Tundra climate, major climate type of the KÃ¶ppen classification characterized by sub-freezing mean annual temperatures, large annual temperature ranges (but not as large as in the adjacent continental subarctic climate), and moderately low precipitation.

Because of the low temperatures, the ground is frozen (called permafrost, for permanently frozen ground). During the short summer, only the uppermost foot (30 cm) or less actually thaw.
