivalent of 101.91 inches (2,588.5 mm) of precipitation per year.[3] Coastal areas of Khabarovsk Krai also have much higher precipitation in summer due to orographic influences (up to 175 millimetres (6.9 in) in July in some areas), whilst the mountainous Kamchatka peninsula and Sakhalin island are even wetter, since orographic moisture isn't confined to the warmer months and creates large glaciers in Kamchatka. Labrador, in eastern Canada, is similarly wet throughout the year due to the semi-permanent Icelandic Low and can receive up to 1,300 millimetres (51 in) of rainfall equivalent per year, creating a snow cover of up to 1.5 metres (59 in) that does not melt until June.

Vegetation and land use

Vegetation in regions with subarctic climates is generally of low diversity, as only hardy tree species can survive the long winters and make use of the short summers. Trees are mostly limited to conifers, as few broadleaved trees are able to survive the very low temperatures in winter. This type of forest is also known as taiga, a term which is sometimes applied to the climate found therein as well. Even though the diversity may be low, the area and numbers are high, and the taiga (boreal) forest is the largest forest biome on the planet, with most of the forests located in Russia and Canada. The process by which plants become acclimated to cold temperatures is called hardening.

Agricultural potential is generally poor, due to the natural infertility of soils[4] and the prevalence of swamps and lakes left by departing ice sheets, and short growing seasons prohibit all but the hardiest of crops. Despite the short season, the long summer days at such latitudes do permit some agriculture. In some areas, ice has scoured rock surfaces bare, entirely stripping off the overburden. Elsewhere, rock basins have been formed and stream courses dammed, creating countless lakes.[2]

Distribution

Dfc and Dfd distribution

The Dfc climate, by far the most common subarctic type, is found in the following areas:[5][6]

View of pines in the Kuysumy mountains in Siberia

Further north in Siberia, continentality increases so much that winters can be exceptionally severe, averaging below −38 °C (−36 °F), even though the hottest month still averages more than 10 °C (50 °F). This creates Dfd climates, which are mostly found in the Sakha Republic:

Subarctic climate in Alaska, near Yukon

In the Southern Hemisphere, this climate exists only in small, isolated pockets in the Snowy Mountains of Australia, the Southern Alps of New Zealand, the Andes Mountains of Argentina, and the Lesotho Highlands.

Dsc and Dsd distribution

Climates classified as Dsc or Dsd, with a dry summer, are rare, occurring in very small areas at high elevation around the Mediterranean Basin, Iran, Kyrgyzstan, Afghanistan, Tajikistan, Alaska and other parts of the northwestern United States (Eastern Washington, Eastern Oregon, Southern Idaho, California's Eastern Sierra), the Russian Far East, Seneca, Oregon, and Atlin, British Columbia. Turkey is an exception with it being common in Northeast Anatolia and in the Taurus and Köroğlu Mountains.

Dwc and Dwd distribution

Climates classified as Dwc or Dwd, with a dry winter, are found in parts of East Asia, like China, where the Siberian High makes the winters colder than places like Scandinavia or Alaska interior but extremely dry (typically with around 5 millimeters (0.20 in) of rainfall equivalent per month), meaning that winter snow cover is very limited. The Dwc climate can be found in:

Should one go northward or even toward a polar sea, one finds that the warmest month has an average temperature of less than 10 °C (50 °F), and the subarctic climate grades into a tundra climate not at all suitable for trees. Southward, this climate grades into the humid continental climates with longer summers (and usually less-severe winters) allowing broadleaf trees; in a few locations close to a temperate sea (as in northern Norway and southern Alaska), this climate can grade into a short-summer version of an oceanic climate, the subpolar oceanic climate, as the sea is approached. In China and Mongolia, as one moves southwestwards or towards lower elevations, temperatures increase but precipitation is so low that the subarctic climate grades into a cold semi-arid climate.

In the Southern Hemisphere, small pockets of the Lesotho Highlands and the Drakensberg Mountains have a Dwc classification.
