Tundra vegetation is composed of dwarf shrubs, sedges and grasses, mosses, and lichens. It is noted for its frost-molded landscapes, extremely low temperatures, little precipitation, poor nutrients, and short growing seasons. Tundra climate is mainly found along the coast of the Arctic Ocean. Temperatures hardly surpass -18 degrees Fahrenheit or -8 degrees Celsius. Due to dry conditions, poor soil quality, extremely cold temperatures, and permafrost, … It gets less than 10 inches (or 250mm) of rainfall per year and has no growing season. The winter is long and very cold, with a short summer. Omissions? Winters in the tundra are long, freezing and dark.

Nights can last for weeks when the sun barely rises during some months in the winter, and the temperature can drop to -94° F (-70° C). Tundra is a transition climate between Ice Cap and Subarctic, similar to Semiarid being a transition between Arid and more humid climate. Tundra grasslands. Dead organic material functions as a nutrient pool. It also receives low amounts of precipitation, making the tundra similar to a desert. An increase in wooded plants in both savanna and tundra regions is caused by increased rainfall and temperatures that can be attributed to climate change, UK ecologists have concluded.

The tundra is the coldest of all the biomes with an annual average temperature of less than 5°C, and precipitation (mostly in the form of snow) less than 100 mm per year. Tundra Biome Climate. Shrub expansion can amplify warming by altering the surface albedo, energy and water balance, and permafrost temperatures. Rainfall may vary in different regions of the arctic.Yearly precipitation, including melting snow, is 15 to 25 cm (6 to 10 inches). In areas dominated by the tundra climate type, winters are long and cold (temperatures may be below 0 °C [32 °F] for 6 to 10 months), especially in the region north of the Arctic Circle where, for at least one day in the year, the Sun does not rise.
