Weather Basics
This instrument measures atmospheric preasure
Barometer
This aviation weather report gives current conditions at an airport
METAR
These clouds are usually fluffy and have a flat looking base
Cumulus
Wind is caused primarily by differences in this
Air preasure
Thunderstorms require moisture, instability, and what
Lift
This is the temperature at which air becomes saturated and water vapor begins to condense
Dew Point
This forecast describes expected weather at an airport
TAF
This cloud type is associated with widespread stead precipitation and often covers much of the sky
cumulonimbus
A wind reported as 270 15 knots is coming from what direction
West
This weather phenomenon produces lightning and thunder
Thunderstorm
When temperature and dew point get very close together, this becomes more likely
Fog
In the METAR, 10SM means this
10 Statute Miles
Clouds for when air rises and cools to its
Dew Point
This wind condition occurs when wind speed or direction changes significantly over a short distance
Wind Shear
Hail can be especially dangerous to aircraft because it can damage his part of the plane
Engine, prop, Wings, Windshield
Air preasure generally decreases as this increases
Altitude
A ceiling below 1000 ft or visibility below 3 SM miles creates what conditions
IFR
This cloud can produce several turbulence, hail, lightning and tornadoes
cumulonimbus
If a runway is oriented 09/27 and wind is coming almost directly from this runways direction
Flying through this type of cloud is generally hazardous
Cumulonimbus
This standard atmosphere assumes sea level pressure of approx this value
29.92

18012G20KT
12 gust 20 knots
A pilot sees towering cumulus clouds rapidly growing vertically. This is a warning sign that this may be developing
Thunderstorms
A sudden increase in wind speed, often associated with thunderstorms is called this
microburst
This dangerous downdraft associated phenomenon can cause rapid changes in wind direction and speed near the ground
