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.
There are two types of polar climate: ET, or tundra climate; and EF, or ice cap climate. A tundra climate is characterized by having at least one month whose average temperature is above 0 Â°C (32 Â°F), while an ice cap climate has no months above 0 Â°C (32 Â°F). In a tundra climate, trees cannot grow, but other specialized plants can grow.
