  1. Saturation
    condensation on a flat surface of pure water
  2. pressure of the water vapor (saturation vapor pressure)
    6.11 MB or .180
  3. vapor pressure (e)
    vapor represents the actual amount of water vapor in the air
  4. relative humidity
    (vapor pressure/saturated vapor pressure) x 100%
  5. ways to saturate the air
    • 1)bring moisture into an area
    • 2)cool it without changing water vapor content
    • 3)evaporating water into air to achieve saturation
  6. e(s)
    capacity of the air to hold water vapor at saturation
  7. T(D)
    air temp at saturation method 2
  8. wet bulb temperature
    air temp at saturation by method 3
  9. upper air instruments
    • 1.kites and captive balloon
    • 2.mountain observatory 
    • 3.manned balloons
    • 4.unmanned balloons
    •     -pilot balloon (V)
    •     -radiosonde balloon (T, p, r.h, v)
    • 5.satellites
    • 6.rockets (V)
    • 7.aircrafts
    •     -commercial (height, wind)
    •     -reconnaissance (T, p, r.h, v)
    • 8.new technology 
    •     -wind profilers, acoustic sounders, doppler radar
  10. cloud
    an aggregate of minute water drops/ice crystals suspended in air
  11. formation
    moisture is lifted to lower pressure, expands, and cools to saturation. condensation follows
  12. stable
    displaced object returns to its original position
  13. unstable
    displaced object accelerates away from original position
  14. neutral
    displaced object stays in its displaced position
  15. cloud classification based on
    • 1.stability
    • 2.height of cloud base above the surface
  16. high clouds
    • 1. cirrus
    • 2. cirrostratus 
    • 3. cirrocumulus
  17. middle clouds
    • 1. altostratus 
    • 2.altocumulus
    •     -castellantus
    •     -altocumulos floccus
    •     -lenticularis 
    •     -billow
  18. low clouds
    • 1. stratus
    • 2. cumulus
    • 3. stratocumulus
    • 4. nimbostratus
    • 5. cumulonimbis
  19. fog
    a cloud which forms at the ground
  20. Classification of fog by particle type
    • 1. ice crystals
    • 2. supercool 
    • 3. warm water
  21. process of formation (cold surface)
    • 1. radiation (most common)
    • 2. advection (motion by the wind)
    • 3. upslope
    • 4. barametric (pressure falls over moist air)

    • warm wet surface
    • 5. evaporation fog (steam)
    • 6. rain (warm, wet surface)

    7. mixing fog (moist/warm + moist/cool = mild saturated)
  22. e
    vapor pressure of the actual amount of water vapor in the air (absolute humidity) and which is represented by T(d)
  23. e(s)
    saturation vapor pressure representing the maximum amount of water (capacity of the air) vapor that the air can hold. It depends only on T
  24. salt effect
    effect of condensation nuclei that are hygroscopic (attract water vapor) - table salt
