APES climate change vocab Flashcards
(32 cards)
Troposphere
Bottom layer of the atmosphere. Provides air.
Atmosphere
The layer of gases that surrounds the Earth.
Stratosphere
The layer above the troposphere.
Ozone layer
A portion of the Stratosphere above sea level
Convective circulation
Warm air rises, making vertical currents. Air regions into regions of lower atmospheric pressure, and expands and cools. Descends and becomes more dense, replaces warm air rising. Picks up heat and moisture and begins to rise again .
Weather
Specifies atmospheric conditions over short periods of time.
Climate
Describes atmospheric conditions across large geographic regions over long periods of time.
Temperature (thermal) inversion
The departure of the normal temp. profile when a layer of cool air occurs under a layer of warm air.
Convective cells
When density difference occurs within a body of liquid or gas.
Coriolis effect
Currents of convective cells appear to be deflected from a straight path as some portions of the globe beneath them move more quickly than others.
Greenhouse gas
Mostly human-made gases which tend to absorb infrared radiation effectively
Greenhouse effect
Some re emitted energy travels back toward the surface, warming it.
Aerosols
Microscopic droplets and particles
Milankovitch cycle
Variations in Earth’s rotation, which alters the way solar radiation is distributed on the surface.
Solar output
Radiation given off by the sun
Ocean absorption
The ocean absorbs carbon dioxide when the gas dissolves directly in water.
Ocean circulation
Ocean exchanges heat with the atmosphere, ocean currents move energy from place to place.
Paleoclimate
Climate in the geological past
IPCC
Intergovernmental panel on climate change
Thermohaline circulation
A worldwide current system. Warmer, fresher water moves along the surface and colder, saltier water (denser) moves deeper below.
El Niño southern oscillation
A systematic shift in atmospheric pressure, sea surface temperature, and ocean circulation in the tropical Pacific ocean.
Anthropogenic climate change
Increased air and ocean temperatures, altered rainfall and ENSO patterns.
Mitigation
Reduce greenhouse gas emissions
Adaptation
Find ways to cushion from blows.
