6 Multiple choice questions
- the temperature below freezing to which air must be cooled to reach saturation.
- a temperature drop that accompanies a pressure reduction on an air parcel, as when air parcels rise within the atmosphere.
- when air reaches saturation because it has been heated and it rises because it's density has been reduced.
- a visible mass of water droplets or ice crystals that are suspended in an air layer that is NOT in contact with the ground.
- a nearly motionless boundary between a cold air mass and a warm air mass. Winds blow parallel to the front, but in opposite directions on the two sides of the front.
- a boundary that forms when a cold front overtakes a warm front.
6 True/False questions
Warm Front → a boundary in which a cold air mass is overtaking a warm air mass.
Frost → a boundary that exists between air masses with different temperatures and/or water vapor concentrations.
Steam Fog → a general name for a ground level cloud that forms when cold air comes in contact with relatively warm water.
Air Mass → a large volume of air with uniform temperature and water vapor concentrations.
Advection Fog → a ground level cloud formed by nighttime radiational cooling of a humid air layer. Common on clear nights with light winds over damp areas such as rain soaked fields or wetlands.
Cold Front → a boundary in which a cold air mass is overtaking a warm air mass.
