Subject: Amended: Soliciting Comments on the
Experimental
Aviation Winter Weather Dashboard
through
April 15, 2013.
Amended to extend
the solicitation of comments on the
Experimental
Winter Weather Dashboard through April 15, 2013.
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 impact through 87 forecast
hours:
- nominal (green)
- slight (yellow)
- moderate (orange)
- high (red) impact.
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
3-hourly forecast
intervals, based on certain thresholds of
forecast winter weather conditions. The probability
of
accumulated snowfall, 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 is based on annual
snowfall
climatology. Each group has a specific probabilistic
threshold
for snowfall/ice pellets, freezing rain, and visibility
that
determine the category.
