The Atmosphere Flashcards
Dominant component
Water vapor
Aerosols
Ozone
Carbon dioxide
Environmental Lapse rate
The temperature decrease in the troposphere
Atmospheric changes in temperature and pressure
Air pressure: always decreases with altitude
Temperature: varies from each atmospheric layer
Atmospheric layers
1)Troposphere Closest to earth All weather occurs Steady decrease in temperature 2) Stratosphere Steady temperature near bottom, but increase toward upper limit 3) Mesosphere Brastil decrease in temperature 4) Thermosphere Increase in temperature Very low density
Radiation
energy emitted from central source
Laws Governing Radiation
All objects emit radiation
Hotter objects emit more radiation than cooler objects
The hotter the object, the shorter the wavelength of radiation being emitted
Objects that are good emitters of radiation are good absorbers of radiation
Conduction
Energy transferred thought molecular interaction
Convection
Warm material migrating into cool material
Paths of incoming solar radiation
Scattering Break up and dispersion of radiation Atmosphere scatters blue radiation Reflection Radiation bouncing off a surface Lighter objects reflect more, and darker object reflect less Absorption Energy transferred to the internal molecular motion of an object
Albedo
Lighter objects reflect more, and darker object reflect less
