8 Sci Ch 7 Test 7

14.7 psi atmospheric pressure at sea level
adiabatic process in which the temperature of a gas rises as the gas is compressed with no heat lost
albedo the decimal equivalent of solar radiation that an object reflects
anabatic air flowing up a mountain's slope because of differences in temperature and pressure
anticyclone circulating spiral of wind around a high-pressure system
atmosphere blanket of gases that surrounds our planet
auroras scientific name for the northern and southern lights
cloud cover, length of daytime, angle of the sun's rays and Earth's distance from the sun four main factors that affect insolation
convection heat transfer by moving currents of hot air
cosmic rays very powerful radiation that comes from deep space
cyclone a circulating spiral of wind around a low-pressure system
energy budget term refers to the amount of energy available to heat the earth's land, water and air
exosphere outermost layer of the atmosphere
fall wind type of wind that occurs when dense, cold air flows from higher to lower elevations due to gravity
Ferrel cell Cell that moves air form 30 degrees to 60 degrees latitude
foehn a warm, dry wind that travels down a slope
greenhouse effect process that traps heat in the earth's atmosphere
Hadley cell a system of vertical and horizontal air circulation that creates major weather patterns, predominantly in tropical and subtropical regions
heterosphere upper atmosphere
homosphere lower layer of the atmosphere
horse latitudes regions of high pressure and gentle winds at 30° north and south latitude
ionosphere layer of the atmosphere that "bounces" certain types of radio waves back toward the ground
ITCZ equatorial zone where sailing ships were often left without wind
jet stream high-altitude wind in a narrow, meandering band
land breeze cool, gentle wind that blows from the land to the sea
magnetic field region in which a magnet affects other objects
magnetosphere part of the earth's magnetic field that is affected by the solar winds
mesopause coldest point in the atmosphere
mesosphere least understood layer of the atmosphere
monsoons winds that reverse their direction from season to season
nitrogen most abundant gas in the homosphere
ozone layer Protective layer in atmosphere that "shields" earth from UV radiation.
polar cell Weak circulation cell that occurs between 60 and 90 degrees latitude. It results from upper air masses moving northward and descending at the poles, while at the same time surface air flows south.
radiation heat transfer by electromagnetic waves
Rossby waves upper troposphere waves that a big part of making cyclones and anticyclones
Santa Ana very dry and often dusty Southern California winds
stratosphere strong, steady winds but few changes of weather
thermopause boundary of the upper thermosphere
thermosphere layer of the atmosphere known for high temperatures
trade winds surface winds that blow from high-pressure regions toward the equator
troposphere "weather layer"
UVB type of radiation that causes tanning and sunburn
UVC most powerful and dangerous form of UV radiation
Van Allen radiation belts belt like regions surround the earth and trap particles from the solar wind
water vapor most important greenhouse gas
winds horizontal movements of air
