Short summary

Hurricane Irene generated strong near-inertial currents in ocean waters when passing over the Mid-Atlantic Bight of the US East Coast in late August 2011. It is demonstrated that a combination of valuable field data and detailed model results can be exploited to study the development and decay mechanism of this event. The near-inertial kinetic energy is shown to mainly have been gained from wind power during the hurricane event. Its decay, however, depends on several factors.
