One of the most promising tools on the horizon
is phased array radar.
Its rapid-scanning ability lets NOAA researchers
observe storms like never before.
But will it be more useful for the National Weather Service?
Will it result in earlier warnings for you?
Let’s find out what happens when forecasters go hands-on.
Forecaster: still a pronounced three body scatter spike.
Pam: The PARISE is the Phased Array Radar
Innovative Sensing Experiment.
We bring in forecasters from the National Weather Service
and we have them work cases - archived cases -
simulated real-time.
And they issue warnings and update statements
just as they would in the real world.
So then that allows us to learn how the data
is impacting their process... is it of benefit to them?
Does it increase their warning lead-time?
The past couple years have been focused on tornadic storms
that cause light to moderate damage.
With current radar, the average warning lead-time
for these tornadoes is about 12 and a half minutes.
What we found from 12 forecasters working events like that
their average lead time was 21 minutes
and so that suggests that having this rapid update data
say on the order of a minute really can make a difference
in getting warning out and giving people time to respond.
So far, so good.
The experiment is set to continue annually
and will cover all types of severe weather events.
