Exam 2 Flashcards
El Niño
Warm ocean current come down to North to replace cold ocean current; Bad due to no fish = no birds = no fertilizer = no wind = no rain
Most energy reradiate by Earth in this wave. Wavelengths range from 5.0 to 30 microns.
Longwave Energy
Used in South America
Vertical Climate Zones
Desert Climate (Bw)
Receives <250 mm/yr of rain.
Tierra Fria
(6000-10000ft) Cooler: potatoes, cereals, and vegetables.
Winters cold, summers very warm. Precipitation year-round, but harvest in summer. Winter precipitation is mostly snow.
Humid Continental (Dfa)
June 20 or 21 where the sun is directly overhead at noon.
Summer Solstice
On the western margins of continents. Precipitation is seasonal and caused by northward and southward movement of the subtropical high pressure zones.
Mediterranean (Cs)
Tropic of Capricorn
23.5º South Latitude
Warm Front
Warm air slides on top of cold air causing warm air to lose pressure and forming clouds. (Causes days of precipitation).
Vertical Climate Zones
Used in South America
Humid Tropical (Af)
Lie mostly withing 20º N and S of the equator. Rainy ITCZ, around 1600 mm/yr.
Plates that were separated from a very early supercontinent that moved around the continents that we know today.
Tectonic Plates
Longwave Energy
Most energy reradiate by Earth in this wave. Wavelengths range from 5.0 to 30 microns.
Tierra Helada
(Above 14000ft) Above the snow line: ice caps.
Mid Latitude Warm (C)
Variation season influences temperature. In Winter, life becomes restricted to organisms that can tolerate freezing conditions. Annual precipitation and evapotranspiration are generally less than mid-latitude climates. Influenced by the polar font.
Has enough moisture to support such vegetation and typically lies in transitional areas between desert and more humid regions.
Semiarid Climate (BS)
Orographic Precipitation
Wind forces air up and over mountains.
Most energy arriving front the Sun is shortwave. Wavelengths range from 0.2 to 5.0 microns.
Shortwave Energy (Insolation)
The angle at which solar radiation strikes a particular place at any point in time.
Angle of Incidence
Variation season influences temperature. In Winter, life becomes restricted to organisms that can tolerate freezing conditions. Annual precipitation and evapotranspiration are generally less than mid-latitude climates. Influenced by the polar font.
Mid Latitude Warm (C)
23.5º North Latitude
Tropic of Cancer
Summer temps are warm because long days and high solar angles cause more radiation in a day than tropical locations receive.
Mid Latitude Cold (D)
Wind forces air up and over mountains.
Orographic Precipitation
Moderated by ocean temperatures. Typical summer temps are 60-77ºF. Stay green all year. Cyclones occur in the winter.
Marine West Coast (Cfb)
Mediterranean (Cs)
On the western margins of continents. Precipitation is seasonal and caused by northward and southward movement of the subtropical high pressure zones.
Tropic of Cancer
23.5º North Latitude
Glaciers
Mountains of moving ice.
Distinct wet and dry season, wet season caused by the ITCZ.
Seasonal Humid Tropical (Aw)
Formed by heat and pressure. Metals & gemstones Shale -> Slate Limestone -> Marble Coal -> Diamond Sandstone -> Quartzite
Metamorphic Rocks
Change in direction of object’s path due to Earth’s rotation.
Coriolis Effect
Winds exceeding 119 km/h in the Northwestern Pacific
Typhoons
Outwash Plain
The downward slopping plane from a moving glacier. In front of the moraine
January - moves south toward tropic of capricorn mainly over land July - moves north towards the tropic of cancer over land
Intertropical Convergence Zone (ITCZ)
Summer Solstice
June 20 or 21 where the sun is directly overhead at noon.
The blockage of outgoing long wave energy causes Earth;s atmosphere to heat.
Greenhouse Effect
Warm air slides on top of cold air causing warm air to lose pressure and forming clouds. (Causes days of precipitation).
Warm Front
Cold Front Map Symbol
Blue lines with triangles
.
Extreme form of weather created when energy conditions in the atmosphere are such, that extremely intense convection occurs.
Tornadoes
(10000-14000ft) Above the tree line: grazing.
Puna
Autumnal Equinox
September 22 or 23. The perpendicular rays of the sun strike the equator, and the sun is directly overhead at the equator.
Typhoons
Winds exceeding 119 km/h in the Northwestern Pacific
General Circulation
Winter Solstice
December 21 or 22 at noon where the sun is directly overhead of places along the Tropic of Capricorn.
Volcanoes
Surface vent where lava emerges; Magma: inside (molten rock); Lava: once it has emerged from inside
Puna
(10000-14000ft) Above the tree line: grazing.
Over 3 km thick cover vast areas of Greenland and Antarctica.
Continental Glaciers
Humid Continental (Dfa)
Winters cold, summers very warm. Precipitation year-round, but harvest in summer. Winter precipitation is mostly snow.
U-shaped Valleys
Alpine glacier flows through a V-shape valley and it scours away from the rocks and rebounds the bottom. When the ice melts, the U-shaped valley remain, surrounding the knife-edge ridges.
Lie mostly withing 20º N and S of the equator. Rainy ITCZ, around 1600 mm/yr.
Humid Tropical (Af)
Centers of low pressure that develop along the polar front.
Cyclones
Condensation
Conversion from vapor to liquid state.
(3000ft-6000ft) More temperate zone: coffee, citrus fruits, field crops.
