Unit 7 - weather Questions with Answers
Every physical process of weather is accompanied by, or is the result of, a
Ans: heat exchange
What causes variations in altimeter settings between weather reporting points?
Ans: Unequal heating of the Earth's surface.
The wind at 5,000 feet AGL is southwesterly while the surface wind is southerly.
This difference in direction is primarily due to
Ans: friction between the wind and the surface.
Convective circulation patterns associated with sea breezes are caused by
Ans: cool, dense air moving inland from over the water
the development of thermals depends upon
Ans: solar heating.
The boundary between two different air masses is referred to as a
Ans: front.
One weather phenomenon which will always occur when flying across a front is a
change in the
Ans: wind direction
One of the most easily recognized discontinuities across a front is
Ans: a change in temperature.
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?
Ans: wind-shear turbulence.
A nonfrontal, narrow band of active thunderstorms that often develop ahead of a
cold front is known as a
Q&A
, Ans: squall line
What conditions are necessary for the formation of thunderstorms?

Ans: Dissipating.
Thunderstorms reach their greatest intensity during the
Ans: mature stage
What feature is normally associated with the cumulus stage of a thunderstorm?
Ans: continuous updraft
Which weather phenomenon signals the beginning of the mature stage of a
thunderstorm?
Ans: precipitation beginning to fall.
Thunderstorms which generally produce the most intense hazard to aircraft are

Ans: lightning.
One in-flight condition necessary for structural icing to form is
Ans: visible moisture
In which environment is aircraft structural ice most likely to have the highest
accumulation rate?
Ans: Freezing rain.
The presence of ice pellets at the surface is evidence that there
Ans: is a temperature inversion with freezing rain at a higher altitude.
