Jeppesen Stage 2 Test Questions with Complete Answers Frost will disrupt the smooth flow of air over the wing, adversely affecting its lifting capability. Correct Answer How will frost on the wings of an airplane affect takeoff performance?
Heat exchange Correct Answer Every physical process of weather is accompanied by, or is the result of, a
An increase in temperature as altitude is increased Correct Answer A temperature inversion would most likely result in which weather condition?
Terrestrial radiation on a clear, relatively still night Correct Answer 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 Answer 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 Answer What is meant by the term "dewpoint"
Air temperature Correct Answer The amount of water vapor which air can hold depends on the
Water vapor condenses Correct Answer Clouds, fog or dew will always form when
Evaporation and sublimation Correct Answer 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 Answer What conditions result in the formation of frost?
Unequal heating of the Earth's surface Correct Answer What causes variations in altimeter settings between weather reporting points?
Friction between the wind and the surface Correct Answer 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 Answer Convective circulation patterns associated with sea breezes are caused by Is a temperature inversion with freezing rain at a higher altitude Correct Answer The presence of ice pellets at the surface is evidence that there
Actual lapse rate Correct Answer What measurement can be used to determine the stability of the atmosphere?
Warming from below Correct Answer What would decrease the stability of an air mass?
Stratiform clouds Correct Answer What is a characteristic of stable air?
Produce stratus type clouds Correct Answer Moist, stable air flowing upslope can be expected to
Clouds with considerable vertical development and associated turbulence. Correct Answer If an unstable air mass is forced upward, what type of clouds can be expected?
A stable layer of air Correct Answer What feature is associated with temperature inversion?
6,000 feet MSL Correct Answer 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 Answer 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 Answer What are the characteristics of a moist, unstable air mass?
Turbulence and good surface visibility Correct Answer What are the characteristics of unstable air?
Smooth air Correct Answer A stable air mass is most likely to have which characteristic?
A rain cloud Correct Answer The suffix "nimbus" used in naming clouds, means
Height range Correct Answer Clouds are divided into four families according to their
Front Correct Answer The boundary between two different air masses is referred to as a
