FAA Private Pilot Weather Test 1
A nonfrontal, narrow band of active thunderstorms that often develop ahead of a cold front is a known as a
Correct!
Wrong!
Squall lines are bands of severe thunderstorms that tend to develop ahead of fast-moving cold fronts. These squall lines often contain severe steady-state thunderstorms. This is the single most intense weather hazard for aircraft. Answer A is incorrect because a squall line is a specific type of a prefrontal system. Answer C is incorrect because a dry line is a front across which there is seldom any significant air mass contrast other than moisture content.
The boundary between two different air masses is referred to as a
