Question	Answer
every physical process of weather is accompanied by,or is the result of,a	heat exchange.
what causes variations in altimeter settings between weather report points?	unequal heating of the Earth's surface.
the wind at 5,000 feet AGL is Southwesterly while the surface wind is southerly, the difference in direction is primarily due to	friction between the wind and the surface.
convective circulation patterns associated with sea breezes are caused by	cool dance air moving in land from over the water.
the development of thermals depends upon	solar heating
the boundary between tow different air masses is referred to as a	front
one weather phenomenon which will always occur when flying across a front is a change in the	wind direction.
one of the most easily recognized discontinuities across the front is	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 ?	wind- shear turbulence
a non frontal narrow band of active thunderstorms that often develop ahead of a cold front is known as a	squall line.
what condition are necessary for the formation of thunderstorms?	high humidity, lifting force, and unstable condition.
during the life cycle of a thunderstorm, which stage is characterize predominantly by downdrafts?	dissipating.
thunderstorms reach their greatest intensity during the	mature stage.
what feature is normally associated with the cumulus stage of the thunderstorm?	continuous updraft.
Which weather phenomenon signals the beginning of the mature stage of a thunderstorm?	precipitation beginning to fall
Thunderstorms which generally produce the most intense hazard to aircraft are	squall line thunderstorms.
Which weather phenomenon is always associated with a thunderstorm?	lightning.
Why is frost considered hazardous to flight?	frost spoils the smooth flow of air over the wings, thereby decreasing lifting capacity.
How will frost on the wings of an airplane affect takeoff performance?	frost will disrupt the smooth flow of air over the wings, adversely affecting its lifting capacity.
How does frost affect the lifting surfaces of an airplane of takeoff?	frost may prevent the aircraft from becoming airborne at normal takeoff speeds.
