Ch 5

  1. The Earth's Atmosphere Subsystem...
    controls the absorption, and distribution of solar radiated energy.
  2. Climate is defined as...
    weather at a particular place averaged over a specific interval of time.
  3. What does absorption of solar radiation do the atmosphere?
    The radiation heats the atmosphere.
  4. Solar altitude is the?
    angle of the sun above the horizon and varies from 0 degrees to as much as 90 degrees.
  5. Latent heat is also transferred from ocean water to the atmosphere through?
  6. Daylight is shortest during the...?
    Winter solstice
  7. Daylight is longer during the?
    Summer Solstice
  8. With Scattering....
    Particles disperse radiation in all directions.
  9. What can scatter solar radiation?
    Tiny water droplets, and ice crystals that compose clouds.
  10. Why is the sky blue?
    Because of scattering of solar radiation over water droplets and ice crystals that are in the atmosphere.
  11. Why do our eyes see blue in the sky?
    Visible sunlight is made up of all colors, from violet at the short wavelength end of the solar spectrum to red at the long wavelength end. Air molecules preferentially scatter short wavelength visible light, blue-violet causing it to enter the observers eyes from many different directions.
  12. Reflection is...
    a special case of scattering in which a large surface area redirects radiation in a backward direction.
  13. Albedo is...
    Usually, albedo refers to radiation in the visible range or to the full spectrum of solar radiation.
  14. Absorption is..
    a process where some of the radiation that strikes an object is converted to heat energy. (Oxygen, ozone, water vapor, and various aerosols absorb solar radiation)
  15. Planetary albedo is..
    when the atmosphere reflects or scatters back to space the solar radiation. (about 31%)
  16. The Photic Zone is the?
    sunlit surface layer of the ocean, down to the depth where light is just sufficient for photosynthesis.
  17. The Autumnal Equinox is...
    in the northern hemisphere, The beginning of fall, when light and dark are equal.
  18. Vernal Equinox is
    the beginning of spring when day and light are equal
  19. Weather...
    State of the atmosphere at a given place at a given time.
  20. Global radiative equilibrium...
    Keeps the planet's temp in check to some extent. Emission of heat to space in the form of infrared radiation balance solar radiation heating of the atmosphere system.
