The Climate and Vegetation

• Europe’s climates vary from the tundra and subarctic regions of Iceland, Scandinavia, and Finland to the Mediterranean coasts of Italy, Spain, and Greece.

Introduction
• Europe’s northern latitude and its location near large bodies of water are major factors in determining the diversity of its climates and vegetation.

Europe’s Climate Regions• In spite of Europe’s northern location, most
of the continent has a mild climate.
REGION
• Europe’s peninsular location in relation to the sea helps explain its relatively mild climate.
• In western Europe–from the Arctic Circle to the Alps and from Ireland to the western parts of Poland, the Czech Republic, and Hungary–there is a marine west coast climate.

• Northwest Europe’s temperate, moist climate is caused by winds that blow across the continent from the Atlantic Ocean.
• Most of southern Europe has a Mediterranean climate.
Major Climate Regions

• The mistral, a strong, northerly wind from the Alps, may bring very cold air to southern France.

Major Climate Regions (cont.)
• Siroccos, hot winds from the North African deserts of Libya, can bring desert air and dust.

Major Climate Regions (cont.)
• Most of eastern and northern Europe and the southern parts of Sweden and Finland have a humid continental climate.
Section 2-6
Click the mouse button or press the Space Bar to display the information.
• Parts of Spain’s Meseta have a steppe, or partly dry, climate. • Most of Iceland and the northern parts of Scandinavia and Finland have subarctic and tundra climates.
• Tundra and subarctic regions have permafrost, soil that is often permanently frozen below the surface.
• A humid subtropical region stretches from northern Italy to the central part of the Balkan Peninsula.
Other Climates
Click the mouse button or press the Space Bar to display the information.
• Dry winds called foehns, blowing down from the mountains, can cause an avalanche, a mass of ice, snow, or rock sliding down a mountainside.
• The Alps have a highland climate with generally colder temperatures and more precipitation than other regions.

Europe’s Vegetation• The natural vegetation of Europe consists of forests,
grasslands, and tundra plants, which are closely linked to the climate regions.
HUMAN/ENVIRONMENT INTERACTION
• Changing climate patterns have affected vegetation, but people have caused even greater changes.
Section 2-9
Click the mouse button or press the Space Bar to display the information.
• Coniferous forests are common in northern Europe and in mountain areas.
• Mediterranean climates support broad-leaved evergreens, with tough, waxy leaves to conserve moisture.
• Parts of the North European Plain consist of grasslands.
• Deciduous forests, trees that lose their leaves, are the natural vegetation of Europe’s marine west coast climate region.

• The hot, dry summers of the Mediterranean area produce chaparral, or shrubs and short trees.

• The tundra region near Europe’s Arctic coast supports little vegetation.
• The upper slopes of the Alps resemble the tundra and support similar kinds of vegetation.

• Today, in much of the once-forested land, there are urban areas and farms.
• Because forests still cover parts of Scandinavia, Finland, Poland, Slovakia, and the Czech Republic, lumbering is an important industry in these regions.
• Europeans cut down most of the natural forests to clear the land for agriculture and industry.
Human Interaction
Section 2-12
Click the mouse button or press the Space Bar to display the information.
• Air pollution poses a serious threat to forests and other natural vegetation.
• In many industrialized countries, such as Germany, Belgium, Poland, and the Czech Republic, auto and factory pollution has brought widespread disaster to many woodlands.
• Some European governments regulate the cutting of trees to protect forests.
