What are the percentages of gases in pure, dry air? - ANSWER 78%
nitrogen
21% oxygen
1% other gases
What percent is water vapor in the atmosphere? - ANSWER 0-5% by
volume
What is the troposphere? - ANSWER Layer adjacent to the Earth's
surface
Where does all weather occur? - ANSWER Troposphere
In the troposhpere, what happens to the temperature with an increase in
altitude? - ANSWER Temperature decreases
What are the winds like in the troposphere? - ANSWER Winds are light
near the Earths surface and increase with altitude
Where is the troposphere? (height) - ANSWER Average height of 36000
MSL
What is the moisture content in the troposphere? - ANSWER Large
amounts of moisture and condensation
Is the troposphere higher in the summer or in the winter? - ANSWER
Higher in the summer. Think that the air is heating up and rising the
troposphere
What is the tropopause? - ANSWER Transition zone between the
troposphere and stratosphere
What happens to temperature with an increase in altitude in the
tropopause? Decrease? - ANSWER Constant
,Constant
Where do the strongest winds occur? - ANSWER In the tropopause
What is atmospheric pressure? What is atmospheric pressure also known
as? - ANSWER Pressure exerted on a surface by the atmosphere due to
the weight of the column of air directly above that surface
As altitude increases, what happens to pressure? - ANSWER Decreases
always
What are the two standard units of pressure? - ANSWER Inches of
mercury (in-Hg)
Millibars (mb)
What is station pressure? - ANSWER Atmospheric pressure measured
directly at an airfield
Which is greater, station pressure or sea level pressure? - ANSWER
Station pressure...... stations wont be in the sea
What is Sea Level Pressure? - ANSWER Pressure that would be
measured if the station was at MSL
How do stations report pressure regardless of location? - ANSWER In
Sea Level Pressure
What is Atmospheric circulation? - ANSWER Earth is constantly heated
and cooled as it rotates. This causes ascending and descending air
What are the two ways atmospheric circulation moves air? - ANSWER
Ascending and descending currents
What causes Atmospheric circulation? - ANSWER Wind trying to go
from high pressure to low pressure. Due to the Coriolis Force
What are Pressure Gradients? - ANSWER Spacing of isobars that
represent a change in pressure over a horizontal distance.
When is a Pressure Gradient Force (PGF) strong? - ANSWER When
isobars are close together
, What is the initiating force for all winds? - ANSWER Pressure Gradient
Force
What pressure gradient force is associated with slower winds? -
ANSWER Wide spaced PGF
What is standard atmosphere? - ANSWER Standard day at sea level
conditions
29.92 in-Hg
15 C
What is Lapse rate? - ANSWER Decrease in atmospheric temperature
with increasing altitude
What is the average temperature lapse rate? - ANSWER 2C/1000ft
What is an isothermal lapse rate? - ANSWER Temperature is the same at
different altitudes
What is an air mass? - ANSWER Large body of air with uniform
temperature and moisture conditions in a horizontal plane
How are Air masses named? - ANSWER According to their location,
moisture content and temperature relative to the ground
What is Dew Point Temperature? - ANSWER Temperature at which
saturation occurs
What is dew point? - ANSWER direct indication of how much moisture
is in the air
What is dew point depression? - ANSWER Difference between the air
temperature and the dew point temperature
What is saturation? - ANSWER When the air contains the maximum
amount of moisture that it can hold for a certain temperature
What is Relative Humidity (RH)? - ANSWER The percent of saturation
in the air
Explain the effect a change in pressure has on the altimeter - ANSWER
"High to Low, Look out below"
