PRACTICE SOLUTION GRADED A+

◉ Inversion (Atmospheric Stability). Answer: -Usually temperature
decreases with altitude


-Inversion occurs when temperature of air rises with altitude


-Temperature of air increases with altitude to a certain point; (Top of
Inversion acts as a Lid)


-If Relative Humidity is high it can create clouds, fog, haze, or smoke
resulting in diminished visibility


◉ Unstable Air. Answer: Often results in:


-Cumuliform clouds
-Rough air (turbulence)
-Showery precipitation
-Good visibility

,◉ Atmosphere Pressure (Barometric Pressure). Answer: -Stations
use 1" Hg (hectographs) for every 1000 ft of elevation above sea
level


-Measured in "Hg or Mb (millibars)


-Sea Level Pressure = 29.92" Hg/ standard 59'F or 1,013 mb


-1"Hg = 34 mb


-Typical Mb pressure is 950.0 - 1,040 mb


-All weather stations use Sea Level Pressure to provide reports


◉ Stable Air. Answer: -Strati form Clouds and Fog


-Continuous precipitation


-Smooth air


-Fir to Poor Visibility in haze and smoke

, ◉ Effects of Pressure on Density. Answer: -Pressure Up = Density Up


-Pressure Down = Density Down


-IF TEMPERATURE REMAINS THE SAME


◉ Relative Humidity. Answer: -Amount of Water Vapor contained in
the Atmosphere


-Expressed as a % of maximum amount of water vapor air can hold


-Varies with Temperature = Warm air holds more water vs. Cold air
holds less water


-Dry Air = 0% Humidity


-Wet Air = 100% Humidity (cannot hold any more water)


◉ Factors Affected by Performance. Answer: -Take off distance
-Landing distance
-Rate of climb
-Ceiling
