Season 31, Episode 15 Hunt for the Supertwister

First Aired: March 30, 2004

“The Hunt for the Supertwister” follows University of Oklahoma scientists as they crisscross the Great Plains looking for reasons why tornadoes form so they can predict them more accurately.

The hour also recalls a twister that devastated Moore, Okla., in 1999 and one touched down in Maryland in 2002. And it looks at a computer model that displays what the narrator calls “an amazingly intricate dance of wind and moisture interacting with the environment.”
