  1. ice crystals formed by sublimation of water vapor on a relatively cold surface like grass, cars, etc.
  2. a boundary that forms when a cold front overtakes a warm front.
  3. a general name for a ground level cloud that forms when cold air comes in contact with relatively warm water.
  4. when air reaches saturation because it has been heated and it rises because it's density has been reduced.
  5. a visible mass of water droplets or ice crystals that are suspended in an air layer that is NOT in contact with the ground.
  6. a temperature drop that accompanies a pressure reduction on an air parcel, as when air parcels rise within the atmosphere.

  2. Saturationa state in which the air is "holding" all of the water that it can take at a given temperature.

          

  3. Foga boundary that exists between air masses with different temperatures and/or water vapor concentrations.

          

  4. Orographic Liftingthe temperature below freezing to which air must be cooled to reach saturation.
