Release Title:

Marshall Radio
NASA scientist: Lightning studies may provide earlier tornado alerts

 
Four soundbites are available from NASA researcher Dr. Steve Goodman of the Global Hydrology and Climate Center in Huntsville, Ala. Three additional soundbites provide a variety of natural-sound backgrounds to accompany the story.
 
Soundbites Description

Soundbite #1
(120k)

Goodman explains the means by which weather forecasters traditionally spot possible tornado formations.

Runs: 17 seconds
Intro: "We know the key to the development …
Outcue: "… to warn of impending tornadoes."

Transcript: "We know the key to the development of tornados is the development and intensification of the storm updraft that precedes it. One of the things that's related to that is the in-cloud lightning rates. By better observing the in-cloud lightning activity, we think we can get improved lead-time to warn of impending tornados."


Soundbite #2
(52k)

Goodman explains the goal of tornado prediction.

Runs: 6 seconds
Intro: "Yeah, one of our goals…

Outcue: "… so we can save lives."

Transcript: "One of our goals is to improve our ability ti forecast severe storms and tornados so we can save lives."


Soundbite #3
(72k)

Goodman talks about the accuracy of current tornado prediction.

Runs: 9 seconds
Intro:
"Only about 30 percent of all rotating thunderstorms…"
Outcue: "… improve our warning accuracy."

Transcript: "Only about 30 percent of al the rotating thunderstorms ever make a tornado. We hope that with this new observation of the in-cloud lightning, we'll be able to improve our warning accuracy."



Soundbite #4

(80k)

Goodman says NASA eventually could provide comprehensive storm forecasting across the entire continent.

Runs: 11 seconds
Intro: "NASA’s future is to take our technology…"
Outcue: "
… and the adjacent oceans."

Transcript: "NASA's future is to take our technology in low-Earth orbit and to place it into geo-synchronous orbit, where we continuously monitor thunderstorms all the way from Canada down to South America and the adjacent oceans."



Soundbite #5

(136k)

17 seconds of heavy rain (natural sound)



Soundbite #6

(128k)

18 seconds of thunder (natural sound)



Soundbite #7

(160k)

22 seconds of high wind (natural sound)
