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
