1fa. Special Forecasts and Observations for PilotsThe National
Weather Service offers comprehensive weather information and forecasts
for aviators that is readily accessible from the Aviation Weather
Center’s Aviation Digital Data Service (ADDS). These data are readily
accessible at www.aviationweather.gov/adds(Figure 13-2-1). Some of the
more commonly used resources are described below. In some cases
information is presented using abbreviations and codes. For a complete
description of the codes and conventions used in these reports, you can
download at no cost a copy of Aviation Weather Services, Advisory
Circular 00-45G Change 1 (the URL is a long one, so it’s easiest to
access if you do a web search for the document and click on the
link).Aviation Routine Weather Reports (METARs)METARs are issued by
airports on an hourly basis and provide basic weather observations.
These reports present observations in a string of “groups.” Each airport
is represented by a four-digit identifier, followed by the time of
observation and a modifier report describing the data source. The coding
system used is somewhat archaic but usually easy to decipher; at other
times it is less obvious. But this problem is now remedied by the option
to click on a “translation” of the data that presents the information
in real words. The ADDS website also has an interactive Java tool that
allows the user to scroll over a map and have the data immediately
displayed.Aviation Selected Special Weather Reports (SPECIs)Though
METARs are issued every hour, weather conditions can sometimes change
dramatically between reports to a level that might be important for
aviators. When this happens, the AWC issues Aviation Selected Special
Weather Reports, or SPECIs, These are formatted the same way as METARS
and are differentiated from them by the use of SPECI as the type of
report preceding the station identifier.Pilot Weather Reports
(PIREPs)Weather data from airports help pilots prepare for takeoffs and
landings, but aviators also need information on flight conditions along
their flight route. This type of information is provided to the Aviation
Weather Center by pilots themselves and then disseminated to the rest
of the aviation community. PIREPs report on icing, turbulence, wind, or
other conditions at designated flight levels. As with METARs and SPECIs,
the ADDS website offers decoded versions of the reports and a Java tool
for easy access.Significant Meteorological Information (SIGMETs)SIGMETs
alert pilots to existing or expected weather conditions that could
impact aircraft safety. The threats could involve severe icing, heavy
turbulence, sandstorms or dust storms, or airborne volcanic ash. These
are issued by regional Meteorological. Watch Offices (MWOs) and remain
valid for a periods of up to four hours (they can be reissued an
unlimited number of times). Most SIGMETs are classified as
non-convective; convective SIGMETs are issued when thunderstorms may
lead to extreme turbulence, icing, or low-level wind shear.Short-Range
Surface Prognostic Charts (PROG) and Low-Level, Midlevel, and High-Level
Significant Weather (SIGWX) ChartsYou have seen numerous examples of
surface and upper-air maps in this and previous chapters of this text,
all of which are useful to pilots. In addition to these, the Aviation
Weather Center compiles specialized maps for the aviation community—both
for current conditions and forecasts up to 48 hours These maps are
tailored to the needs of pilots and highlight weather conditions of
special importance to aviators.FIGURE 13-2-1 Aviation Weather. The home
