METARs (Meteorological Terminal Aviation Routine)

A _____ is an aviation routine weather report issued at hourly or half-hourly intervals. It is a description of the meteorological elements observed at an airport at a specific time.

forecast

A __________ is a prediction or estimate of future events, especially coming weather or a financial trend.

Microburst

A ___________ is a small, but strong downdraft that moves in a way opposite to a tornado. ______________ are found in strong thunderstorms.

control station (CS)

A ________________ (__) is a land- or sea-based control center that provides the facilities for human control of unmanned vehicles in the air or in space.

Lithium Polymer (LiPo)

A ______________________ (____) is a rechargeable battery of lithium-ion technology in a pouch format. Unlike cylindrical and prismatic cells, _____ come in a soft package or pouch, which makes them lighter but also less rigid.

High-level clouds

All _______________ - where the base is above 20,000 ft - are a type of cirrus cloud. They do not normally pose any real threat of icing conditions or turbulence. They are clouds with extensive vertical development.

air mass

An __________ is a body of air with horizontally uniform temperature, humidity, and pressure.

airport identifier

An ___________________ (or location identifier) is a symbolic representation for the name and the 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.

Abbreviated Weather Briefing

An _____________________________ 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.

ambient

In weather, ___________ temperature refers to the current air temperature -- the overall temperature of the outdoor air that surrounds us. Unlike your maximum high and minimum low temperatures, it tells you nothing about what's forecast. It simply tells what the air temperature is right now, outside your door. As such, its value constantly changes minute-by-minute. In other words, ambient air temperature is the same thing as "ordinary" air temperature.

1-800-WX-BRIEF

The FAA's online and phone Flight Service whereby weather conditions, NOTAMs, and other important information can be obtained.

knots

The ____ is a unit of speed equal to one nautical mile (1.852 km) per hour, approximately 1.15078 mph.

Automated Surface Observing Systems (ASOS)

The _______________________ (____) program is a joint effort of the National Weather Service (NWS), the Federal Aviation Administration (FAA), and the Department of Defense (DOD). The ____ systems serves as the nation's primary surface weather observing network.

front

When an air mass that is different in prior properties advances upon a dissimilar air mass, the division line is referred to as a "_______."

Hg

__ is the chemical symbol of Mercury.

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.

longitude

__________ is a geographic coordinate that specifies the east-west position of a point on the Earth's surface. It is an angular measurement, usually expressed in degrees.

Alto clouds

_____________ are "middle" clouds from 5,000 to 20,000 feet AGL.

Low-level clouds

_____________ are those clouds from the surface to 6,500 feet AGL.

latitude

_____________ is a geographic coordinate that specifies the north-south position of a point on the Earth's surface. ______________ is an angle which ranges from 0° at the Equator to 90° (North or South) at the poles.

Cirrus clouds

______________ (thin and wispy), are the most common form of high-level clouds are thin and often wispy _____________. Typically found at heights greater than 20,000 feet (6,000 meters), ___________ are composed of ice crystals that originate from the freezing of supercooled water droplets.

lapse rate

______________ is the rate at which air temperature falls with increasing altitude.

Cumulus clouds

_______________ are clouds which have flat bases and are often described as "puffy", "cotton-like" or "fluffy" in appearance. Their name derives from the Latin __________-, meaning heap or pile. ______________ are low-level clouds, generally less than 2,000 m (6,600 ft) in altitude unless they are the more vertical cumulus congestus form.

Condensation

_______________ is the change of the physical state of matter from gas phase into liquid phase, and is the reverse of evaporation. The word most often refers to the water cycle.

Castellanos clouds

________________ often looks like a tiered weeding cake or castle, a single base with separate vertical development.

Fracto clouds

_________________ are small, ragged cloud fragments that are usually found under an ambient cloud base. They form or have broken off from a larger cloud, and are generally sheared by strong winds, giving them a jagged, shredded appearance. ________ have irregular patterns, appearing much like torn pieces of cotton candy.

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.

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.

cumulonimbus cloud

_________________, from the Latin cumulus ("heap") and nimbus ("rainstorm", "storm cloud"), is a dense, towering vertical cloud associated with thunderstorms and atmospheric instability, forming from water vapor carried by powerful upward air currents. If observed during a storm, these clouds may be referred to as thunderheads.

Middle-level clouds

__________________ range from 6,500 AGL up to 20,000 feet AGL.

Daylight Savings Time

____________________ (___), commonly referred to as __________________ in speech, and known as summer time in some countries, is the practice of advancing clocks during summer months so that evening daylight lasts longer, while sacrificing normal sunrise times.

Lenticularis clouds

____________________ are stationary clouds that form in the troposphere, typically in perpendicular alignment to the wind direction. They are often comparable in appearance to a lens or saucer.

Greenwich Mean Time (GMT)

_______________________ (___) is the mean solar time at the Royal Observatory in Greenwich, London. ___ was formerly used as the international civil time standard, now superseded in that function by Coordinated Universal Time (UTC). Today ___ is considered equivalent to UTC for UK civil purposes and for navigation is considered equivalent to UT1 (the modern form of mean solar time at 0° longitude)

Convective SIGMET

_____________________s are issued for severe thunderstorms with surface winds greater than 50 knots, hail at the surface greater than or equal to 3⁄4 inch in diameter, or tornadoes.
