amount of precipitation in tundra forest
1 dry conifer forests: dominate higher elevation zones; low precipitation. 2  mediterranean forests: precipitation is concentrated in winter, less than 100 cm per year. 3  temperate coniferous: mild winters, high annual precipitation (greater than 200 cm). Precipitation in the tundra totals 150 to 250 mm a year, including melted snow. That's less than most of the world's greatest deserts! Still, the tundra is usually a wet place because the low temperatures cause evaporation of water to be slow. 1 mediterranean forests: precipitation is concentrated in winter, less than 100 cm per year. 2  temperate coniferous: mild winters, high annual precipitation (greater than 200 cm). 3  temperate broad-leaved rainforests: mild, frost-free winters, high precipitation (more than 150 cm) evenly distributed throughout the year. Arctic tundra contains areas of stark landscape and is frozen for much of the year. The soil there is frozen from 25–90 cm (10–35 in) down, and it is impossible for trees to grow. Much of the arctic has rain and fog in the summers, and water gathers in bogs and ponds. Vegetation in the tundra has adapted to the cold and the short growing season. Mosses, sedges, and lichens are common, while few trees grow in the tundra. The trees that do manage to grow stay close to the ground so they are insulated by snow during the cold winters. Today, forests occupy approximately one-third of Earth's land area, account for over two-thirds of the leaf area of land plants, and contain about 70% of carbon present in living things. Tundra tends to be windy, with winds often blowing upwards of 50–100 km/h (30–60 mph). However, in terms of precipitation, it is desert-like, with only about 15–25 cm (6–10 in) falling per year (the summer is typically the season of maximum precipitation). Description. The tundra is the coldest of the biomes. It also receives low amounts of precipitation, making the tundra similar to a desert. Tundra is found in the regions just below the ice caps of the Arctic, extending across North America, to Europe, and Siberia in Asia. Much of Alaska and about half of Canada are in the tundra biome. 1 temperate coniferous: mild winters, high annual precipitation (greater than 200 cm). 2  temperate broad-leaved rainforests: mild, frost-free winters, high precipitation (more than 150 cm) evenly distributed throughout the year. 1 Precipitation is evenly distributed throughout the year, with annual rainfall exceeding 200 cm. 2  Soil is nutrient-poor and acidic. 3  Decomposition is rapid and soils are subject to heavy leaching. 4  Canopy in tropical forests is multilayered and continuous, allowing little light penetration.
