Subject: Soliciting Comments on the Experimental
Aviation
Winter Weather Dashboard January 3,
2012 to
April 15, 2012.
The National
Weather Service is soliciting comments on the
Experimental
Winter Weather Dashboard between December 28, 2011
and April 15,
2012.
The Experimental
Aviation Winter Weather Dashboard (AWWD)
depicts a
potential winter weather impact to the Core 30
Airports. The
AWWD is updated four times per day, the web
display indicates
the potential impact to each airport through a
matrix of color
coded boxes that depict nominal (green), slight
(yellow),
moderate (orange), and high (red) impact through
eighty-seven
forecast hours. The impact information
is
calculated using
the operational Short-Range Ensemble Forecast
(SREF) numerical
weather prediction system and climatology.
The AWWD was
developed to support the Federal Aviation
Administration
Air Traffic Control System Command Center to
coordinate long
range strategic winter weather planning by
providing
guidance on the impact from winter weather at major
airports.
The Experimental
Aviation Winter Weather Dashboard will only be
available at:
http://testbed.aviationweather.gov/winterdashboard
The AWWD renders
the potential impact to each airport, at three-
hourly forecast
intervals, based on certain thresholds of
forecast winter
weather conditions. The probability of
accumulated
snowfall/ice pellets, accumulated freezing rain, and
visibility are
used to determine the particular impact category
assigned to each
airport. The airports are split into four
separate impact
groups, based upon the airports’ ability to
operate during
winter weather conditions, which are based on
annual snowfall
climatology. Each group has a specific
probabilistic
threshold for snowfall/ice pellets, freezing rain,
and visibility
that determine the category.
If you have any
questions about this experimental forecast,
