What is the climate of the Arctic tundra?
Tundra regions typically get less than 25 centimeters (10 inches) of precipitation annually, which means these areas are also considered deserts. They have long, cold winters with high winds and average temperatures below freezing for six to ten months of the year.
What happens to the Arctic tundra in the winter?
Since the arctic tundra is very close to the north pole, the nights are very long. At the deepest points in the winter the sun may be gone for several weeks straight. This leads to the very cold temperatures: with an average of -34°C during the winter and in the coldest days dipping as cold as -45°C.
What is the temperature of the tundra in winter?
-34° C
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.
How cold can the Arctic tundra get?
-30 to 20 degrees Fahrenheit
The Arctic tundra, where the average temperature is -30 to 20 degrees Fahrenheit (-34 to -6 degrees Celsius), supports a variety of animal species, including Arctic foxes, polar bears, gray wolves, caribou, snow geese, and musk oxen.
Do humans live in the Arctic tundra?
Humans have been part of the tundra ecosystem for thousands of years. The indigenous people of Alaska’s tundra regions are the Aleut, Alutiiq, Inupiat, Central Yup’ik and Siberian Yupik. Originally nomadic, Alaska Natives have now settled in permanent villages and towns.
How much snow does the Arctic tundra get a year?
Over most of the Arctic tundra, annual precipitation, measured as liquid water, amounts to less than 38 cm (15 inches), roughly two-thirds of it falling as summer rain. The remainder falls in expanded form as snow, which can reach total accumulations of 64 cm (25 inches) to (rarely) more than 191 cm (75 inches).
Why are tundras so cold?
The temperatures are so cold that there is a layer of permanently frozen ground below the surface, called permafrost. This permafrost is a defining characteristic of the tundra biome. The trees that do manage to grow stay close to the ground so they are insulated by snow during the cold winters.
Does the arctic tundra have seasons?
Arctic tundra contains areas of stark landscape and is frozen for much of the year. There are two main seasons, winter and summer, in the polar tundra areas. During the winter it is very cold and dark, with the average temperature around −28 °C (−18 °F), sometimes dipping as low as −50 °C (−58 °F).
Why is it hard to live in the tundra?
The Arctic tundra is characterized by its layer of permafrost or permanently frozen subsoil that contains mostly gravel and nutrient-poor soil. These animals are adapted to live in the cold, harsh conditions of the tundra, but most hibernate or migrate to survive the brutal Arctic tundra winters.
What is the average rainfall in the Arctic tundra?
Arctic When it comes to precipitation the Tundra is more like a desert. It only gets about 6-10 inches (mostly snow) each year The rainfall is 150 to 250 mm annually. The summer growing season is 50 – 60 days.
What are facts about the Arctic tundra?

What is the climate in the Arctic tundra?
Tundra ecosystems are treeless regions found in the Arctic and on the tops of mountains, where the climate is cold and windy, and rainfall is scant. Tundra lands are covered with snow for much of the year, but summer brings bursts of wildflowers. Plants and animals in tundras.
What plants live in the Arctic tundra?
Approximately 1,700 species of plants live on the Arctic tundra, including flowering plants, dwarf shrubs, herbs, grasses, mosses, and lichens. The tundra is characterized by permafrost, a layer of soil and partially decomposed organic matter that is frozen year-round.
