The average precipitation, including melting snow, in the tundra is between 6 and 10 inches per year. Coupled with strong drying winds, the annual precipitation makes the tundra an area of extreme weather.
The average winter temperature is -34 C (-30 F), but the average summer temperature is 3-12 C (37-54 F) which enables this biome to sustain life. Rainfall may vary in different regions of the arctic. Yearly precipitation, including melting snow, is 15 to 25 cm (6 to 10 inches). Soil is formed slowly.haracteristics of tundra include: 1  Extremely cold climate. 2  Low biotic diversity. 3  Simple vegetation structure. 4  Limitation of drainage. 5  Short season of growth and reproduction. 6  Energy and nutrients in the form of dead organic material.
