Commercial Aviation Weather Exam
Questions and Answers|2025 Update
Rated A+
The formation of either predominantly stratiform or predominantly cumuliform clouds is
dependent upon the? - Answer- Stability of the air being lifted.
Which type of jetstream can be expected to cause the greater turbulence? - Answer- A
curving jetstream associated with a deep low-pressure trough.
Which cloud types would indicate convective turbulence? - Answer- Towering cumulus
clouds.
Ice pellets encountered during flight normally are evidence that? - Answer- A warm front
is about to pass.
During an approach, the most important and most easily recognized means of being
alerted to possible wind shear is monitoring the? - Answer- Power and vertical velocity
required to remain on the proper glidepath.
Which conditions are favorable for the formation of a surface based temperature
inversion? - Answer- Clear, cool nights with calm or light wind.
What prevents air from flowing directly from high-pressure areas to low-pressure areas?
- Answer- Coriolis force.
Which would increase the stability of an air mass? - Answer- Cooling from below.
What lifts advection gog into low stratus clouds? - Answer- Surface winds of
approximately 15 knots or stronger.
If clouds form as a result of very stable, moist air being forced to ascend a mountain
slope, the clouds will be? - Answer- Stratus type with little vertical development and little
or no turbulence.
Virga is best described as? - Answer- Streamers of precipitation trailing beneath clouds
which evaporates before reaching the ground.
What is indicated if ice pellets are encountered at 8,000 feet? - Answer- Freezing rain at
higher altitude.
The presence of standing lenticular altocumulus clouds is a good indication of? -
Answer- Very strong turbulence.
