Jon Ahlquist Chapter 5 Review Condensation Dew Fog and Clouds 10 5 2006 Fog and Clouds What is the dew point temperature What is a condensation nucleus How common are condensation nuclei What does it mean if a condensation nucleus is hygroscopic or hydrophobic What common substance is hygroscopic If hygroscopic condensation nuclei are present how low can the relative humidity be for condensation How does a dry haze look different from a wet haze What type of cloud is radiation fog Advection fog Advection radiation fog What is upslope fog Where does it occur What is steam fog What is the basis for naming clouds What are the types of low clouds Middle clouds High clouds Which clouds extend through a significant vertical distance Name the clouds in the following pictures Say as much about them as you can Tall cloud flat top Why is top flat Fig 5 22 p 125 Usually cover only small part of sky fig 5 13 p 120 Individual cloud puffs look like size of thumbnail when your arm is extended Fig 21 p 121 Lens shaped clouds downwind of mountains Sometimes confused with flying saucers like Fig 5 24 p 127 MET1010 Intro to the Atmosphere 1 Jon Ahlquist 10 5 2006 Glow of sun but no halo visible thru featureless cloud deck Fig 5 16 p 121 Wispy no sharply defined edges Fig 5 12 p 119 Featureless cloud blanket Sun not visible Fig 5 19 p 123 Low separated puffy clouds Fig 5 20 p 124 Featureless raining clouds not the small clouds i e scud Fig 5 17 p 122 Thin sheet often over whole sky Halo around sun or moon Fig 5 14 p 120 MET1010 Intro to the Atmosphere 2 Jon Ahlquist 10 5 2006 Clouds close together each about size of fist at arm s length Fig 5 18 p 122 Large clouds with cauliflower tops Fig 5 21 p 125 What causes cloud above mountain Fig 5 25 or on top of other cloud Fig 5 26 Clouds bulge downward Often seen on underside of cumulonimbus anvil Fig 5 27 p 128 Cloud ceiling Geostationary orbits Polar Orbits Radiometers To what does cloud ceiling refer Geostationary satellites how far from the Earth s surface are they is a geostationary orbit How much of the Earth can they see What parts of the Earth can they never see well Name two advantages of geostationary orbits over non geostationary orbits What problem does this orbit create for designing satellite sensors How many such satellites does the US keep in operation Where are they Roughly how far from the Earth s surface are they is a polar orbit How much of the Earth can they see at any one instant In one orbit In a day Are there any parts of the Earth they can t see well Name two advantages of a polar orbit over a geostationary orbit What Roughly What MET1010 Intro to the Atmosphere Polar orbiting satellites What is a radiometer Infrared IR photographs How does IR photography work is an advantage of IR photography over using regular visible light What 3 Jon Ahlquist 10 5 2006 Satellite Imaging and Vertical Profiling Clouds that appear bright in a visible satellite picture are thick clouds Why Clouds that appear bright in an infrared satellite picture are high clouds Why How is it possible for a satellite to sense what is going on at various levels of the atmosphere MET1010 Intro to the Atmosphere 4
