Climate
Temperature
In the Tundra, the majority of the year is characterized by a frigid winter season where the temperatures average -20 to -30. During the majority of the year the sun may not rise above the horizon at all during the long, dark winter months (Blue). In the summer, which rangesfrom 50-60 days the sun shines for endless days during the brief growing season which averages 35-45 degrees, occassionally reaching a temperature above 50 (National Geographic).
Precipitation
This is one of the driest biomes on the planet, with annual rainfall (which includes melting snow) averaging between 6-10 inches a year ( the tundra biome). To put that in perspective, the sahara desert averages 3-5 inches per year! This fact is what makes the tundra a 'cold desert' (National Geographic).
