Noted: A dozen or so years later, when he arrived at the University of Wisconsin–Madison and fell in love with coding, he learned about the community of scientists who had been using computers to simulate storms since the 1970s. In the earliest renderings, most computers couldn’t re-create any features of a tornado that were less than a kilometer wide or tall, meaning they could re-create the broad contours of a storm but none of its important details. Over time, driven in part by advances in microprocessing power, scientists gradually sharpened the resolution from 1 kilometer to 500 meters and eventually to 100 meters, the storm and the tornado steadily coming into focus.
