facts • Temperate deciduous forest have a smaller fraction of original vegetation remaining than boreal or tropical rain forest and also have been more severely impact by land use change and air pollution. • It is colder and \or moisture part of the temperature • The latitude range is anywhere from 23 ° north to 38 ° south. • this biome and its climate is that it has four distinct seasons; spring, summer, autumn, and winter. Most deciduous forests have mild summers averaging about 70 °F. Summer months usually begin in early June and end in late August. Winter months don't begin until December. Winter temperatures are fairly cool with an average temperature of a little below freezing. Almost all of the world's deciduous forest is located by an ocean. The ocean and the wind are two big factors of why the temperature and climate change so much in this biome. • Climate is a mix of temperature and precipitation. Deciduous forests have almost 14 inches of rain in the winter months and more than 18 inches of rain in the summer. • with average velocity of ~0.2 cm s-1.
Temperate deciduous forests are located in the mid-latitude areas which shows that they are found between the polar region and the tropics. The deciduous forest regions are exposed to warm and cold weather masses, which cause this area to have four seasons. The temperature varies tremendously from season to season with cold winters and hot, wet summers. The average yearly temperature is about 10°C. The areas in which deciduous forests are located get about 750 to 1,500 mm of precipitation spread fairly evenly through the year.
During the fall, trees change color and then lose their leaves. This is in preparation for the winter season. Because it gets so cold, the trees have adapted to the winter by going into a period of dormancy or sleep. They also have thick bark to protect them from the cold weather. Trees flower and grow during the spring and summer growing season. • Many different types of trees, shrubs, and herbs grow in deciduous forests. Most of the trees are broadleaf trees such as oak, maple, beech, hickory and chestnut. There are also several different kinds of plants like mountain laurel, azaleas and mosses that live on the shady forest floor where only small amounts of sunlight get through.
Temperate forests are often called deciduous forests. In a temperate forest, most of the trees lose their leaves in the winter. During the fall, when the weather gets cooler, the trees begin to close. Their leaves turn beautiful shades of colors in the fall.
Patterns There are a few weather patterns but the one that I think is the most important is that the weather starts out low and raises than goes down this could effect organisms because of the severe weather change by adaptation to the weather such as the animals that are use to warm weather.
Review • (Temperature) -30°C to 30°C, yearly average is 10°C, hot summers, cold winters • (Precipitation) 750 to 1,500 mm of rain per year • Temperate deciduous forests are most notable because they go through four seasons. Leaves change color in autumn, fall off in the winter, and grow back in the spring; this adaptation allows plants to survive the cold winters.
Facts Temperate deciduous forests are found in middle latitudes with temperate climates. Deciduous means that the trees in this forest change with the seasons. In fall, the leaves change color. In fall and winter the leaves fall off the tree. In spring the leaves grow back. Examples of deciduous trees are maples, oaks, and elms.
Temperate climates are not considered to have extremes of hot or cold, compared to deserts or polar regions. The average annual temperature in a temperate deciduous forest is 10°C (50°F). Weather changes throughout the year, however winters have short days with little sunlight. Summer days are long and sunny. The temperature in January might drop to –12°C (10F). In summer, it might be as warm as 27°C (81°F). The growing season lasts 140 to 200 days, or 4 to 6 months.
