Here is a link to a fantastic video of a supercell thunderstorm simulated by a supercomputer.  The work was done by Dr. Leigh Orf, who was a graduate student at University of Wisconsin-Madison at the same time I was. He is now doing these super in-depth visualizations of supercells and discerning how they form and ultimately spawn tornadoes.  He will be featured on Sunday’s WxGeeks show on the Weather Channel at noon EDT.  See the video and read more at: https://news.wisc.edu/a-scientist-and-a-supercomputer-re-create-a-tornado/#sthash.OS8lZqi1.fppuH5JP.dpuf
