albedo
percent of solar radiation reflected by a surface.
atmospheric pressure
ratio of the weight of the air to the area of the surface to which it presses.
barometer
instrument that measures atmospheric pressure.
climate
general weather conditions over many years.
conduction
type of energy transfer in which vibrating molecules pass heat along to other vibrating molecules by direct contact.
doldrums
narrow zone of low air pressure at the equator characterized by weak and undependable winds.
electromagnetic spectrum
complete range of wavelenghts of radiation.
exosphere
layer of the atmosphere above the ionoshpere that merges with interplanetary space.
greenhouse effect
process by which the atmosphere traps infared rays over the earth's surface.
horse latitudes
subtopical high-pressure belt of air, around 30° latitude.
ionosphere
lower region of the thermosphere, at an altitude of 80 to 550 km.
jet streams
bands of high-speed, high-altitude westerly winds.
mesopause
upper boundary of the mesoshpehe marked by an increase in temperature.
mesosphere
coldest layer of the atmosphere that extends upwards from the stratosphere to an altitude of 80 km.
nitrogen cycle
process of which nitrogen moves from the air to the soil to animals and back to the air.
ozone
form of atmospheric oxygen that has three atoms per molecule.
polar easterlies
weak global winds located north of the 65° north latitude and south of the 65° south latitude that flow away from the poles.
standard atmospheric pressure
the atmospheric pressure measured at sea level; 760 mm of mercury.
stratopause
high-temperature zone that marks the upper boundary of the atmosphere.
stratosphere.
layer of the atmosphere that extends upward from the troposphere to an altitude of 50 km; contains most atmospheric ozone.
subpolar low
belt of low air pressure at about 60° north and 60° south latitude.
temperature inversion
atmospheric inversion in which warm air traps cooler air near the earth's surface.
thermosphere
the atmospheric layer obove the mesosphere.
trade winds
global winds flowing towards the equator between 30° and 0° latitude.
tropopause
upper boundary of the troposphere in which the temperature remains almost constant.
troposphere
atmospheric layer closet to the earth's surface where all weather occurs.
weather
genral condition of the atmosphere at a particlar time and place.
westerlies
global winds located between 40° and 60° latitude that flow from the southwest in the Northern hemisphere from the northwest in the southren temperature.
