METAR
The FAA identified three distinct types of weather information.
What are observation, analyses, and forecasts?
This is a Terminal Aerodrome Forecast
What is a TAF report?
This modifies air density and creates circulation patterns.
What is the heating of the earth's surface?
This refers to mountains, valleys, rivers, or craters on the surface that can affect the flow of wind.
What is Ground Topography?
This can happen on clear cool night (air cooled by warm ground).
What is surface based inversion?
These acronyms are used for the three types of observation reports
What are METAR, SPECI, and PIREP?
This is the radius around an airport.
What is 5 Statute Miles (SM)
The mesosphere lies on top of this atmospheric layer.
In regards to Convective Currents, plowed ground, rocks, sand, and barren land give off a larger amount of heat that results in this.
What is rising air?
This inversion occurs when warm air spreads over a layer of cooler air, or cooler air is forced under a layer of warm air.
What is frontal inversion?
This Automated Surface Observing System (ASOS) uses what code for NO Precipitation Discriminator
What is A01?
TAF reports are not usually issued for all airports, just this type of airport.
What are larger airports?
When as air density increases the performance of an aircraft will increase. This is called...
What is lower density altitude?
This is commonly associated with passing frontal systems, thunderstorms, and temperature inversions.
What is low-level wind shear?
The relationship between dewpoint and temperature deffines this concept.
What is relative humidity?
This is maximum number of groups for the body of a METAR or SPECI report
What is 11?
The forcast states that wind will blow from 160° at 15 knots with gusts at 25 knots from this specific time.

What is from 1500Z?
This is the pressure within the atmosphere of the Earth or that of another planet.
What is atmospheric pressure (barometric)
This has the most severe type of low-level wind shear and has typical diameter of 1-2 miles that can last 5-15 minutes.
What is a Microburst?
When this occurs, the moisture in the air condenses and deposits itself on the ground, buildings, and other objects like cars and aircraft.
What is Dew and Frost?
This major section of a METAR or SPECI report consists of 2 categories.
What is the remarks sections?
This shows the 11th day at 1200Z to the 12th day at 1200Z.

What is the start and end of the forecasts.
These standard conditions are the basis for most aircraft performance data standard sea level pressure.
What is 29.92 HG and 15° C (59° F)
This flight crashed on August 2, 1985 due to a Microburst that resulted in 136 fatalities.
What was Delta Flight 191?
To pilots, this cloud is perhaps the most dangerous cloud type.
What is a cumulonimbus cloud?
