At what stage(s) in the life cycle
of a thunderstorm should you expect
updrafts to occur from below the
base to the top of the cloud?
1.
The cumulus stage
2.
The mature stage
3.
The dissipating stage
4.
Throughout all stages
The least severe turbulence
associated with thunderstorms is
generally found at what location?
1.
Near the top of the cloud
2.
Near the base of the cloud
3.
Near the freezing level
4.
1500 ft above the freezing
level
Hail is associated with the mature
stage of a thunderstorm and is
found with the greatest frequency
between which levels?
1.
The surface and
5,000-ft level
2.
The
5,000- and 10,000-ft level
3.
The 10,000- and 15,000-ft level
4.
The 15,000- and 20,000-ft level
When the intensities of turbulence
and precipitation are compared,
what relationship should be
assumed?
1.
Turbulence intensity varies
inversely with precipitation
intensity
2.
Turbulence intensity varies
directly with precipitation
intensity
3.
The relationship between
turbulence and precipitation
intensities is dependent on the
size of the thunderstorm
4.
Turbulence intensity is not
related to precipitation
Which of the following activities
produces electrical charges in
cumulonimbus clouds?
1.
Raindrops falling through the
cloud produce static charges
2.
The passage of another cloud
with opposite polarity
3.
A cloud passing in the vicinity
of a high electrical field of
opposite polarity
4.
Opposite polarity within the
cloud relative to the earth’s
surface

In what area of a thunderstorm does
lightning most frequently occur?
1.
Immediately beneath the storm
2.
In areas with temperatures in
the range of 0°C to -9°C
3.
Within the “anvil” atop the
cumulonimbus cloud
4.
At the trailing edge of the
thunderstorm
What is the primary in-flight
hazard associated with lightning?
1.
Injury to personnel
2.
Discomfort for personnel
3.
Damage to radio equipment
4.
Damage to aircraft structural
components
Severe turbulence in thunderstorms
is most frequently encountered
within what stratum?

out at the base of a thunderstorm
as a result of downdrafts may
develop into which of the following
features?
1.
A small low-pressure area
2.
A small high-pressure area
3.
A squall line
4.
A microscale thunderstorm
