Aviation Meteorology || All Answers Are Correct 100%.
Convert 15 degree Celsius to Fahrenheit temperature. correct answers 59F
standard lapse rate is about ______ degrees C per 1000 feet. correct answers 2
The most frequent type of ground or surface based temperature inversion is that which is
produced by correct answers the movement of colder air under warm air, or the movement of
warm air over cold air
Moisture is added to air by correct answers Evaporation and sublimation
T/F
Relative humidity indicate the actual water contents instead of how close the air is to saturation,
so relative humidity is always constant regardless of temperature. correct answers FALSE
T/F
The higher the air parcel's temperature is, the greater the air parcel's capacity of holding water
will be. correct answers TRUE
Assuming constant pressure, temperature, and volume, which statement is correct?
-air with greater amount of water vapor is more dense (weigh more) than air with lesser amount
of water vapor.
-air with greater amount of water vapor is less dense (weigh less) than air with lesser amount of
water vapor
-air with greater amount of water vapor has same density (weigh same) as air with lesser amount
water vapor. correct answers air with greater amount of water vapor is less dense (weigh less)
than air with lesser amount of water vapor
A temperature inversion would most likely result in which weather condition ? correct answers
An increase in temperature as altitude is increased
The difference between an air parcel's temperature and its dewpoint is the dewpoint depression,
or commonly referred to as the spread.
When the spread decreases to zero : correct answers relative humidity is 100 percent
Select the phase transition that is not associated with the absorption of latent heat:
melting
evaporation
sublimation
freezing correct answers FREEZING
What is incorrect statements about density
-Assuming equal mass, an air parcel with a higher density has a smaller volume than an air
parcel with a lower density
, -Assuming constant mass and temperature, an air parcel with a higher pressure is denser than an
air parcel with a lower pressure.
-Assuming constant mass and pressure, an air parcel with a higher temperature is less dense than
an air parcel with a lower temperature
-Assuming constant pressure, temperature, and volume, air with a greater amount of water vapor
is more dense than air with a lesser amount of water vapor. correct answers Assuming constant
pressure, temperature, and volume, air with a greater amount of water vapor is more dense than
air with a lesser amount of water vapor.
T/F
In the cold air column, the pilot would fly at an altitude lower than the indicated altitude. correct
answers TRUE
Every physical process of weather is accompanied by, or is the result of, a correct answers Heat
exchange
Clouds, fog, or dew will always form when correct answers water vapor condenses
Which is true regarding actual air temperature and dewpoint temperature spread? the temperature
spread correct answers decreases as the relative humidity increases.
T/F
On Density altitude - dewpoint (water vapor) is also contributing factor, but its effects are
generally negligible. correct answers FALSE
The wind at 5,000 feet AGL is southwesterly while the surface wind is southerly. The difference
in direction is primarily due to correct answers friction between the wind and the surface
The performance table of an aircraft for takeoff and climb are based on correct answers
pressure/density altitude
Convective circulation patterns associated with sea breezes are caused by correct answers Cool,
dense air moving inland from over the water
Select incorrect statement.
-Cold Front - colder air replace warm air
-Warm Front - warmer air is replaced by colder air
-Stationary Front - a front which is stationary or near so
-Occluded Front - A composite of two front as a cold front takes a warm front or stationary front
correct answers Warm Front - warmer air is replaced by colder air
One weather phenomenon which will always occur when flying across a front is a change in the
correct answers PRESSURE
Select incorrect statement
-Warm fronts typically have a gentle slope
