A powerful tornado is a terrifying phenomenon that continues to defy decades of scientific efforts to predict it. During one of the worst tornado seasons on record, a NOVA camera team chased across the Midwest, capturing hair-raising footage of highly destructive twisters in action. But HUNT FOR THE SUPERTWISTER is much more than just another "extreme weather" show. Our story focuses on the efforts of two scientists at the University of Oklahoma to develop radically different approaches to forecasting twisters: one relies on "virtual tornados" created inside supercomputers, while the other involves hunting down real-life storms to collect data firsthand (the method that inspired the movie Twister). With jaw-dropping 3-D graphics generated by the National Center for Supercomputing Applications, NOVA's show features spectacular footage of these terrifying twisters. HUNT FOR THE SUPERTWISTER gives viewers a front-row seat to the risky and thrilling art of storm chasing, complete with the latest research findings and state-of-the-art visual effects.
