Key Terms
Albedo - the fraction of incident electromagnetic radiation reflected by a surface
antarctic circle - the latitude 66.5 degrees south
anticyclonic flow - the flow of air around a region of high pressure clockwise in the
Northern Hemisphere
arctic circle - the latitude 66.5 degrees north
autumnal equinox -the passage of the Sun across the equator as it moves from the
Northern Hemisphere into the Southern Hemisphere, approximately September 23.
During this time, all places in the world experience equal lengths of night and day. Also
called fall equinox
Climate - the meteorological conditions, including temperature, precipitation, and wind
that characteristically prevail in a particular region; the long-term average of weather
climate system - refers to all factors that influence the climate of a region, including both
natural and human-induced climate changes and their interactions
cold front - a weather front in which a cold air mass moves into and under a warm air
mass. It creates a narrow band of intense precipitation
convection cell - a circular-moving loop of matter involved in convective movement
Cyclones - an atmospheric system characterized by the rapid, inward circulation of air
masses about a low-pressure center that is associated with rising air. Cyclones circulate
counterclockwise in the Northern Hemisphere and clockwise in the Southern
Hemisphere and are usually accompanied by stormy, often destructive, weather
Declination - the angular distance of the Sun or Moon above or below the plane of
Earth’s equator
Doldrums - a global belt of light, variable winds near the equator, resulting from the
vertical flow of low density air masses upward within this equatorial belt. Associated with
much precipitation
Equatorial - pertaining to the equatorial region
equatorial low - a band of low atmospheric pressure that encircles the globe along the
equator
eye of the hurricane - a circular low-pressure area of relative calm at the center of a
hurricane
Faculae - a bright spot on the Sun that is associated with magnetic storms
feedback loops - a self-repeating processes in which an initial change is modified. A
positive-feedback loop amplifies an initial change, and a negative-feedback loop
counteracts an initial change
ferrel cell - the large atmospheric circulation cell that occurs between 30 and 60 degrees
latitude in each hemisphere
hadley cells - the large atmospheric circulation cell that occurs between the equator and
30 degrees latitude in each hemisphere
horse latitudes - the global belts between about 30 and 35 degrees north and south
latitude, where winds are light and variable as a result of the vertical movement of air
masses downward at these latitudes, causing a hot, dry climate. These belts are
associated with the major continental and maritime deserts of the world
