Weather 2 Flashcards
While operating around buildings, the Remote Pilot in Command should be aware of the creation of wind gusts that
1 enhance stability and imagery.
2 increase performance of an aircraft.
3 change rapidly in direction and speed causing turbulence.

You are flying near mountains, and there are lenticular clouds. What kind of weather should you expect?
1 very rough air/turbulence.
2 smooth weather.
3 snow showers.

What clouds have the greatest turbulence?
1 Nimbostratus.
2 Towering cumulus.
3 Cumulonimbus.

What situation is most conducive to the formation of radiation fog?
1 The movement of cold air over much warmer water.
2 Moist, tropical air moving over cold, offshore water.
3 Warm, moist air over low, flatland areas on clear, calm nights.
Warm, moist air over low, flatland areas on clear, calm nights.
What types of fog depend upon wind in order to exist?
1 Steam fog and ground fog.
2 Advection fog and upslope fog.
3 Radiation fog and ice fog.

An air mass moving inland from the coast in winter is likely to result in
1 frost.
2 rain.
3 fog.

What is meant by the term “dewpoint”?
1 The temperature to which air must be cooled to become saturated.
2 The temperature at which condensation and evaporation are equal.
3 The temperature at which dew will always form.
The temperature to which air must be cooled to become saturated.
In which situation is advection fog most likely to form?
1 A light breeze blowing colder air out to sea.
2 A warm, moist air mass on the windward side of mountains.
3 An air mass moving inland from the coast in winter.
An air mass moving inland from the coast in winter.
The amount of water vapor which air can hold depends on the
1 stability of the air.
2 dewpoint.
3 air temperature.
air temperature.
What cloud types would indicate convective turbulence?
1 Nimbostratus clouds.
2 Cirrus clouds.
3 Towering cumulus clouds.
Towering cumulus clouds.
The suffix “nimbus,” used in naming clouds, means
1 a rain cloud.
2 a cloud with extensive vertical development.
3 a middle cloud containing ice pellets.
a rain cloud.
Convective circulation patterns associated with sea breezes are caused by
1 warm, dense air moving inland from over the water.
2 water absorbing and radiating heat faster than the land.
3 cool, dense air moving inland from over the water.
cool, dense air moving inland from over the water.
Low-level turbulence can occur and icing can become hazardous in which type of fog?
1 Steam fog.
2 Upslope fog.
3 Rain-induced fog.
Steam fog.
