1. How often are METARs Every hour, or whenever the weather changes and necessitates a
issues? change. In that situation, a SPECI (special METAR) is issued.
2. What is a SPECI? A special METAR which is created in between the hourly METARs due
to a change in weather necessitating the change.
-Change of winds necessitating a new runway.
-WX changing from IFR to VFR or VFR to IFR.
3. Do METARs describe ac- METARs depict actual field conditions.
tual or forecast condi-
tions?
4. Define Radiation fog Shallow fog, ground fog. occurs on clear nights, little or no wind,
and small temp/DP spread (high relative humidity). Occurs at night or
daybreak. Radiation cools the ground. The ground cools the air. When
the air is cooled to the dew-point, fog forms.
5. Define Advection fog This fog forms when moist air moves over colder ground or water.
Common along the coast.
6. What is lake effect? De- Air moving across a sizeable lake absorbs water vapor.
scribe one major conse- Showers may appear on the leeward side if the air is colder than the
quence of lake effect in water. If the air is warmer than the water, fog often develops on the
winter. leeward side. In the winter, lake effect snow is a concern because as a
cold front passes over the warmer lake water, snow, instead of showers
will occur.
7. What happens when Small Temp/DP spread is essential to the formation of fog.
the Temperature/dew-
point are very close?
8. How often are TAFs is- Valid for a 24-hour period, TAFs are issued four times daily at 00Z,
sued? 06Z, 12Z, and 18Z, and updated as conditions warrant. TAFs include

information about wind speed and direction, visibility, present weather,
ceilings, and low-level wind shear.
9. Why is it important to Because you always need to use the most up to date information and
know when the various knowing when the next forecast is coming up is essential for making
charts and reports are is- critcal flight decisions. For instance, if it is 05:55Z, the TAF from 00Z
sued? is the most up-to-date forecast, however, in only 5 minutes, the 06Z
TAF will be the most up-to-date forecast and could contain critical
information.
10. What is an Amended An amended TAF is issued when the current TAF no longer adequately
TAF? describes the ongoing weather or the forecaster feels the TAF is not
representative of the current or expected weather.
11. Which sky conditions are Broken, Overcast, VV (vertical visibility[indefinite ceiling])
considered a ceiling?
12. How often is a surface starting at 00Z at 3 hour intervals. (8 times a day)
analysis chart issued?
13. What are the primary They show pressure patterns, fronts, and information on individual
features of a surface reporting stations. The pressure patterns are shown by isobars.
analysis chart? Isobars
Pressure Systems
Fronts
Troughs and Ridges
Station Models
14. How is a surface analysis It is used to determine sky cover, the types of clouds. SLP, pressure
chart used? change, precip, temp/dew point, present wx, wind. They can be used
to locate the jetstream, turbulence, and wind shear.
15. The closer the isobars are together, the stronger the winds will be.

What is the relation-
ship between isobars
and surface winds?
16. How often is a Weather Every 3 hours starting at 01Z
depiction chart issued?
17. What is a weather depic- A weather chart to be used for flight planning by giving an overall
tion chart? picture of the WX across the US.
18. What is a Radar summa- A radar summary chart is a graphically depicted collection of radar
ry chart? weather reports.
19. Does the Radar summa- Observed, hourly.
ry chart depict forecast
conditions, or observed
conditions? How often?
20. What is the difference The visible images display cloud cover. The infrared images display
between visible and in- the earth in a manner that correlates with temperature. Generally
frared Satellite imagery? speaking, the warmer an object, the more infrared energy it emits.
21. What does water vapor The water vapor images display the earth in a manner that correlates
imagery show on the to quantity of water vapor in the upper portions of the atmosphere
Satellite imagery? (25,000 feet and higher in general). The most useful information to be
gained from the water vapor images is the locations of storm systems
and the jet stream.
22. What do the Valid Times 12 and 24 hours. They indicate that the prog chart is valid for 12 hours
indicate? from the time issued, or 24 hours from the time issued.
(on a prog chart)
23. How many times are 4 times a day. 00Z, 06Z, 12Z, 18Z.
