Coriolis Effect - - The way Earth's rotation makes winds in the Northern Hemisphere curve to the
right and winds in the Southern Hemisphere curve to the left.
- adds in the effect of Earth's rotation, deflecting surface flow westward
Climate - prevailing weather pattern in a region
-Includes temperature, precipitation, wind, and light
- Climate determines the occurrence of different biomes - major community types
Climate: Convection Cells - - Based on warmth at equator causing air to rise and flow north and
south toward poles
- Air would cool and fall, flowing back to the equator
Climate: Major Biomes - - Determined by temperature differences and wind patterns
Adiabatic cooling - - increasing elevation leads to 10C drop for every 1,000m
Rain Shadow - Warm, moist air flows up mountain and cools releasing precipitation, leeward side
allows drier air to descend, forming area of low precipitation
Sea Breezes - - Cool daytime breezes in costal areas
- During the day, land heats up and air rises, pulling cool ocean air to replace it
- At night, land cools quicker than the sea and the pattern reverses- causes offshore breezes.
- The sea moderates costal and island temperatures
10 major terrestrial biomes - 1. Tropical rain forest
2. Tropical deciduous forest
3a. Temperate rain forest
, 3b. Temperate coniferous forest (taiga)
4. Temperate deciduous forest
5. Tropical grassland (savanna)
6. Temperate grassland
(prairie)
7. Hot desert
8. Cold desert
9. Tundra
10. Mountain ranges
Terrestrial biomes are classified according to physical factors - average annual precipitation and
temperature
Tropical Rain Forest - -230cm precip
-25o-29 C
-Soils shallow, nutrient poor
-100+ tree species/km2
-Vines, epiphytes common
-Diverse animal life
Insects, reptiles, amphib, mammals- large mammals rare
Tropical Deciduous Forest - -120-280 cm/yr precip
-25-39o C
-Understory grows when trees shed leaves
-Animal diversity high, monkeys, pigs, antelope, tigers
-Tropical Thorn forests contain more browsing mammals- hence develp of thorns on plants
Temperate Deciduous Forest - - 75-200 cm precip
- Winter -12 o C
