Hunt for the Supertwister, released on the PBS TV series NOVA in March 2004, included several minutes of visualization from a numerical simulation of a tornadic supercell. The simulation, conducted by members of the Convective Modeling Group in collaboration with Lou Wicker of the National Severe Storms Laboratory, was transformed via state-of-the-art scientific visualization by NCSA's Visualization and Experimental Technologies Group into a stunning virtual storm chase. Additional information on visualizations generated through this project is available from Access. The simulated storm generated a long-lived tornado-like circulation, unprecedented in depth and longevity, which members of the team are investigating in pursuit of a greater understanding of the tornadogenesis process.
