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.
Tundra: Tundra is separated into two types: â¢ Arctic tundra â¢ Alpine tundra Arctic tundra Arctic tundra is located in the northern hemisphere, encircling the North Pole and extending south to the coniferous forests of the taiga. The arctic is known for its cold, desert-like conditions. The growing season ranges from 50 to 60 days. The average winter temperature is -34Â° C (-30Â° F), but the average summer temperature is 3-12Â° C (37-54Â° F) which enables this biome to sustain life. Rainfall may vary in different regions of the arctic.
