NIFE WEATHER || 100% ERRORLESS ANSWERS.
What are the percentages of gases in pure, dry air? correct answers 78% nitrogen
21% oxygen
1% other gases
What percent is water vapor in the atmosphere? correct answers 0-5% by volume
What is the troposphere? correct answers Layer adjacent to the Earth's surface
Where does all weather occur? correct answers Troposphere
In the troposhpere, what happens to the temperature with an increase in altitude? correct answers
Temperature decreases
What are the winds like in the troposphere? correct answers Winds are light near the Earths
surface and increase with altitude
Where is the troposphere? (height) correct answers Average height of 36000 MSL
What is the moisture content in the troposphere? correct answers Large amounts of moisture and
condensation
Is the troposphere higher in the summer or in the winter? correct answers Higher in the summer.
Think that the air is heating up and rising the troposphere
What is the tropopause? correct answers Transition zone between the troposphere and
stratosphere
What happens to temperature with an increase in altitude in the tropopause? Decrease? correct
answers Constant
Constant
Where do the strongest winds occur? correct answers In the tropopause
What is atmospheric pressure? What is atmospheric pressure also known as? correct answers
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? correct answers Decreases always
What are the two standard units of pressure? correct answers Inches of mercury (in-Hg)
Millibars (mb)
What is station pressure? correct answers Atmospheric pressure measured directly at an airfield
, Which is greater, station pressure or sea level pressure? correct answers Station pressure......
stations wont be in the sea
What is Sea Level Pressure? correct answers Pressure that would be measured if the station was
at MSL
How do stations report pressure regardless of location? correct answers In Sea Level Pressure
What is Atmospheric circulation? correct answers Earth is constantly heated and cooled as it
rotates. This causes ascending and descending air
What are the two ways atmospheric circulation moves air? correct answers Ascending and
descending currents
What causes Atmospheric circulation? correct answers Wind trying to go from high pressure to
low pressure. Due to the Coriolis Force
What are Pressure Gradients? correct answers Spacing of isobars that represent a change in
pressure over a horizontal distance.
When is a Pressure Gradient Force (PGF) strong? correct answers When isobars are close
together
What is the initiating force for all winds? correct answers Pressure Gradient Force
What pressure gradient force is associated with slower winds? correct answers Wide spaced PGF
What is standard atmosphere? correct answers Standard day at sea level conditions
29.92 in-Hg
15 C
What is Lapse rate? correct answers Decrease in atmospheric temperature with increasing
altitude
What is the average temperature lapse rate? correct answers 2C/1000ft
What is an isothermal lapse rate? correct answers Temperature is the same at different altitudes
What is an air mass? correct answers Large body of air with uniform temperature and moisture
conditions in a horizontal plane
How are Air masses named? correct answers According to their location, moisture content and
temperature relative to the ground
What is Dew Point Temperature? correct answers Temperature at which saturation occurs
What are the percentages of gases in pure, dry air? correct answers 78% nitrogen
