Jeppesen Stage 2 Test || with Answers.
Frost will disrupt the smooth flow of air over the wing, adversely affecting its lifting
capability. correct answers How will frost on the wings of an airplane affect takeoff
performance?
heat exchange correct answers Every physical process of weather is accompanied by, or is the
result of, a
an increase in temperature as altitude is increased correct answers A temperature inversion
would most likely result in which weather condition?
terrestrial radiation on a clear, relatively still night correct answers The most frequent type of
ground or surface-based temperature inversion is that which is produced by
smooth air, poor visibility, fog, haze, or low clouds correct answers Which weather
conditions should be expected beneath a low-level temperature inversion layer when the
relative humidity is high?
The temperature to which air must be cooled to be saturated. correct answers What is meant
by the term "dewpoint"
Air temperature correct answers The amount of water vapor which air can hold depends on
the
water vapor condenses correct answers Clouds, fog or dew will always form when
Evaporation and sublimation correct answers What are the processes by which moisture is
added to saturated air?
The temperature of the collecting surface is at or below the dewpoint of the adjacent air and
the dewpoint is below freezing correct answers What conditions result in the formation of
frost?
unequal heating of the Earth's surface correct answers What causes variations in altimeter
settings between weather reporting points?
friction between the wind and the surface correct answers The wind at 5,000 feet AGL is
southwesterly while the surface wind is southerly. This difference in direction is primarily
due to
cool, dense air moving inland from over the water. correct answers Convective circulation
patterns associated with sea breezes are caused by
is a temperature inversion with freezing rain at a higher altitude correct answers The presence
of ice pellets at the surface is evidence that there
actual lapse rate correct answers What measurement can be used to determine the stability of
the atmosphere?
, warming from below correct answers What would decrease the stability of an air mass?
stratiform clouds correct answers What is a characteristic of stable air?
produce stratus type clouds correct answers Moist, stable air flowing upslope can be expected
to
Clouds with considerable vertical development and associated turbulence. correct answers If
an unstable air mass is forced upward, what type of clouds can be expected?
a stable layer of air correct answers What feature is associated with temperature inversion?
6,000 feet MSL correct answers What is the approximate base of the cumulus clouds if the
surface air temperature at 1,000 feet MSL is 70 degreesF and the dewpoint is 48degrees F?
10,000 feet AGL correct answers 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?
Cumuliform clouds and showery precipitation correct answers What are the characteristics of
a moist, unstable air mass?
turbulence and good surface visibility correct answers What are the characteristics of unstable
air?
smooth air correct answers A stable air mass is most likely to have which characteristic?
a rain cloud correct answers The suffix "nimbus" used in naming clouds, means
height range correct answers Clouds are divided into four families according to their
front correct answers The boundary between two different air masses is referred to as a
a change in temperature correct answers One of the most easily recognized discontinuities
across a front is
wind direction correct answers One weather phenomenon which will always occur when
when flying across a front is a change in the
stratiform clouds with little or no turbulence correct answers Steady precipitation preceding a
front is an indication of
Warm, moist air over low, flatland areas on clear, calm nights correct answers What situation
is most conducive to the formation of radiation fog?
fog or low clouds correct answers If the temperature/dewpoint spread is small and decreasing,
and the temperature is 62 degrees F, what type weather is most likely to develop?
an air mass moving inland from the coast in winter correct answers In which situation is
advection fog most likely to form?
