Some of that data came from the sheer size of the storm (similar supercells can stretch more than 12 miles high). But Orf needed most of the power in order to capture all the details and see the whole system at a high resolution. To get started, he used observations from an actual storm that raged through central Oklahoma in 2011. Then he created a digital version similar to the real thing, spinning together the most high-resolution supercell simulation ever made. “For the first time, we’ve been able to peer into the inner workings of a supercell that produces a tornado, and we’re able to watch that process occur,” Orf says.
