The tornado that leveled Moore, Okla., on Monday contained more energy than the atomic bomb dropped on Hiroshima, five separate meteorologists have found. Using real-time measurements, the meteorologists contacted by the Associated Press calculated the energy released during the tornado’s 40-plus minutes on the ground and concluded that it ranged from eight to more than 600 times the power of the Hiroshima bomb. After surveying the full-scale damage to homes, shopping centers, and schools, the National Weather Service upgraded the storm to a top-of-the-scale EF-5 tornado with winds estimated between 200 and 210 mph.
