(2) Broken lines display areas of CAT
(3) Depicts location of weather hazards,
including widespread sandstorms or dust
storms, squall lines, and tropical storms
(4) Arrows and wind flags show position and
speed of jet stream
(5) Square boxes show height of the
tropopause
NOTE: Meteorologists utilize the low-level
significant Wx Prog chart more than the
high-level. All high-level information is
available from other sources, e.g., constant
pressure charts. Many weather offices
choose to not receive this facsimile from
the National Weather Service.

and direction and outside air temperature
(OAT) for true altitudes of 6,000 ft, 9,000 ft, and
12,000 ft
NOTE: Charts are also available for the true
altitudes of 18,000 ft (500 mbs), 24,000 ft
(400 mbs), 30,000 ft (300 mbs), 34,000 ft
(250 mbs), 39,000 ft (200 mbs), which
approximate the constant pressure charts.
b.
Flight planning applications include
computation of ground speed, time en route,
and other performance figures
NOTE: Although winds aloft prognostic charts
are considered accurate for a quick ready
reference, the winds aloft forecast (FA) teletype
report is considered to be more accurate.
