Iowa State’s Tornado/Microburst Simulator has been in operation since 2005. It has helped Partha Sarkar and other researchers learn more about the wind loads created by tornadoes so engineers can design buildings that can stand up to windstorms. Pictured with the simulator are doctoral students, left to right, Nayan Deep Tiwari and Mahtab Goudarzi. Larger photo. Photos by Ryan Riley/College of Engineering.
