Last year, Joshua Wadler, a hurricane hunter and a meteorologist at Embry-Riddle Aeronautical University, in Florida, went through the turbulence data from every NOAA hurricane flight since 2004, and two infamous ones from the nineteen-eighties. He measured how much each flight was thrown around along six axes of motion: roll, pitch, yaw, surge, sway, and heave. (The words alone can induce vertigo.)
