Link of the week - Children’s publication features tornado animation

The online edition of the classic children's publication Weekly Reader recently featured a tornado animation produced at Pittsburgh Supercomputing Center.

PSC visualization specialist Greg Foss created the animation from a simulation by University of Oklahoma scientist Ming Xue. Xue, director of the Center for the Analysis and Prediction of Storms at Norman, used PSC supercomputing to simulate a 1977 supercell storm system and the high-intensity tornado it spawned. The results—which capture the tornado’s vortex structure, with wind speed of 260 miles per hour—represent the highest resolution simulation ever done of an entire thunderstorm and its tornado.

See PSC's article about this work, Retwistered Twister.
