“MT 310 AT 162/110”
decodes to mean Maximum Tops FL 3l0 at a bearing of 162 degrees and 110 NM from the station.
TB LGT 055-072
Turbulence intensity Light between 5500 feet and 7200 feet
SHRA” stand for
Rain showers.
Vertical visibility is shown on Terminal Aerodrome Forecasts {TAF) reports when the sky is
obscured.
Vertical visibility is coded as _____
VV
Widespread mountain obscurement
What information would be covered in an AIRMET?
On a Surface Analysis Weather Chart, isobars are usually spaced at intervals of
4 millibars.
On a weather Depiction Chart, what weather conditions would be contained in an unshaded area that is outlined by a smooth line?
Ceiling between 1,000 and 3,000 feet and/or visibility between 3 and 5 miles
A Weather Depiction Chart is useful to a pilot in determining
areas where weather conditions were reported above or below VFR minimums.
What weather phenomenon is causing IFR cooditions from central
Oklahoma west to the Texas bofder?
”=”) in northern Texas and Oklahoma indicate mist
The marginal weather ill ceritral Kentucky is due to low
ceiling.
The ‘2’ is visibility,
the’=’ sign is mist,
the circle with an X is Total Sky Obscuration. and
the 200 is a cloud layer at 20000 feet.
A Radar Summary Chart can be very helplul to a pilot because it graphical y displays
the intensity and movement of precipitation.
Interpret the weather symbol depicted in Utah on the 12 hour Significant
Weather Prognostic Chart.
Moderate turbulence, surface to 18,000 feet.
The enclosed shaded area associated with the low pressure system over
northern Utah is forecast to have
more than 50% coverage.
What percent coverege of severe thunderstroms is forecast to occur in the are of moderate risk in the north central united staes?
6-10
The bottom panel on this Convective Outlook Chart indicates
What is the expected duration of an individual microburst?
Seldom longer than 15 minutes from the time the burst strikes the ground until dissipation
Maximum downdrafts in a microburst encounter may be as strong as
6,000 feet per minute.
How long do the maximum intensity winds last in an individual mlcroburst?
2 to 4 minutes.
The position of fronts and pressure systems (as of chart time) is best determined by referring
Surface Analysis Chart
All ATC facilities using Radar Weather processors with the ability to determine precipitation
intensity will describe the intensity as
light, moderate, heavy, or extreme.
