Supercomputer simulation looks inside of 2011's deadliest tornado Video Description

Leigh Orf at the University of Wisconsin-Madison had the 2011 storm simulated by the University of Illinois' Blue Waters machine -- tasking the supercomputer with breaking the enormous supercell into almost two billion small chunks spread over a 75 square mile area. The wind speed, temperature, pressure humidity and precipitation of each of those smaller sections was individually calculated before reassembling the bits into one large recreation of the entire storm. The task took three days and 20,000 of Blue Waters' processing cores, but it was worth it.
