Air Masses
The three factors that determine weather in an air mass
What is moisture content, cooling process, and stability?
A front
What is a transition zone between two air masses?
What is poor/restricted visibility?
Why should pilots avoid squall lines?
What is violent weather/turbulence/lightning/hail?
Maritime meaning
What is formed over water/moist air?
Type of air mass that is usually dry
What is continental air mass?
Air mass that undercuts the other in a cold front
What is cold air?
Clouds produced by cold fronts
What is towering cumulus/cumulonimbus
Front type that commonly causes icing in winter
What are warm fronts?
Continental meaning
What is formed over land/dry air?
Type of cloud that stable air usually produces
What are stratus clouds?
Mnemonic that helps remember warm front cloud order
What is C-CANS?
Weather commonly following a cold front
What is rapid clearing and temperature drop?
Freezing rain in a warm front is caused by
What is rain falls through subfreezing cold air?
Trowal meaning
What is wedge-shaped warm air in an occluded front?
Type of cloud associated with unstable air
What are cumulus/cumuliform clouds?
Occluded front
What is cold front overtaking warm front?
Common precipitation hazard in winter warm fronts
What is freezing rain/icing
Occlusion that is more likely to produce severe turbulence
What is cold occlusion?
What is movement over a colder surface causing cooling?
Two characteristics of cold air masses
What is turbulence, instability, good visibility, cumuliform clouds, showers/thunderstorms
Stationary front
What is a front where neither air mass advances?
Weather associated with stationary fronts
What is continuous drizzle and low clouds
Upper fronts are dangerous in winter because
What is freezing rain and icing
Warm front symbol looks like what
Red line with semicircles
