Köppen Classification: Continental Subarctic Climate



This climate type is dominated by the winter season, a long, bitterly cold period with short, clear days, relatively little precipitation mostly in the form of snow, and low humidity. It is located north of the humid continental climate, from about 50° to 70° N, in a broad swath extending from Alaska to Newfoundland in North America and from northern Scandinavia to Siberia in Eurasia. In Asia the Siberian anticyclone, the source of continental polar air, dominates the interior of the continent. The North American representative of this climate is not as severe but is still profoundly cold. Mean monthly temperatures are below freezing for six to eight months, with an average frost-free period of only 50-90 days per year, and snow remains on the ground for many months. Summers are short and mild, with long days and a prevalence of frontal precipitation associated with maritime tropical air within traveling cyclones. Annual precipitation totals are mostly less than 500mm (19.69 in), with a concentration in the summer.

The Köppen Climate Classification subtype for this climate is "Dfc". (Continental Subarctic Climate).
