Correct! Wrong!

Which weather phenomenon signals the beginning of the mature stage of a thunderstorm?

A. The appearance of an anvil top.

B. Precipitation beginning to fall.

C. Maximum growth rate of the clouds.

Correct! Wrong!

Steady precipitation preceding a front is an indication of

A. stratiform clouds with moderate turbulence.

B. cumuliform clouds with little or no turbulence.

C. stratiform clouds with little or no turbulence.

Correct! Wrong!

(Refer to Figure 19.) How are Significant Weather Prognostic Charts best used by a pilot?

A. For overall planning at all altitudes.

B. For determining areas to avoid (freezing levels and turbulence).

C. For analyzing current frontal activity and cloud coverage.

Correct! Wrong!

The boundary between two different air masses is referred to as a

A. frontolysis.

C. front.

Correct! Wrong!

A nonfrontal, narrow band of active thunderstorms that often develop ahead of a cold front is a known as a

A. prefrontal system.

B. squall line.

C. dry line.

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.

A. LIFR – visibility 0 to 1 statute mile.

B. IFR – visibility 0 to 1 statute mile.

C. MVFR – visibility 3 to 5 statute miles.

Correct! Wrong!
