If the temperature/dewpoint spread is small and decreasing, and the temperature is 62 degrees F, what
type weather is most likely to develop? - fog or low clouds
How will frost on the wings of an airplane affect takeoff performance? - frost will disrupt the
smooth airflow over the wing, adversely affecting its lift capability
How does frost affect the lifting surfaces of an airplane on takeoff? - frost may prevent the
airplane from becoming airborne at normal takeoff speed
A pilot can expect a wind-shear zone in a temperature inversion whenever the wind speed at 2,000 to
4,000 feet above the surface is at least - 25 knots
A stable air mass is most likely to have which characteristic? - poor surface visibility
An almond or lens-shaped cloud which appears stationary, but which may contain winds of 50 knots or
more, is referred to as - a lenticular cloud
An increase in temperature with an altitude increase - is indication of an inversion
At approximately what altitude above the surface would the pilot expect the base of cumuliform clouds
if the surface air temperature is 82 degrees F and the dewpoint is 38 degrees F? - 10,000 feet AGL
Clouds are divided into four families according to their - height range
Clouds with extensive vertical development over mountainous terrain are a sign of - an unstable
air mass
Clouds, fog, or dew will always form when - water vapor condenses
, A nonfrontal, narrow band of active thunderstorms that often develop ahead of a cold front is known as
a- squall line
Convective circulation patterns associated with sea breezes are caused by - cool, dense air moving
inland from over the water
Crests of standing mountain waves may be marked by stationary, lens shaped clouds known as -
standing lenticular clouds
Cumulus clouds often indicate - possible turbulence
During the life cycle of a thunderstorm, which stage is characterized predominately by downdrafts? -
dissipating
Every physical process of weather is accompanied by, or is the result of, a - heat exchange
If an unstable air mass is forced upward, what type clouds can be expected? - clouds with
considerable vertical development and associated turbulence
If there is thunderstorm activity in the vicinity of an airport at which you plan to land, which hazardous
atmospheric phenomenon might be expected on the landing approach? - wind-shear turbulence
In which environment is aircraft structural ice most likely to have the highest accumulation rate? -
freezing rain
In which situation is advection fog most likely to form? - an air mass moving inland from the coast
in winter
Low-level turbulence can occur and icing can become hazardous in which type of fog? - steam fog
One in-flight condition necessary for structural icing to form is - visible moisture
