The forecast before the storm

How supercomputers and hybrid workflows helped beat tornadoes to the chase

Chasing tornadoes won’t get you very far, if your goal is to understand how tornadoes form. To get results, researchers need to get their instruments on the ground before the tornado touches down.

That’s the big catch 22 of VORTEX2 (Verification of the Origins of Rotation in Tornadoes Experiment), according to principal investigator Joshua Wurman. Current techniques predict tornadoes an average of only 13 minutes in advance, a fact that makes it difficult to evacuate or properly prepare for the impending disaster. To improve that lead time, or learn how to predict how destructive a tornado will be, scientists need data recorded as the tornadoes form.

“In order for us to collect good data we had to surround a supercell perhaps 40 or 50 minutes before the tornado,” Wurman explained. Yet, he added, “if we knew exactly when to surround the storm, one of the big motivations of VORTEX2 wouldn’t be there.”
