WUSA 9 Chief Meteorologist
Topper Shutt answers viewers questions about how he
uses GOES satellite data to predict the weather with accuracy.On
February 4th, 2010, NASA launched the last satellite in the N-O-P series,
GOES-P to continue weather monitoring. In the future, the GOES-R series will
provide images with even greater resolution and speed of data delivery.

Topper Shutt/WUSA
9 Chief Meteorologist: Rain and showers develop probably late in the day on
ThursdayÉ
Étomorrow in the morning
snow, heavy at times, 48 inches during the morningÉ
Éwinds picking up
Northeasterly, 15 to 30 and gusty, becoming North-Northwesterly at 20 to 40É
É and then upper 60s and
sunshine Thursday, Friday.
Nicole Paschoal:
My name is Nicole Paschoal and I want to know how
Topper Shutt gets the weather as far as the data;
where that comes from and how far in advance does he know when something like a
storm is coming.
Topper Shutt/WUSA
9 Chief Meteorologist: We get all of our data pretty much from NOAA. Whether
itÕs current data or model data. In other words here is GOES satellite, this is
whatÕs happening now over the past 12 hours, so thatÕs invaluable to use.
I think generally speaking,
weather forecasting as a whole has gotten very good from 48 hours inside.
Nicole Paschoal:
When he gets the weather wrong, I mean, how quickly he knows that things have
shifted so that he can get the right information out?
Topper Shutt/WUSA
9 Chief Meteorologist: We can react almost immediately. I mean, if I see new
data that doesnÕt support the forecast, we can change it.
Mike Regan: My name is Mike
Regan. I would like to know from Topper Shutt how far
in advance he has to start doing his research to come up with one dayÕs
forecast.
Topper Shutt/WUSA
9 Chief Meteorologist: Well, Mike, it depends on the situation. The blizzard;
that storm itself was on our 7 day (radar) for 7 days. ThatÕs in winter time;
you get big, large, organized systems. In the summer time, itÕs not as easy so
it depends on the time of the year. Usually fall an winter itÕs a little easier
because the systems are larger.
Mike Regan: What types of
technological advancements are currently being made to try to improve the
percentage of accuracy with weather forecasts?
Topper Shutt/WUSA
9 Chief Meteorologist: Well now we get pictures more often. We were getting
pictures with the spinner back in the 70s and 80s and that was, I think, a
picture a half an hour or an hour and now we can get them every 15 minutes.
Jennifer Rivers: My name is
Jen Rivers and IÕd like to ask Topper Shutt how is
accurate weather data computed?
Topper Shutt/WUSA
9 Chief Meteorologist: Jennifer we use a lot of things; a lot of different
things go into a forecast. We use GOES data. We want to know the starting
point. See whatÕs happening now both the satellite GOES data, radar imagery,
current conditions, and then look at model data. There is so much model data
now. You have to know which models perform best under which situations. So,
itÕs often times a blend of current conditions, different model data,
climatology and local knowledge.
Doug Pierce: I am Doug
Pierce and IÕd like to ask Topper Shutt how do you use
satellite data to predict the weather?
Topper Shutt/WUSA
9 Chief Meteorologist: Doug, when the data comes from GOES, youÕve got infrared
satellite and youÕve got visible. Ok, so infrared measures temperature. But the
visible is kind of cool also for the same reason that as if you were in space
and looking down and you see exactly whatÕs there. And in the winter time itÕs
kind of cool to put a visible on a clear day and say ÒHey, see all the
whiteÉthatÕs not clouds, thatÕs snow coverÓ.
These satellites go a long
way to protect life and property. They help keep you safe, I mean, they help
us, you know, forecast the weather and so we can tell people what to do to stay
safe.
If you came to me and said I
am going to take one thing away from you, I would probably keep my GOES
satellite.
Satellite meteorology is
invaluable for determining dry lines; where the next line of thunderstorms will
developÉ.soÉyeahÉdonÕt take my satellite awayÉ
