Unit 5 part 1
Condensation
moving from gas to liquid. "condensation on a glass"
Cumulus clouds
puffy white clouds that tend to have flat bottoms
Middle-level clouds
range from 6,500 AGL up to 20,000 feet AGL.
Fracto clouds
these clouds have irregular patterns, appearing like torn pieces of cotton candy. Strong winds rip them from larger clouds
ambient
Average-the ambient air temperature
longitude
Distance east or west of the prime meridian, measured in degrees
Greenwich MeanTime (GMT)
Greenwich england where the new day begins. Rest or the world is ahead or behind this time. Central Standard time= 5 hours ahead of GMT
Lenticularis clouds
Lens clouds they are often comparable in appearance to len
1-800-WX-BRIEF
The FAA's online and phone Flight Service whereby weather conditions, NOTAMs, and other important information can be obtained.
cumulonimbus cloud
Thunderstorm clouds. Tall, rising clouds that produce rain. Nimbus=rain
Alto clouds
are "middle" clouds from 5,000 to 20,000 feet AGL. soprano,alto, tenor. Middle
Low-level clouds
are those clouds from the surface to 6,500 feet AGL. example: cumolous clouds
Castellanos clouds
castle /tiered clouds
High-level clouds
cirrus clouds of high level clouds
Automated Surface Observing Systems (ASOS)
combination of many federal weather agencies.The asos systems serves as the nation's primary surface weather observing system
front
different temperature of moving air mass
Advection Fog
forms when relatively warm, moist air moves over cool water as the temperature drops. The water cools the air to the dew point, resulting in fog.
air mass
is a body of air with horizontally uniform temperature, humidity, andpressure.
latitude
is a geographic coordinate that specifies the north-south position of a point on the Earth's surface. Latitude is an angle which ranges from 0° at the Equator to 90°(North or South) at the poles.
forecast
is a prediction or estimate of future events, especially coming weather or a financial trend.
Lithium Polymer(LiPo)
is a rechargeable battery of lithium-ion technology in apouch format. Unlike cylindrical and prismatic cells, LiPos come in a soft package or pouch, which makes them lighter but also less rigid.
Microburst
is a small, but strong downdraft that moves in a way opposite to a tornado.Microbursts are found in strong thunderstorms.
airport identifier
is a symbolic representation for the name andthe location of an airport, navigation aid, or weather station, and is used for manned air traffic control facilities in air traffic control, telecommunications, computer programming, weather reports, and related services.
knots
is a unit of speed equal to one nautical mile (1.852 km) per hour, approximately 1.15078 mph.
METARs(Meteorological Terminal Aviation Routine)
is an aviation routine weather report issued at hourly or half-hourly intervals. Itis a description of the meteorological elements observed at an airport at a specific time.
Abbreviated Weather Briefing
is for pilots who need to update previous weather data they have gathered or who only need a few bits of weather data to complete their weather picture.
Broken (BKN)
is the abbreviation for "broken" when used in METARs.
Clear (CLR)
is the abbreviation for "clear" when used in METARs.
Few (FEW)
is the abbreviation for "few" when used in METARs.
Hg
is the chemical symbol of Mercury.
lapse rate
is the rate at which air temperature falls with increasing altitude.
Altimeter setting
is the value of the atmospheric pressure used to adjust the sub-scale of a pressure altimeter so that it indicates the height of an aircraft above a known reference surface. This reference can be the mean sea level pressure, the pressure at the nearby surface airport or the pressure level of 29.92 inches of mercury which gives the standard flight levels.
Cirrus clouds
latin of hair. High altitude wispy clouds made of ice crystals
