5. The Warm Temperate Western Margin (Mediterranean) Climate
Location: Found between 30┬░ and 45┬░ N and S on the western sides of continents. Examples: Areas bordering the Mediterranean Sea, California (USA), Central Chile, Cape Town area of South Africa, and South-Western Australia.
Climate:
- Dry, warm summers: Caused by the shifting of the off-shore trade winds to this latitude in summer.
- Wet, mild winters: The region comes under the influence of the on-shore westerly winds in winter, bringing cyclonic rain.
- Abundant sunshine.
Vegetation & Wildlife:
- Mediterranean Vegetation: Trees have adapted to survive the long, dry summer. Features include thick barks, small leathery leaves, and deep taproots (e.g., Cork Oak, Olive).
- Shrublands: Known as Maquis (France), Chaparral (California), Matorral (Chile).
Human Adaptation:
- Ideally suited for Orchard Farming (citrus fruits like oranges, lemons, grapefruits).
- Viticulture (cultivation of grapes) is highly developed here (wine production in France, Italy, California).
- Tourism is a major industry due to the pleasant, sunny climate.
6. The Temperate Continental (Steppe) Climate
Location: Found in the interiors of continents, far from maritime influences (35┬░ to 55┬░ N and S). Examples: Steppes (Eurasia), Prairies (North America), Pampas (Argentina), Veld (South Africa), Downs (Australia).
Climate:
- Extreme, continental climate: Very warm summers and very cold winters (in the Northern Hemisphere).
- Light rainfall, mainly in late spring and early summer.
Vegetation & Wildlife:
- Temperate Grasslands: Almost entirely treeless due to low rainfall. Short, nutritious grasses.
- Wildlife: Bison (historically in N. America), wild horses, antelopes, coyotes, kangaroos (Australia).
Human Adaptation:
- The Steppes/Prairies are known as the "Granaries of the World."
- Highly mechanized, extensive wheat cultivation.
- Large-scale livestock ranching (cattle in Pampas and Prairies, sheep in Downs).
7. The Warm Temperate Eastern Margin (China Type)
Location: Found on the eastern margins of continents in warm temperate latitudes (20┬░ to 35┬░ N and S). Examples: Central/North China, SE USA (Gulf Coast), Natal (South Africa), Eastern Australia, Pampas margin.
Climate:
- Warm, humid summers and mild winters.
- Rainfall occurs throughout the year, but with a summer maximum.
- Frequently affected by severe tropical storms (Typhoons in China, Hurricanes in USA).
Vegetation & Wildlife:
- Evergreen Broadleaf Forests: Dense forests including oak, camphor, magnolia. Pines and cypresses are also common.
Human Adaptation:
- Most intensively cultivated region. High population density (China).
- Rice, tea, cotton, and tobacco are major crops.
- USA Gulf coast is famous for cotton and tobacco. Australian region for dairy and timber.
8. The Cool Temperate Western Margin (British Type)
Location: Western margins of continents between 45┬░ and 65┬░ N and S. Examples: North-West Europe (UK, France, Norway), British Columbia (Canada), Southern Chile, Tasmania, New Zealand.
Climate:
- Under the permanent influence of the Westerlies throughout the year.
- Mild winters and cool summers (moderate climate due to the ocean and warm ocean currents like the North Atlantic Drift).
- Rainfall throughout the year (cyclonic/frontal). No dry season.
Vegetation:
- Deciduous Forests: Trees shed their leaves in autumn to prepare for cold winter (Oak, Elm, Beech, Birch).
Human Adaptation:
- Highly industrialized and urbanized economies (Western Europe).
- Mixed farming (growing crops and raising animals simultaneously) is very common.
- Dairying is highly organized (e.g., New Zealand, Denmark).
9. The Cool Temperate Continental (Siberian/Taiga) Climate
Location: Found only in the Northern Hemisphere (50┬░ to 70┬░ N). Spreads across Canada, Scandinavia, and Russia (Siberia). Absent in the Southern Hemisphere due to lack of landmass at these latitudes.
Climate:
- Bitterly cold, long winters and short, cool summers.
- Largest annual range of temperature.
- Precipitation is low, mainly falling as snow in winter.
Vegetation:
- Coniferous Forests (Taiga): Evergreen, softwood trees with needle-like leaves (to prevent water loss and let snow slide off) and sloping branches. Pine, Fir, Spruce, Larch.
- The Taiga is the largest contiguous forest biome in the world.
Human Adaptation:
- Lumbering: The most important occupation. Softwood is used for paper, pulp, matches, and construction.
- Trapping of fur-bearing animals (mink, silver fox, ermine).
- Agriculture is minimal due to the short growing season and poor Podzol soils.
10. The Arctic and Polar (Tundra) Climate
Location: Found north of the Arctic Circle (66.5┬░ N) and south of the Antarctic Circle (66.5┬░ S). Northern coasts of Canada, Alaska, Greenland, Eurasia, and Antarctica.
Climate:
- Extreme cold throughout the year. 9-10 months of freezing winter.
- Extremely low precipitation (cold desert).
- Phenomenon of the "Midnight Sun" during summer.
Vegetation & Wildlife:
- Tundra: Treeless landscape. Vegetation is limited to mosses, lichens, and stunted dwarf willows during the brief summer.
- Subsoil remains permanently frozen (Permafrost).
- Wildlife: Animals have thick fur or blubber. Polar bears, walruses, seals, Arctic foxes, reindeer (caribou).
Human Adaptation:
- Very sparse population.
- Traditional livelihoods include hunting, fishing, and reindeer herding by indigenous peoples (Inuits/Eskimos in America, Lapps/Sami in Scandinavia, Samoyeds in Siberia).
- Recent discovery of minerals (oil in Alaska, iron ore) has brought modern settlements.
