Climate Flashcards
Weather vs Climate?
weather->over a short period of time
climate->over a long period of time
What is the most important factor that determines climate
heat budget
2 ways ocean affects climate?
- Ocean currents
2. Nearness to ocean
how is the temperature of a region affected by latitude altitude and distance from ocean?
latitude: higher the latitude colder the temperature
altitude: higher the altitude decrease in temperature
distance from ocean: closer to ocean more moderate temp
what is a rain shadow and how does it form?
a rain shadow is a sheltered area on a mountain that does not receive prevailing winds that bring clouds and rain. (leeward side)
windward side vs leeward side
windward: traps moisture
leeward: dry, side away from mountain
2 influences on precipitation:
prevailing winds
topography
main causes for climate?
elevation: as elevation increases, temp decreases
ocean currents: warm east coast cool west coast
topography: windward sides of mtns are cooled and receive more precipitation, leward sides are warmed
nearness to large bodies of water: near to water, more moderate temperatures, higher precipitation especially on leeward side of water
key factors that effect climate in golden?
elevation
topography
Possible causes of climate change?
plate tectonics
-changes in the positions of the continents may affect wind patterns, ocean currents, solar energy
volcanoes
-dust and ash reflect solar radiation and provide condensation nuclei
human activity
milankovitch cycles:
climate change is related to changes in earths motions
prevailing wind direction:
determines windward and leeward sides of mountain ranges and oceans
polar cell:
Ferrell cell:
Hadley cell:
p: between top and 60 degrees N and S
f: 60 degrees N/S and 30 degrees N/S
h: 30 degrees N/S and equator
Coriolis effect
•earth is spinning •the air and water are not directly attached •an object is pushed but deflected -to the right in northern hemispheres -to the left in Southern Hemisphere
major currents in the northern Hemisphere rotate:
major currents in the Southern Hemisphere rotate:
clockwise
counterclockwise
