6 Multiple choice questions
- the temperature above freezing to which air must be cooled to reach saturation.
- a state in which the air is "holding" all of the water that it can take at a given temperature.
- a visible mass of water droplets or ice crystals that are suspended in an air layer that is NOT in contact with the ground.
- water droplets formed by condensation of water vapor on a relatively cold surfaces like grass, cars, etc.
- a visible mass of water droplets or ice crystals that are suspended in an air layer that has contact with the ground.
- the temperature below freezing to which air must be cooled to reach saturation.
6 True/False questions
Cold Front → a boundary in which a warm air mass is over taking a cold air mass.
Expansional Cooling → when air reaches saturation because it has been heated and it rises because it's density has been reduced.
Stationary Front → 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.
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.
Occluded Front → a boundary that forms when a cold front overtakes a warm front.
